All +middlewares will populate the `req.body` property with the parsed body when +the `Content-Type` request header matches the `type` option, or an empty +object (`{}`) if there was no body to parse, the `Content-Type` was not matched, +or an error occurred. + +The various errors returned by this module are described in the +[errors section](#errors). + +### bodyParser.json([options]) + +Returns middleware that only parses `json` and only looks at requests where +the `Content-Type` header matches the `type` option. This parser accepts any +Unicode encoding of the body and supports automatic inflation of `gzip` and +`deflate` encodings. + +A new `body` object containing the parsed data is populated on the `request` +object after the middleware (i.e. `req.body`). + +#### Options + +The `json` function takes an optional `options` object that may contain any of +the following keys: + +##### inflate + +When set to `true`, then deflated (compressed) bodies will be inflated; when +`false`, deflated bodies are rejected. Defaults to `true`. + +##### limit + +Controls the maximum request body size. If this is a number, then the value +specifies the number of bytes; if it is a string, the value is passed to the +[bytes](https://www.npmjs.com/package/bytes) library for parsing. Defaults +to `'100kb'`. + +##### reviver + +The `reviver` option is passed directly to `JSON.parse` as the second +argument. You can find more information on this argument +[in the MDN documentation about JSON.parse](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/JSON/parse#Example.3A_Using_the_reviver_parameter). + +##### strict + +When set to `true`, will only accept arrays and objects; when `false` will +accept anything `JSON.parse` accepts. Defaults to `true`. + +##### type + +The `type` option is used to determine what media type the middleware will +parse. This option can be a string, array of strings, or a function. If not a +function, `type` option is passed directly to the +[type-is](https://www.npmjs.org/package/type-is#readme) library and this can +be an extension name (like `json`), a mime type (like `application/json`), or +a mime type with a wildcard (like `*/*` or `*/json`). If a function, the `type` +option is called as `fn(req)` and the request is parsed if it returns a truthy +value. Defaults to `application/json`. + +##### verify + +The `verify` option, if supplied, is called as `verify(req, res, buf, encoding)`, +where `buf` is a `Buffer` of the raw request body and `encoding` is the +encoding of the request. The parsing can be aborted by throwing an error. + +### bodyParser.raw([options]) + +Returns middleware that parses all bodies as a `Buffer` and only looks at +requests where the `Content-Type` header matches the `type` option.

If a function, the `type` option is called as `fn(req)` +and the request is parsed if it returns a truthy value. Defaults to +`application/octet-stream`. + +##### verify + +The `verify` option, if supplied, is called as `verify(req, res, buf, encoding)`, +where `buf` is a `Buffer` of the raw request body and `encoding` is the +encoding of the request. The parsing can be aborted by throwing an error. + +### bodyParser.text([options]) + +Returns middleware that parses all bodies as a string and only looks at +requests where the `Content-Type` header matches the `type` option. This +parser supports automatic inflation of `gzip` and `deflate` encodings. + +A new `body` string containing the parsed data is populated on the `request` +object after the middleware (i.e. `req.body`). This will be a string of the +body. + +#### Options + +The `text` function takes an optional `options` object that may contain any of +the following keys: + +##### defaultCharset + +Specify the default character set for the text content if the charset is not +specified in the `Content-Type` header of the request. Defaults to `utf-8`. + +##### inflate + +When set to `true`, then deflated (compressed) bodies will be inflated; when +`false`, deflated bodies are rejected. Defaults to `true`. + +##### limit + +Controls the maximum request body size. If this is a number, then the value +specifies the number of bytes; if it is a string, the value is passed to the +[bytes](https://www.npmjs.com/package/bytes) library for parsing. Defaults +to `'100kb'`. + +##### type + +The `type` option is used to determine what media type the middleware will +parse. This option can be a string, array of strings, or a function. If not +a function, `type` option is passed directly to the +[type-is](https://www.npmjs.org/package/type-is#readme) library and this can +be an extension name (like `txt`), a mime type (like `text/plain`), or a mime +type with a wildcard (like `*/*` or `text/*`). If a function, the `type` +option is called as `fn(req)` and the request is parsed if it returns a +truthy value. Defaults to `text/plain`. + +##### verify + +The `verify` option, if supplied, is called as `verify(req, res, buf, encoding)`, +where `buf` is a `Buffer` of the raw request body and `encoding` is the +encoding of the request. The parsing can be aborted by throwing an error. + +### bodyParser.urlencoded([options]) + +Returns middleware that only parses `urlencoded` bodies and only looks at +requests where the `Content-Type` header matches the `type` option. This +parser accepts only UTF-8 encoding of the body and supports automatic +inflation of `gzip` and `deflate` encodings. + +A new `body` object containing the parsed data is populated on the `request` +object after the middleware (i.e. `req.body`). This object will contain +key-value pairs, where the value can be a string or array (when `extended` is +`false`), or any type (when `extended` is `true`). + +#### Options + +The `urlencoded` function takes an optional `options` object that may contain +any of the following keys: + +##### extended + +The `extended` option allows to choose between parsing the URL-encoded data +with the `querystring` library (when `false`) or the `qs` library (when +`true`). The "extended" syntax allows for rich objects and arrays to be +encoded into the URL-encoded format, allowing for a JSON-like experience +with URL-encoded. For more information, please +[see the qs library](https://www.npmjs.org/package/qs#readme). + +Defaults to `true`, but using the default has been deprecated. Please +research into the difference between `qs` and `querystring` and choose the +appropriate setting. + +##### inflate + +When set to `true`, then deflated (compressed) bodies will be inflated; when +`false`, deflated bodies are rejected. Defaults to `true`. + +##### limit + +Controls the maximum request body size. If this is a number, then the value +specifies the number of bytes; if it is a string, the value is passed to the +[bytes](https://www.npmjs.com/package/bytes) library for parsing. Defaults +to `'100kb'`. + +##### parameterLimit + +The `parameterLimit` option controls the maximum number of parameters that +are allowed in the URL-encoded data. If a request contains more parameters +than this value, a 413 will be returned to the client. Defaults to `1000`. + +##### type + +The `type` option is used to determine what media type the middleware will +parse. This option can be a string, array of strings, or a function. If not +a function, `type` option is passed directly to the +[type-is](https://www.npmjs.org/package/type-is#readme) library and this can +be an extension name (like `urlencoded`), a mime type (like +`application/x-www-form-urlencoded`), or a mime type with a wildcard (like +`*/x-www-form-urlencoded`). If a function, the `type` option is called as +`fn(req)` and the request is parsed if it returns a truthy value. Defaults +to `application/x-www-form-urlencoded`. + +##### verify + +The `verify` option, if supplied, is called as `verify(req, res, buf, encoding)`, +where `buf` is a `Buffer` of the raw request body and `encoding` is the +encoding of the request. The parsing can be aborted by throwing an error. + +#### depth + +The `depth` option is used to configure the maximum depth of the `qs` library when `extended` is `true`. This allows you to limit the amount of keys that are parsed and can be useful to prevent certain types of abuse. Defaults to `32`. It is recommended to keep this value as low as possible. + +## Errors + +The middlewares provided by this module create errors using the +[`http-errors` module](https://www.npmjs.com/package/http-errors). The errors +will typically have a `status`/`statusCode` property that contains the suggested +HTTP response code, an `expose` property to determine if the `message` property +should be displayed to the client, a `type` property to determine the type of +error without matching against the `message`, and a `body` property containing +the read body, if available. + +The following are the common errors created, though any error can come through +for various reasons. + +### content encoding unsupported + +This error will occur when the request had a `Content-Encoding` header that +contained an encoding but the "inflation" option was set to `false`. The +`status` property is set to `415`, the `type` property is set to +`'encoding.unsupported'`, and the `charset` property will be set to the +encoding that is unsupported. + +### entity parse failed + +This error will occur when the request contained an entity that could not be +parsed by the middleware. The `status` property is set to `400`, the `type` +property is set to `'entity.parse.failed'`, and the `body` property is set to +the entity value that failed parsing. + +### entity verify failed + +This error will occur when the request contained an entity that could not be +failed verification by the defined `verify` option. The `status` property is +set to `403`, the `type` property is set to `'entity.verify.failed'`, and the +`body` property is set to the entity value that failed verification. + +### request aborted + +This error will occur when the request is aborted by the client before reading +the body has finished. The `received` property will be set to the number of +bytes received before the request was aborted and the `expected` property is +set to the number of expected bytes. The `status` property is set to `400` +and `type` property is set to `'request.aborted'`. + +### request entity too large + +This error will occur when the request body's size is larger than the "limit" +option. The `limit` property will be set to the byte limit and the `length` +property will be set to the request body's length. The `status` property is +set to `413` and the `type` property is set to `'entity.too.large'`. + +### request size did not match content length + +This error will occur when the request's length did not match the length from +the `Content-Length` header. This typically occurs when the request is malformed, +typically when the `Content-Length` header was calculated based on characters +instead of bytes. The `status` property is set to `400` and the `type` property +is set to `'request.size.invalid'`. + +### stream encoding should not be set + +This error will occur when something called the `req.setEncoding` method prior +to this middleware. This module operates directly on bytes only and you cannot +call `req.setEncoding` when using this module. The `status` property is set to +`500` and the `type` property is set to `'stream.encoding.set'`. + +### stream is not readable + +This error will occur when the request is no longer readable when this middleware +attempts to read it. This typically means something other than a middleware from +this module read the request body already and the middleware was also configured to +read the same request. The `status` property is set to `500` and the `type` +property is set to `'stream.not.readable'`. + +### too many parameters + +This error will occur when the content of the request exceeds the configured +`parameterLimit` for the `urlencoded` parser. The `status` property is set to +`413` and the `type` property is set to `'parameters.too.many'`. + +### unsupported charset "BOGUS" + +This error will occur when the request had a charset parameter in the +`Content-Type` header, but the `iconv-lite` module does not support it OR the +parser does not support it. The charset is contained in the message as well +as in the `charset` property. The `status` property is set to `415`, the +`type` property is set to `'charset.unsupported'`, and the `charset` property +is set to the charset that is unsupported. + +### unsupported content encoding "bogus" + +This error will occur when the request had a `Content-Encoding` header that +contained an unsupported encoding. The encoding is contained in the message +as well as in the `encoding` property. The `status` property is set to `415`, +the `type` property is set to `'encoding.unsupported'`, and the `encoding` +property is set to the encoding that is unsupported. + +### The input exceeded the depth + +This error occurs when using `bodyParser.urlencoded` with the `extended` property set to `true` and the input exceeds the configured `depth` option. The `status` property is set to `400`. It is recommended to review the `depth` option and evaluate if it requires a higher value. When the `depth` option is set to `32` (default value), the error will not be thrown. + +## Examples + +### Express/Connect top-level generic + +This example demonstrates adding a generic JSON and URL-encoded parser as a +top-level middleware, which will parse the bodies of all incoming requests. +This is the simplest setup. + +```js +var express = require('express') +var bodyParser = require('body-parser') + +var app = express() + +// parse application/x-www-form-urlencoded +app.use(bodyParser.urlencoded({ extended: false })) + +// parse application/json +app.use(bodyParser.json()) + +app.use(function (req, res) { + res.setHeader('Content-Type', 'text/plain') + res.write('you posted:\n') + res.end(JSON.stringify(req.body, null, 2)) +}) +``` + +### Express route-specific + +This example demonstrates adding body parsers specifically to the routes that +need them.

In other words: + +- [brace expansion](#brace-expansion) is for generating new lists +- [brace matching](#brace-matching) is for filtering existing lists + +
+More about brace expansion (click to expand) + +There are two main types of brace expansion: + +1. **lists**: which are defined using comma-separated values inside curly braces: `{a,b,c}` +2. **sequences**: which are defined using a starting value and an ending value, separated by two dots: `a{1..3}b`. Optionally, a third argument may be passed to define a "step" or increment to use: `a{1..100..10}b`. These are also sometimes referred to as "ranges". + +Here are some example brace patterns to illustrate how they work: + +**Sets** + +``` +{a,b,c} => a b c +{a,b,c}{1,2} => a1 a2 b1 b2 c1 c2 +``` + +**Sequences** + +``` +{1..9} => 1 2 3 4 5 6 7 8 9 +{4..-4} => 4 3 2 1 0 -1 -2 -3 -4 +{1..20..3} => 1 4 7 10 13 16 19 +{a..j} => a b c d e f g h i j +{j..a} => j i h g f e d c b a +{a..z..3} => a d g j m p s v y +``` + +**Combination** + +Sets and sequences can be mixed together or used along with any other strings. + +``` +{a,b,c}{1..3} => a1 a2 a3 b1 b2 b3 c1 c2 c3 +foo/{a,b,c}/bar => foo/a/bar foo/b/bar foo/c/bar +``` + +The fact that braces can be "expanded" from relatively simple patterns makes them ideal for quickly generating test fixtures, file paths, and similar use cases. + +## Brace matching + +In addition to _expansion_, brace patterns are also useful for performing regular-expression-like matching. + +For example, the pattern `foo/{1..3}/bar` would match any of following strings: + +``` +foo/1/bar +foo/2/bar +foo/3/bar +``` + +But not: + +``` +baz/1/qux +baz/2/qux +baz/3/qux +``` + +Braces can also be combined with [glob patterns](https://github.com/jonschlinkert/micromatch) to perform more advanced wildcard matching. For example, the pattern `*/{1..3}/*` would match any of following strings: + +``` +foo/1/bar +foo/2/bar +foo/3/bar +baz/1/qux +baz/2/qux +baz/3/qux +``` + +## Brace matching pitfalls + +Although brace patterns offer a user-friendly way of matching ranges or sets of strings, there are also some major disadvantages and potential risks you should be aware of. + +### tldr + +**"brace bombs"** + +- brace expansion can eat up a huge amount of processing resources +- as brace patterns increase _linearly in size_, the system resources required to expand the pattern increase exponentially +- users can accidentally (or intentially) exhaust your system's resources resulting in the equivalent of a DoS attack (bonus: no programming knowledge is required!) + +For a more detailed explanation with examples, see the [geometric complexity](#geometric-complexity) section. + +### The solution + +Jump to the [performance section](#performance) to see how Braces solves this problem in comparison to other libraries. + +### Geometric complexity + +At minimum, brace patterns with sets limited to two elements have quadradic or `O(n^2)` complexity. But the complexity of the algorithm increases exponentially as the number of sets, _and elements per set_, increases, which is `O(n^c)`. + +For example, the following sets demonstrate quadratic (`O(n^2)`) complexity: + +``` +{1,2}{3,4} => (2X2) => 13 14 23 24 +{1,2}{3,4}{5,6} => (2X2X2) => 135 136 145 146 235 236 245 246 +``` + +But add an element to a set, and we get a n-fold Cartesian product with `O(n^c)` complexity: + +``` +{1,2,3}{4,5,6}{7,8,9} => (3X3X3) => 147 148 149 157 158 159 167 168 169 247 248 + 249 257 258 259 267 268 269 347 348 349 357 + 358 359 367 368 369 +``` + +Now, imagine how this complexity grows given that each element is a n-tuple: + +``` +{1..100}{1..100} => (100X100) => 10,000 elements (38.4 kB) +{1..100}{1..100}{1..100} => (100X100X100) => 1,000,000 elements (5.76 MB) +``` + +Although these examples are clearly contrived, they demonstrate how brace patterns can quickly grow out of control. + +**More information** + +Interested in learning more about brace expansion? + +- [linuxjournal/bash-brace-expansion](http://www.linuxjournal.com/content/bash-brace-expansion) +- [rosettacode/Brace_expansion](https://rosettacode.org/wiki/Brace_expansion) +- [cartesian product](https://en.wikipedia.org/wiki/Cartesian_product) + +
+ +## Performance + +Braces is not only screaming fast, it's also more accurate the other brace expansion libraries. + +### Better algorithms + +Fortunately there is a solution to the ["brace bomb" problem](#brace-matching-pitfalls): _don't expand brace patterns into an array when they're used for matching_. + +Instead, convert the pattern into an optimized regular expression.

Check out our blog post about it: [Chokidar 3: How to save 32TB of traffic every week](https://paulmillr.com/posts/chokidar-3-save-32tb-of-traffic/) + +## How? + +Chokidar does still rely on the Node.js core `fs` module, but when using +`fs.watch` and `fs.watchFile` for watching, it normalizes the events it +receives, often checking for truth by getting file stats and/or dir contents. + +On MacOS, chokidar by default uses a native extension exposing the Darwin +`FSEvents` API. This provides very efficient recursive watching compared with +implementations like `kqueue` available on most \*nix platforms. Chokidar still +does have to do some work to normalize the events received that way as well. + +On most other platforms, the `fs.watch`-based implementation is the default, which +avoids polling and keeps CPU usage down. Be advised that chokidar will initiate +watchers recursively for everything within scope of the paths that have been +specified, so be judicious about not wasting system resources by watching much +more than needed. + +## Getting started + +Install with npm: + +```sh +npm install chokidar +``` + +Then `require` and use it in your code: + +```javascript +const chokidar = require('chokidar'); + +// One-liner for current directory +chokidar.watch('.').on('all', (event, path) => { + console.log(event, path); +}); +``` + +## API + +```javascript +// Example of a more typical implementation structure + +// Initialize watcher. +const watcher = chokidar.watch('file, dir, glob, or array', { + ignored: /(^|[\/\\])\../, // ignore dotfiles + persistent: true +}); + +// Something to use when events are received. +const log = console.log.bind(console); +// Add event listeners. +watcher + .on('add', path => log(`File ${path} has been added`)) + .on('change', path => log(`File ${path} has been changed`)) + .on('unlink', path => log(`File ${path} has been removed`)); + +// More possible events. +watcher + .on('addDir', path => log(`Directory ${path} has been added`)) + .on('unlinkDir', path => log(`Directory ${path} has been removed`)) + .on('error', error => log(`Watcher error: ${error}`)) + .on('ready', () => log('Initial scan complete. Ready for changes')) + .on('raw', (event, path, details) => { // internal + log('Raw event info:', event, path, details); + }); + +// 'add', 'addDir' and 'change' events also receive stat() results as second +// argument when available: https://nodejs.org/api/fs.html#fs_class_fs_stats +watcher.on('change', (path, stats) => { + if (stats) console.log(`File ${path} changed size to ${stats.size}`); +}); + +// Watch new files. +watcher.add('new-file'); +watcher.add(['new-file-2', 'new-file-3', '**/other-file*']); + +// Get list of actual paths being watched on the filesystem +var watchedPaths = watcher.getWatched(); + +// Un-watch some files. +await watcher.unwatch('new-file*'); + +// Stop watching. +// The method is async! +watcher.close().then(() => console.log('closed')); + +// Full list of options.

Paths to files, dirs to be watched +recursively, or glob patterns. + - Note: globs must not contain windows separators (`\`), + because that's how they work by the standard — + you'll need to replace them with forward slashes (`/`). + - Note 2: for additional glob documentation, check out low-level + library: [picomatch](https://github.com/micromatch/picomatch). +* `options` (object) Options object as defined below: + +#### Persistence + +* `persistent` (default: `true`). Indicates whether the process +should continue to run as long as files are being watched. If set to +`false` when using `fsevents` to watch, no more events will be emitted +after `ready`, even if the process continues to run. + +#### Path filtering + +* `ignored` ([anymatch](https://github.com/es128/anymatch)-compatible definition) +Defines files/paths to be ignored. The whole relative or absolute path is +tested, not just filename. If a function with two arguments is provided, it +gets called twice per path - once with a single argument (the path), second +time with two arguments (the path and the +[`fs.Stats`](https://nodejs.org/api/fs.html#fs_class_fs_stats) +object of that path). +* `ignoreInitial` (default: `false`). If set to `false` then `add`/`addDir` events are also emitted for matching paths while +instantiating the watching as chokidar discovers these file paths (before the `ready` event). +* `followSymlinks` (default: `true`). When `false`, only the +symlinks themselves will be watched for changes instead of following +the link references and bubbling events through the link's path. +* `cwd` (no default). The base directory from which watch `paths` are to be +derived. Paths emitted with events will be relative to this. +* `disableGlobbing` (default: `false`). If set to `true` then the strings passed to `.watch()` and `.add()` are treated as +literal path names, even if they look like globs. + +#### Performance + +* `usePolling` (default: `false`). +Whether to use fs.watchFile (backed by polling), or fs.watch. If polling +leads to high CPU utilization, consider setting this to `false`. It is +typically necessary to **set this to `true` to successfully watch files over +a network**, and it may be necessary to successfully watch files in other +non-standard situations. Setting to `true` explicitly on MacOS overrides the +`useFsEvents` default. You may also set the CHOKIDAR_USEPOLLING env variable +to true (1) or false (0) in order to override this option. +* _Polling-specific settings_ (effective when `usePolling: true`) + * `interval` (default: `100`). Interval of file system polling, in milliseconds. You may also + set the CHOKIDAR_INTERVAL env variable to override this option. + * `binaryInterval` (default: `300`). Interval of file system + polling for binary files. + ([see list of binary extensions](https://github.com/sindresorhus/binary-extensions/blob/master/binary-extensions.json)) +* `useFsEvents` (default: `true` on MacOS). Whether to use the +`fsevents` watching interface if available. When set to `true` explicitly +and `fsevents` is available this supercedes the `usePolling` setting. When +set to `false` on MacOS, `usePolling: true` becomes the default. +* `alwaysStat` (default: `false`). If relying upon the +[`fs.Stats`](https://nodejs.org/api/fs.html#fs_class_fs_stats) +object that may get passed with `add`, `addDir`, and `change` events, set +this to `true` to ensure it is provided even in cases where it wasn't +already available from the underlying watch events. +* `depth` (default: `undefined`). If set, limits how many levels of +subdirectories will be traversed. +* `awaitWriteFinish` (default: `false`). +By default, the `add` event will fire when a file first appears on disk, before +the entire file has been written. Furthermore, in some cases some `change` +events will be emitted while the file is being written. In some cases, +especially when watching for large files there will be a need to wait for the +write operation to finish before responding to a file creation or modification. +Setting `awaitWriteFinish` to `true` (or a truthy value) will poll file size, +holding its `add` and `change` events until the size does not change for a +configurable amount of time. The appropriate duration setting is heavily +dependent on the OS and hardware. For accurate detection this parameter should +be relatively high, making file watching much less responsive. +Use with caution. + * *`options.awaitWriteFinish` can be set to an object in order to adjust + timing params:* + * `awaitWriteFinish.stabilityThreshold` (default: 2000). Amount of time in + milliseconds for a file size to remain constant before emitting its event. + * `awaitWriteFinish.pollInterval` (default: 100). File size polling interval, in milliseconds. + +#### Errors + +* `ignorePermissionErrors` (default: `false`). Indicates whether to watch files +that don't have read permissions if possible. If watching fails due to `EPERM` +or `EACCES` with this set to `true`, the errors will be suppressed silently. +* `atomic` (default: `true` if `useFsEvents` and `usePolling` are `false`). +Automatically filters out artifacts that occur when using editors that use +"atomic writes" instead of writing directly to the source file. If a file is +re-added within 100 ms of being deleted, Chokidar emits a `change` event +rather than `unlink` then `add`. If the default of 100 ms does not work well +for you, you can override it by setting `atomic` to a custom value, in +milliseconds. + +### Methods & Events + +`chokidar.watch()` produces an instance of `FSWatcher`. Methods of `FSWatcher`: + +* `.add(path / paths)`: Add files, directories, or glob patterns for tracking. +Takes an array of strings or just one string. +* `.on(event, callback)`: Listen for an FS event. +Available events: `add`, `addDir`, `change`, `unlink`, `unlinkDir`, `ready`, +`raw`, `error`. +Additionally `all` is available which gets emitted with the underlying event +name and path for every event other than `ready`, `raw`, and `error`. `raw` is internal, use it carefully. +* `.unwatch(path / paths)`: Stop watching files, directories, or glob patterns. +Takes an array of strings or just one string. +* `.close()`: **async** Removes all listeners from watched files. Asynchronous, returns Promise. Use with `await` to ensure bugs don't happen. +* `.getWatched()`: Returns an object representing all the paths on the file +system being watched by this `FSWatcher` instance. The object's keys are all the +directories (using absolute paths unless the `cwd` option was used), and the +values are arrays of the names of the items contained in each directory. + +## CLI + +If you need a CLI interface for your file watching, check out +[chokidar-cli](https://github.com/open-cli-tools/chokidar-cli), allowing you to +execute a command on each change, or get a stdio stream of change events. + +## Install Troubleshooting + +* `npm WARN optional dep failed, continuing fsevents@n.n.n` + * This message is normal part of how `npm` handles optional dependencies and is + not indicative of a problem. Even if accompanied by other related error messages, + Chokidar should function properly. + +* `TypeError: fsevents is not a constructor` + * Update chokidar by doing `rm -rf node_modules package-lock.json yarn.lock && npm install`, or update your dependency that uses chokidar. + +* Chokidar is producing `ENOSP` error on Linux, like this: + * `bash: cannot set terminal process group (-1): Inappropriate ioctl for device bash: no job control in this shell` + `Error: watch /home/ ENOSPC` + * This means Chokidar ran out of file handles and you'll need to increase their count by executing the following command in Terminal: + `echo fs.inotify.max_user_watches=524288 | sudo tee -a /etc/sysctl.conf && sudo sysctl -p` + +## Changelog + +For more detailed changelog, see [`full_changelog.md`](.github/full_changelog.md). +- **v3.5 (Jan 6, 2021):** Support for ARM Macs with Apple Silicon.

Since the value of a cookie +has a limited character set (and must be a simple string), this function can be used to decode +a previously-encoded cookie value into a JavaScript string or other object. + +The default function is the global `decodeURIComponent`, which will decode any URL-encoded +sequences into their byte representations. + +**note** if an error is thrown from this function, the original, non-decoded cookie value will +be returned as the cookie's value. + +### cookie.serialize(name, value, options) + +Serialize a cookie name-value pair into a `Set-Cookie` header string. The `name` argument is the +name for the cookie, the `value` argument is the value to set the cookie to, and the `options` +argument is an optional object containing additional serialization options. + +```js +var setCookie = cookie.serialize('foo', 'bar'); +// foo=bar +``` + +#### Options + +`cookie.serialize` accepts these properties in the options object. + +##### domain + +Specifies the value for the [`Domain` `Set-Cookie` attribute][rfc-6265-5.2.3]. By default, no +domain is set, and most clients will consider the cookie to apply to only the current domain. + +##### encode + +Specifies a function that will be used to encode a cookie's value. Since value of a cookie +has a limited character set (and must be a simple string), this function can be used to encode +a value into a string suited for a cookie's value. + +The default function is the global `encodeURIComponent`, which will encode a JavaScript string +into UTF-8 byte sequences and then URL-encode any that fall outside of the cookie range. + +##### expires + +Specifies the `Date` object to be the value for the [`Expires` `Set-Cookie` attribute][rfc-6265-5.2.1]. +By default, no expiration is set, and most clients will consider this a "non-persistent cookie" and +will delete it on a condition like exiting a web browser application. + +**note** the [cookie storage model specification][rfc-6265-5.3] states that if both `expires` and +`maxAge` are set, then `maxAge` takes precedence, but it is possible not all clients by obey this, +so if both are set, they should point to the same date and time. + +##### httpOnly + +Specifies the `boolean` value for the [`HttpOnly` `Set-Cookie` attribute][rfc-6265-5.2.6]. When truthy, +the `HttpOnly` attribute is set, otherwise it is not. By default, the `HttpOnly` attribute is not set. + +**note** be careful when setting this to `true`, as compliant clients will not allow client-side +JavaScript to see the cookie in `document.cookie`. + +##### maxAge + +Specifies the `number` (in seconds) to be the value for the [`Max-Age` `Set-Cookie` attribute][rfc-6265-5.2.2]. +The given number will be converted to an integer by rounding down. By default, no maximum age is set. + +**note** the [cookie storage model specification][rfc-6265-5.3] states that if both `expires` and +`maxAge` are set, then `maxAge` takes precedence, but it is possible not all clients by obey this, +so if both are set, they should point to the same date and time. + +##### partitioned + +Specifies the `boolean` value for the [`Partitioned` `Set-Cookie`](rfc-cutler-httpbis-partitioned-cookies) +attribute. When truthy, the `Partitioned` attribute is set, otherwise it is not. By default, the +`Partitioned` attribute is not set. + +**note** This is an attribute that has not yet been fully standardized, and may change in the future. +This also means many clients may ignore this attribute until they understand it. + +More information about can be found in [the proposal](https://github.com/privacycg/CHIPS). + +##### path + +Specifies the value for the [`Path` `Set-Cookie` attribute][rfc-6265-5.2.4]. By default, the path +is considered the ["default path"][rfc-6265-5.1.4]. + +##### priority + +Specifies the `string` to be the value for the [`Priority` `Set-Cookie` attribute][rfc-west-cookie-priority-00-4.1]. + + - `'low'` will set the `Priority` attribute to `Low`. + - `'medium'` will set the `Priority` attribute to `Medium`, the default priority when not set. + - `'high'` will set the `Priority` attribute to `High`. + +More information about the different priority levels can be found in +[the specification][rfc-west-cookie-priority-00-4.1]. + +**note** This is an attribute that has not yet been fully standardized, and may change in the future. +This also means many clients may ignore this attribute until they understand it. + +##### sameSite + +Specifies the `boolean` or `string` to be the value for the [`SameSite` `Set-Cookie` attribute][rfc-6265bis-09-5.4.7]. + + - `true` will set the `SameSite` attribute to `Strict` for strict same site enforcement. + - `false` will not set the `SameSite` attribute. + - `'lax'` will set the `SameSite` attribute to `Lax` for lax same site enforcement. + - `'none'` will set the `SameSite` attribute to `None` for an explicit cross-site cookie. + - `'strict'` will set the `SameSite` attribute to `Strict` for strict same site enforcement. + +More information about the different enforcement levels can be found in +[the specification][rfc-6265bis-09-5.4.7]. + +**note** This is an attribute that has not yet been fully standardized, and may change in the future. +This also means many clients may ignore this attribute until they understand it. + +##### secure + +Specifies the `boolean` value for the [`Secure` `Set-Cookie` attribute][rfc-6265-5.2.5].

+[![Windows Build][appveyor-image]][appveyor-url] +[![Coverage Status][coveralls-image]][coveralls-url] + +Deprecate all the things + +> With great modules comes great responsibility; mark things deprecated! + +## Install + +This module is installed directly using `npm`: + +```sh +$ npm install depd +``` + +This module can also be bundled with systems like +[Browserify](http://browserify.org/) or [webpack](https://webpack.github.io/), +though by default this module will alter it's API to no longer display or +track deprecations. + +## API + + + +```js +var deprecate = require('depd')('my-module') +``` + +This library allows you to display deprecation messages to your users. +This library goes above and beyond with deprecation warnings by +introspection of the call stack (but only the bits that it is interested +in). + +Instead of just warning on the first invocation of a deprecated +function and never again, this module will warn on the first invocation +of a deprecated function per unique call site, making it ideal to alert +users of all deprecated uses across the code base, rather than just +whatever happens to execute first. + +The deprecation warnings from this module also include the file and line +information for the call into the module that the deprecated function was +in. + +**NOTE** this library has a similar interface to the `debug` module, and +this module uses the calling file to get the boundary for the call stacks, +so you should always create a new `deprecate` object in each file and not +within some central file. + +### depd(namespace) + +Create a new deprecate function that uses the given namespace name in the +messages and will display the call site prior to the stack entering the +file this function was called from. It is highly suggested you use the +name of your module as the namespace. + +### deprecate(message) + +Call this function from deprecated code to display a deprecation message. +This message will appear once per unique caller site. Caller site is the +first call site in the stack in a different file from the caller of this +function. + +If the message is omitted, a message is generated for you based on the site +of the `deprecate()` call and will display the name of the function called, +similar to the name displayed in a stack trace. + +### deprecate.function(fn, message) + +Call this function to wrap a given function in a deprecation message on any +call to the function. An optional message can be supplied to provide a custom +message. + +### deprecate.property(obj, prop, message) + +Call this function to wrap a given property on object in a deprecation message +on any accessing or setting of the property. An optional message can be supplied +to provide a custom message. + +The method must be called on the object where the property belongs (not +inherited from the prototype). + +If the property is a data descriptor, it will be converted to an accessor +descriptor in order to display the deprecation message. + +### process.on('deprecation', fn) + +This module will allow easy capturing of deprecation errors by emitting the +errors as the type "deprecation" on the global `process`. If there are no +listeners for this type, the errors are written to STDERR as normal, but if +there are any listeners, nothing will be written to STDERR and instead only +emitted. From there, you can write the errors in a different format or to a +logging source. + +The error represents the deprecation and is emitted only once with the same +rules as writing to STDERR. The error has the following properties: + + - `message` - This is the message given by the library + - `name` - This is always `'DeprecationError'` + - `namespace` - This is the namespace the deprecation came from + - `stack` - This is the stack of the call to the deprecated thing + +Example `error.stack` output: + +``` +DeprecationError: my-cool-module deprecated oldfunction + at Object. ([eval]-wrapper:6:22) + at Module._compile (module.js:456:26) + at evalScript (node.js:532:25) + at startup (node.js:80:7) + at node.js:902:3 +``` + +### process.env.NO_DEPRECATION + +As a user of modules that are deprecated, the environment variable `NO_DEPRECATION` +is provided as a quick solution to silencing deprecation warnings from being +output. The format of this is similar to that of `DEBUG`: + +```sh +$ NO_DEPRECATION=my-module,othermod node app.js +``` + +This will suppress deprecations from being output for "my-module" and "othermod". +The value is a list of comma-separated namespaces. To suppress every warning +across all namespaces, use the value `*` for a namespace. + +Providing the argument `--no-deprecation` to the `node` executable will suppress +all deprecations (only available in Node.js 0.8 or higher). + +**NOTE** This will not suppress the deperecations given to any "deprecation" +event listeners, just the output to STDERR. + +### process.env.TRACE_DEPRECATION + +As a user of modules that are deprecated, the environment variable `TRACE_DEPRECATION` +is provided as a solution to getting more detailed location information in deprecation +warnings by including the entire stack trace. The format of this is the same as +`NO_DEPRECATION`: + +```sh +$ TRACE_DEPRECATION=my-module,othermod node app.js +``` + +This will include stack traces for deprecations being output for "my-module" and +"othermod". The value is a list of comma-separated namespaces. To trace every +warning across all namespaces, use the value `*` for a namespace. + +Providing the argument `--trace-deprecation` to the `node` executable will trace +all deprecations (only available in Node.js 0.8 or higher). + +**NOTE** This will not trace the deperecations silenced by `NO_DEPRECATION`. + +## Display + +![message](files/message.png) + +When a user calls a function in your library that you mark deprecated, they +will see the following written to STDERR (in the given colors, similar colors +and layout to the `debug` module): + +``` +bright cyan bright yellow +| | reset cyan +| | | | +▼ ▼ ▼ ▼ +my-cool-module deprecated oldfunction [eval]-wrapper:6:22 +▲ ▲ ▲ ▲ +| | | | +namespace | | location of mycoolmod.oldfunction() call + | deprecation message + the word "deprecated" +``` + +If the user redirects their STDERR to a file or somewhere that does not support +colors, they see (similar layout to the `debug` module): + +``` +Sun, 15 Jun 2014 05:21:37 GMT my-cool-module deprecated oldfunction at [eval]-wrapper:6:22 +▲ ▲ ▲ ▲ ▲ +| | | | | +timestamp of message namespace | | location of mycoolmod.oldfunction() call + | deprecation message + the word "deprecated" +``` + +## Examples + +### Deprecating all calls to a function + +This will display a deprecated message about "oldfunction" being deprecated +from "my-module" on STDERR. + +```js +var deprecate = require('depd')('my-cool-module') + +// message automatically derived from function name +// Object.oldfunction +exports.oldfunction = deprecate.function(function oldfunction () { + // all calls to function are deprecated +}) + +// specific message +exports.oldfunction = deprecate.function(function () { + // all calls to function are deprecated +}, 'oldfunction') +``` + +### Conditionally deprecating a function call + +This will display a deprecated message about "weirdfunction" being deprecated +from "my-module" on STDERR when called with less than 2 arguments. + +```js +var deprecate = require('depd')('my-cool-module') + +exports.weirdfunction = function () { + if (arguments.length < 2) { + // calls with 0 or 1 args are deprecated + deprecate('weirdfunction args < 2') + } +} +``` + +When calling `deprecate` as a function, the warning is counted per call site +within your own module, so you can display different deprecations depending +on different situations and the users will still get all the warnings: + +```js +var deprecate = require('depd')('my-cool-module') + +exports.weirdfunction = function () { + if (arguments.length < 2) { + // calls with 0 or 1 args are deprecated + deprecate('weirdfunction args < 2') + } else if (typeof arguments[0] !== 'string') { + // calls with non-string first argument are deprecated + deprecate('weirdfunction non-string first arg') + } +} +``` + +### Deprecating property access + +This will display a deprecated message about "oldprop" being deprecated +from "my-module" on STDERR when accessed. A deprecation will be displayed +when setting the value and when getting the value. + +```js +var deprecate = require('depd')('my-cool-module') + +exports.oldprop = 'something' + +// message

+This is a [Node.js](https://nodejs.org/en/) module available through the +[npm registry](https://www.npmjs.com/). Installation is done using the +[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally): + +``` +$ npm install fresh +``` + +## API + + + +```js +var fresh = require('fresh') +``` + +### fresh(reqHeaders, resHeaders) + +Check freshness of the response using request and response headers. + +When the response is still "fresh" in the client's cache `true` is +returned, otherwise `false` is returned to indicate that the client +cache is now stale and the full response should be sent. + +When a client sends the `Cache-Control: no-cache` request header to +indicate an end-to-end reload request, this module will return `false` +to make handling these requests transparent. + +## Known Issues + +This module is designed to only follow the HTTP specifications, not +to work-around all kinda of client bugs (especially since this module +typically does not recieve enough information to understand what the +client actually is). + +There is a known issue that in certain versions of Safari, Safari +will incorrectly make a request that allows this module to validate +freshness of the resource even when Safari does not have a +representation of the resource in the cache. The module +[jumanji](https://www.npmjs.com/package/jumanji) can be used in +an Express application to work-around this issue and also provides +links to further reading on this Safari bug. + +## Example + +### API usage + + + +```js +var reqHeaders = { 'if-none-match': '"foo"' } +var resHeaders = { 'etag': '"bar"' } +fresh(reqHeaders, resHeaders) +// => false + +var reqHeaders = { 'if-none-match': '"foo"' } +var resHeaders = { 'etag': '"foo"' } +fresh(reqHeaders, resHeaders) +// => true +``` + +### Using with Node.js http server + +```js +var fresh = require('fresh') +var http = require('http') + +var server = http.createServer(function (req, res) { + // perform server logic + // ... including adding ETag / Last-Modified response headers + + if (isFresh(req, res)) { + // client has a fresh copy of resource + res.statusCode = 304 + res.end() + return + } + + // send the resource + res.statusCode = 200 + res.end('hello, world!') +}) + +function isFresh (req, res) { + return fresh(req.headers, { + 'etag': res.getHeader('ETag'), + 'last-modified': res.getHeader('Last-Modified') + }) +} + +server.listen(3000) +``` + +## License + +[MIT](LICENSE) + +[npm-image]:

If a path with backslashes +is provided anyway, for simple cases, glob-parent will replace the path +separator for you and return the non-glob parent path (now with +forward-slashes, which are still valid as Windows path separators). + +This cannot be used in conjunction with escape characters. + +```js +// BAD +globParent('C:\\Program Files \\(x86\\)\\*.ext') // 'C:/Program Files /(x86/)' + +// GOOD +globParent('C:/Program Files\\(x86\\)/*.ext') // 'C:/Program Files (x86)' +``` + +If you are using escape characters for a pattern without path parts (i.e. +relative to `cwd`), prefix with `./` to avoid confusing glob-parent. + +```js +// BAD +globParent('foo \\[bar]') // 'foo ' +globParent('foo \\[bar]*') // 'foo ' + +// GOOD +globParent('./foo \\[bar]') // 'foo [bar]' +globParent('./foo \\[bar]*') // '.' +``` + +## License + +ISC + +[expand-braces]: https://github.com/jonschlinkert/expand-braces +[expand-brackets]: https://github.com/jonschlinkert/expand-brackets + +[downloads-image]: https://img.shields.io/npm/dm/glob-parent.svg +[npm-url]: https://www.npmjs.com/package/glob-parent +[npm-image]: https://img.shields.io/npm/v/glob-parent.svg + +[azure-pipelines-url]: https://dev.azure.com/gulpjs/gulp/_build/latest?definitionId=2&branchName=master +[azure-pipelines-image]: https://dev.azure.com/gulpjs/gulp/_apis/build/status/glob-parent?branchName=master + +[travis-url]: https://travis-ci.org/gulpjs/glob-parent +[travis-image]: https://img.shields.io/travis/gulpjs/glob-parent.svg?label=travis-ci + +[appveyor-url]: https://ci.appveyor.com/project/gulpjs/glob-parent +[appveyor-image]: https://img.shields.io/appveyor/ci/gulpjs/glob-parent.svg?label=appveyor + +[coveralls-url]: https://coveralls.io/r/gulpjs/glob-parent +[coveralls-image]: https://img.shields.io/coveralls/gulpjs/glob-parent/master.svg + +[gitter-url]: https://gitter.im/gulpjs/gulp +[gitter-image]: https://badges.gitter.im/gulpjs/gulp.svg diff --git a/Week_4/node_modules/glob-parent/index.js b/Week_4/node_modules/glob-parent/index.js new file mode 100644 index 0000000..09e257e --- /dev/null +++ b/Week_4/node_modules/glob-parent/index.js @@ -0,0 +1,42 @@ +'use strict';

Use `addBOM: false` to override. + +## Other notes + +When decoding, be sure to supply a Buffer to decode() method, otherwise [bad things usually happen](https://github.com/ashtuchkin/iconv-lite/wiki/Use-Buffers-when-decoding). +Untranslatable characters are set to � or ?.

It runs on both CommonJS runtimes +(e.g. [nodejs]) and in a web browser. + +ipaddr.js allows you to verify and parse string representation of an IP +address, match it against a CIDR range or range list, determine if it falls +into some reserved ranges (examples include loopback and private ranges), +and convert between IPv4 and IPv4-mapped IPv6 addresses. + +[nodejs]: http://nodejs.org + +## Installation + +`npm install ipaddr.js` + +or + +`bower install ipaddr.js` + +## API + +ipaddr.js defines one object in the global scope: `ipaddr`. In CommonJS, +it is exported from the module: + +```js +var ipaddr = require('ipaddr.js'); +``` + +The API consists of several global methods and two classes: ipaddr.IPv6 and ipaddr.IPv4. + +### Global methods + +There are three global methods defined: `ipaddr.isValid`, `ipaddr.parse` and +`ipaddr.process`. All of them receive a string as a single parameter. + +The `ipaddr.isValid` method returns `true` if the address is a valid IPv4 or +IPv6 address, and `false` otherwise. It does not throw any exceptions. + +The `ipaddr.parse` method returns an object representing the IP address, +or throws an `Error` if the passed string is not a valid representation of an +IP address. + +The `ipaddr.process` method works just like the `ipaddr.parse` one, but it +automatically converts IPv4-mapped IPv6 addresses to their IPv4 counterparts +before returning. It is useful when you have a Node.js instance listening +on an IPv6 socket, and the `net.ivp6.bindv6only` sysctl parameter (or its +equivalent on non-Linux OS) is set to 0. In this case, you can accept IPv4 +connections on your IPv6-only socket, but the remote address will be mangled. +Use `ipaddr.process` method to automatically demangle it. + +### Object representation + +Parsing methods return an object which descends from `ipaddr.IPv6` or +`ipaddr.IPv4`. These objects share some properties, but most of them differ. + +#### Shared properties + +One can determine the type of address by calling `addr.kind()`. It will return +either `"ipv6"` or `"ipv4"`. + +An address can be converted back to its string representation with `addr.toString()`. +Note that this method: + * does not return the original string used to create the object (in fact, there is + no way of getting that string) + * returns a compact representation (when it is applicable) + +A `match(range, bits)` method can be used to check if the address falls into a +certain CIDR range. +Note that an address can be (obviously) matched only against an address of the same type. + +For example: + +```js +var addr = ipaddr.parse("2001:db8:1234::1"); +var range = ipaddr.parse("2001:db8::"); + +addr.match(range, 32); // => true +``` + +Alternatively, `match` can also be called as `match([range, bits])`. In this way, +it can be used together with the `parseCIDR(string)` method, which parses an IP +address together with a CIDR range. + +For example: + +```js +var addr = ipaddr.parse("2001:db8:1234::1"); + +addr.match(ipaddr.parseCIDR("2001:db8::/32")); // => true +``` + +A `range()` method returns one of predefined names for several special ranges defined +by IP protocols. The exact names (and their respective CIDR ranges) can be looked up +in the source: [IPv6 ranges] and [IPv4 ranges]. Some common ones include `"unicast"` +(the default one) and `"reserved"`. + +You can match against your own range list by using +`ipaddr.subnetMatch(address, rangeList, defaultName)` method. It can work with a mix of IPv6 or IPv4 addresses, and accepts a name-to-subnet map as the range list. For example: + +```js +var rangeList = { + documentationOnly: [ ipaddr.parse('2001:db8::'), 32 ], + tunnelProviders: [ + [ ipaddr.parse('2001:470::'), 32 ], // he.net + [ ipaddr.parse('2001:5c0::'), 32 ] // freenet6 + ] +}; +ipaddr.subnetMatch(ipaddr.parse('2001:470:8:66::1'), rangeList, 'unknown'); // => "tunnelProviders" +``` + +The addresses can be converted to their byte representation with `toByteArray()`. +(Actually, JavaScript mostly does not know about byte buffers. They are emulated with +arrays of numbers, each in range of 0..255.) + +```js +var bytes = ipaddr.parse('2a00:1450:8007::68').toByteArray(); // ipv6.google.com +bytes // => [42, 0x00, 0x14, 0x50, 0x80, 0x07, 0x00, , 0x00, 0x68 ] +``` + +The `ipaddr.IPv4` and `ipaddr.IPv6` objects have some methods defined, too. All of them +have the same interface for both protocols, and are similar to global methods. + +`ipaddr.IPvX.isValid(string)` can be used to check if the string is a valid address +for particular protocol, and `ipaddr.IPvX.parse(string)` is the error-throwing parser. + +`ipaddr.IPvX.isValid(string)` uses the same format for parsing as the POSIX `inet_ntoa` function, which accepts unusual formats like `0xc0.168.1.1` or `0x10000000`. The function `ipaddr.IPv4.isValidFourPartDecimal(string)` validates the IPv4 address and also ensures that it is written in four-part decimal format. + +[IPv6 ranges]: https://github.com/whitequark/ipaddr.js/blob/master/src/ipaddr.coffee#L186 +[IPv4 ranges]: https://github.com/whitequark/ipaddr.js/blob/master/src/ipaddr.coffee#L71 + +#### IPv6 properties + +Sometimes you will want to convert IPv6 not to a compact string representation (with +the `::` substitution); the `toNormalizedString()` method will return an address where +all zeroes are explicit. + +For example: + +```js +var addr = ipaddr.parse("2001:0db8::0001"); +addr.toString(); // => "2001:db8::1" +addr.toNormalizedString(); // => "2001:db8:0:0:0:0:0:1" +``` + +The `isIPv4MappedAddress()` method will return `true` if this address is an IPv4-mapped +one, and `toIPv4Address()` will return an IPv4 object address. + +To access the underlying binary representation of the address, use `addr.parts`. + +```js +var addr = ipaddr.parse("2001:db8:10::1234:DEAD"); +addr.parts // => [0x2001, 0xdb8, 0x10, 0, 0, 0, 0x1234, 0xdead] +``` + +A IPv6 zone index can be accessed via `addr.zoneId`: + +```js +var addr = ipaddr.parse("2001:db8::%eth0"); +addr.zoneId // => 'eth0' +``` + +#### IPv4 properties + +`toIPv4MappedAddress()` will return a corresponding IPv4-mapped IPv6 address. + +To access the underlying representation of the address, use `addr.octets`. + +```js +var addr = ipaddr.parse("192.168.1.1"); +addr.octets // => [192, 168, 1, 1] +``` + +`prefixLengthFromSubnetMask()` will return a CIDR prefix length for a valid IPv4 netmask or +null if the netmask is not valid. + +```js +ipaddr.IPv4.parse('255.255.255.240').prefixLengthFromSubnetMask() == 28 +ipaddr.IPv4.parse('255.192.164.0').prefixLengthFromSubnetMask() == null +``` + +`subnetMaskFromPrefixLength()` will return an IPv4 netmask for a valid CIDR prefix length. + +```js +ipaddr.IPv4.subnetMaskFromPrefixLength(24) == "255.255.255.0" +ipaddr.IPv4.subnetMaskFromPrefixLength(29) == "255.255.255.248" +``` + +`broadcastAddressFromCIDR()` will return the broadcast address for a given IPv4 interface and netmask in CIDR notation. +```js +ipaddr.IPv4.broadcastAddressFromCIDR("172.0.0.1/24") == "172.0.0.255" +``` +`networkAddressFromCIDR()` will return the network address for a given IPv4 interface and netmask in CIDR notation. +```js +ipaddr.IPv4.networkAddressFromCIDR("172.0.0.1/24") == "172.0.0.0" +``` + +#### Conversion + +IPv4 and IPv6 can be converted bidirectionally to and from network byte order (MSB) byte arrays. + +The `fromByteArray()` method will take an array and create an appropriate IPv4 or IPv6 object +if the input satisfies the requirements.

consists of a single, public JSON file and does not include any logic, +allowing it to remain as un-opinionated as possible with an API. +It aggregates data from the following sources: + +- http://www.iana.org/assignments/media-types/media-types.xhtml +- http://svn.apache.org/repos/asf/httpd/httpd/trunk/docs/conf/mime.types +- http://hg.nginx.org/nginx/raw-file/default/conf/mime.types +

This needs to be a [primary source](https://en.wikipedia.org/wiki/Primary_source); + links to type aggregating sites and Wikipedia are _not acceptable_. + +To update the build, run `npm run build`. + +### Adding Custom Media Types + +The best way to get new media types included in this library is to register +them with the IANA. The community registration procedure is outlined in +[RFC 6838 section 5](http://tools.ietf.org/html/rfc6838#section-5). Types +registered with the IANA are automatically pulled into this library. + +If that is not possible / feasible, they can be added directly here as a +"custom" type. To do this, it is required to have a primary source that +definitively lists the media type. If an extension is going to be listed as +associateed with this media type, the source must definitively link the +media type and extension as well. + +[ci-image]:

Each item in the row + corresponds to a single path-part. For example, the pattern + `{a,b/c}/d` would expand to a set of patterns like: + + [ [ a, d ] + , [ b, c, d ] ] + + If a portion of the pattern doesn't have any "magic" in it + (that is, it's something like `"foo"` rather than `fo*o?`), then it + will be left as a string rather than converted to a regular + expression. + +* `regexp` Created by the `makeRe` method. A single regular expression + expressing the entire pattern. This is useful in cases where you wish + to use the pattern somewhat like `fnmatch(3)` with `FNM_PATH` enabled. +* `negate` True if the pattern is negated. +* `comment` True if the pattern is a comment. +* `empty` True if the pattern is `""`. + +### Methods + +* `makeRe` Generate the `regexp` member if necessary, and return it. + Will return `false` if the pattern is invalid. +* `match(fname)` Return true if the filename matches the pattern, or + false otherwise. +* `matchOne(fileArray, patternArray, partial)` Take a `/`-split + filename, and match it against a single row in the `regExpSet`. This + method is mainly for internal use, but is exposed so that it can be + used by a glob-walker that needs to avoid excessive filesystem calls. + +All other methods are internal, and will be called as necessary. + +### minimatch(path, pattern, options) + +Main export. Tests a path against the pattern using the options. + +```javascript +var isJS = minimatch(file, "*.js", { matchBase: true }) +``` + +### minimatch.filter(pattern, options) + +Returns a function that tests its +supplied argument, suitable for use with `Array.filter`. Example: + +```javascript +var javascripts = fileList.filter(minimatch.filter("*.js", {matchBase: true})) +``` + +### minimatch.match(list, pattern, options) + +Match against the list of +files, in the style of fnmatch or glob. If nothing is matched, and +options.nonull is set, then return a list containing the pattern itself. + +```javascript +var javascripts = minimatch.match(fileList, "*.js", {matchBase: true})) +``` + +### minimatch.makeRe(pattern, options) + +Make a regular expression object from the pattern. + +## Options + +All options are `false` by default. + +### debug + +Dump a ton of stuff to stderr. + +### nobrace + +Do not expand `{a,b}` and `{1..3}` brace sets. + +### noglobstar + +Disable `**` matching against multiple folder names. + +### dot + +Allow patterns to match filenames starting with a period, even if +the pattern does not explicitly have a period in that spot. + +Note that by default, `a/**/b` will **not** match `a/.d/b`, unless `dot` +is set. + +### noext + +Disable "extglob" style patterns like `+(a|b)`. + +### nocase + +Perform a case-insensitive match. + +### nonull + +When a match is not found by `minimatch.match`, return a list containing +the pattern itself if this option is set. When not set, an empty list +is returned if there are no matches. + +### matchBase + +If set, then patterns without slashes will be matched +against the basename of the path if it contains slashes. For example, +`a?b` would match the path `/xyz/123/acb`, but not `/xyz/acb/123`. + +### nocomment + +Suppress the behavior of treating `#` at the start of a pattern as a +comment. + +### nonegate + +Suppress the behavior of treating a leading `!` character as negation. + +### flipNegate + +Returns from negate expressions the same as if they were not negated. +(Ie, true on a hit, false on a miss.) + +### partial + +Compare a partial path to a pattern. As long as the parts of the path that +are present are not contradicted by the pattern, it will be treated as a +match. This is useful in applications where you're walking through a +folder structure, and don't yet have the full path, but want to ensure that +you do not walk down paths that can never be a match. + +For example, + +```js +minimatch('/a/b', '/a/*/c/d', { partial: true }) // true, might be /a/b/c/d +minimatch('/a/b', '/**/d', { partial: true }) // true, might be /a/b/.../d +minimatch('/x/y/z', '/a/**/z', { partial: true }) // false, because x !== a +``` + +### allowWindowsEscape + +Windows path separator `\` is by default converted to `/`, which +prohibits the usage of `\` as a escape character. This flag skips that +behavior and allows using the escape character. + +## Comparisons to other fnmatch/glob implementations + +While strict compliance with the existing standards is a worthwhile +goal, some discrepancies exist between minimatch and other +implementations, and are intentional. + +If the pattern starts with a `!` character, then it is negated. Set the +`nonegate` flag to suppress this behavior, and treat leading `!` +characters normally. This is perhaps relevant if you wish to start the +pattern with a negative extglob pattern like `!(a|B)`. Multiple `!` +characters at the start of a pattern will negate the pattern multiple +times. + +If a pattern starts with `#`, then it is treated as a comment, and +will not match anything. Use `\#` to match a literal `#` at the +start of a line, or set the `nocomment` flag to suppress this behavior. + +The double-star character `**` is supported by default, unless the +`noglobstar` flag is set. This is supported in the manner of bsdglob +and bash 4.1, where `**` only has special significance if it is the only +thing in a path part. That is, `a/**/b` will match `a/x/y/b`, but +`a/**b` will not. + +If an escaped pattern has no matches, and the `nonull` flag is set, +then minimatch.match returns the pattern as-provided, rather than +interpreting the character escapes. For example, +`minimatch.match([], "\\*a\\?")` will return `"\\*a\\?"` rather than +`"*a?"`. This is akin to setting the `nullglob` option in bash, except +that it does not resolve escaped pattern characters. + +If brace expansion is not disabled, then it is performed before any +other interpretation of the glob pattern. Thus, a pattern like +`+(a|{b),c)}`, which would not be valid in bash or zsh, is expanded +**first** into the set of `+(a|b)` and `+(a|c)`, and those patterns are +checked for validity. Since those two are valid, matching proceeds. diff --git a/Week_4/node_modules/minimatch/minimatch.js b/Week_4/node_modules/minimatch/minimatch.js new file mode 100644 index 0000000..fda45ad --- /dev/null +++ b/Week_4/node_modules/minimatch/minimatch.js @@ -0,0 +1,947 @@ +module.exports = minimatch +minimatch.Minimatch = Minimatch + +var path = (function () { try { return require('path') } catch (e) {}}()) || { + sep: '/' +} +minimatch.sep = path.sep + +var GLOBSTAR = minimatch.GLOBSTAR = Minimatch.GLOBSTAR = {} +var expand = require('brace-expansion') + +var plTypes = { + '!': { open: '(?:(?!(?:', close: '))[^/]*?)'}, + '?': { open: '(?:', close: ')?' }, + '+': { open: '(?:', close: ')+' }, + '*': { open: '(?:', close: ')*' }, + '@': { open: '(?:', close: ')' } +} + +// any single thing other than / +// don't need to escape / when using new RegExp() +var qmark = '[^/]' + +// * => any number of characters +var star = qmark + '*?' + +// ** when dots are allowed.

+ Nodemon Logo +

+ +# nodemon + +nodemon is a tool that helps develop Node.js based applications by automatically restarting the node application when file changes in the directory are detected. + +nodemon does **not** require *any* additional changes to your code or method of development. nodemon is a replacement wrapper for `node`. To use `nodemon`, replace the word `node` on the command line when executing your script. + +[![NPM version](https://badge.fury.io/js/nodemon.svg)](https://npmjs.org/package/nodemon) +[![Backers on Open Collective](https://opencollective.com/nodemon/backers/badge.svg)](#backers) [![Sponsors on Open Collective](https://opencollective.com/nodemon/sponsors/badge.svg)](#sponsors) + +# Installation + +Either through cloning with git or by using [npm](http://npmjs.org) (the recommended way): + +```bash +npm install -g nodemon # or using yarn: yarn global add nodemon +``` + +And nodemon will be installed globally to your system path. + +You can also install nodemon as a development dependency: + +```bash +npm install --save-dev nodemon # or using yarn: yarn add nodemon -D +``` + +With a local installation, nodemon will not be available in your system path or you can't use it directly from the command line. Instead, the local installation of nodemon can be run by calling it from within an npm script (such as `npm start`) or using `npx nodemon`. + +# Usage + +nodemon wraps your application, so you can pass all the arguments you would normally pass to your app: + +```bash +nodemon [your node app] +``` + +For CLI options, use the `-h` (or `--help`) argument: + +```bash +nodemon -h +``` + +Using nodemon is simple, if my application accepted a host and port as the arguments, I would start it as so: + +```bash +nodemon ./server.js localhost 8080 +``` + +Any output from this script is prefixed with `[nodemon]`, otherwise all output from your application, errors included, will be echoed out as expected. + +You can also pass the `inspect` flag to node through the command line as you would normally: + +```bash +nodemon --inspect ./server.js 80 +``` + +If you have a `package.json` file for your app, you can omit the main script entirely and nodemon will read the `package.json` for the `main` property and use that value as the app ([ref](https://github.com/remy/nodemon/issues/14)). + +nodemon will also search for the `scripts.start` property in `package.json` (as of nodemon 1.1.x). + +Also check out the [FAQ](https://github.com/remy/nodemon/blob/master/faq.md) or [issues](https://github.com/remy/nodemon/issues) for nodemon. + +## Automatic re-running + +nodemon was originally written to restart hanging processes such as web servers, but now supports apps that cleanly exit. If your script exits cleanly, nodemon will continue to monitor the directory (or directories) and restart the script if there are any changes. + +## Manual restarting + +Whilst nodemon is running, if you need to manually restart your application, instead of stopping and restart nodemon, you can type `rs` with a carriage return, and nodemon will restart your process. + +## Config files + +nodemon supports local and global configuration files. These are usually named `nodemon.json` and can be located in the current working directory or in your home directory. An alternative local configuration file can be specified with the `--config ` option. + +The specificity is as follows, so that a command line argument will always override the config file settings: + +- command line arguments +- local config +- global config + +A config file can take any of the command line arguments as JSON key values, for example: + +```json +{ + "verbose": true, + "ignore": ["*.test.js", "**/fixtures/**"], + "execMap": { + "rb": "ruby", + "pde": "processing --sketch={{pwd}} --run" + } +} +``` + +The above `nodemon.json` file might be my global config so that I have support for ruby files and processing files, and I can run `nodemon demo.pde` and nodemon will automatically know how to run the script even though out of the box support for processing scripts. + +A further example of options can be seen in [sample-nodemon.md](https://github.com/remy/nodemon/blob/master/doc/sample-nodemon.md) + +### package.json + +If you want to keep all your package configurations in one place, nodemon supports using `package.json` for configuration. +Specify the config in the same format as you would for a config file but under `nodemonConfig` in the `package.json` file, for example, take the following `package.json`: + +```json +{ + "name": "nodemon", + "homepage": "http://nodemon.io", + "...": "... other standard package.json values", + "nodemonConfig": { + "ignore": ["**/test/**", "**/docs/**"], + "delay": 2500 + } +} +``` + +Note that if you specify a `--config` file or provide a local `nodemon.json` any `package.json` config is ignored. + +*This section needs better documentation, but for now you can also see `nodemon --help config` ([also here](https://github.com/remy/nodemon/blob/master/doc/cli/config.txt))*. + +## Using nodemon as a module + +Please see [doc/requireable.md](doc/requireable.md) + +## Using nodemon as child process + +Please see [doc/events.md](doc/events.md#Using_nodemon_as_child_process) + +## Running non-node scripts + +nodemon can also be used to execute and monitor other programs. nodemon will read the file extension of the script being run and monitor that extension instead of `.js` if there's no `nodemon.json`: + +```bash +nodemon --exec "python -v" ./app.py +``` + +Now nodemon will run `app.py` with python in verbose mode (note that if you're not passing args to the exec program, you don't need the quotes), and look for new or modified files with the `.py` extension. + +### Default executables + +Using the `nodemon.json` config file, you can define your own default executables using the `execMap` property. This is particularly useful if you're working with a language that isn't supported by default by nodemon. + +To add support for nodemon to know about the `.pl` extension (for Perl), the `nodemon.json` file would add: + +```json +{ + "execMap": { + "pl": "perl" + } +} +``` + +Now running the following, nodemon will know to use `perl` as the executable: + +```bash +nodemon script.pl +``` + +It's generally recommended to use the global `nodemon.json` to add your own `execMap` options. However, if there's a common default that's missing, this can be merged in to the project so that nodemon supports it by default, by changing [default.js](https://github.com/remy/nodemon/blob/master/lib/config/defaults.js) and sending a pull request. + +## Monitoring multiple directories + +By default nodemon monitors the current working directory. If you want to take control of that option, use the `--watch` option to add specific paths: + +```bash +nodemon --watch app --watch libs app/server.js +``` + +Now nodemon will only restart if there are changes in the `./app` or `./libs` directory. By default nodemon will traverse sub-directories, so there's no need in explicitly including sub-directories. + +Nodemon also supports unix globbing, e.g `--watch './lib/*'`. The globbing pattern must be quoted. For advanced globbing, [see `picomatch` documentation](https://github.com/micromatch/picomatch#advanced-globbing), the library that nodemon uses through `chokidar` (which in turn uses it through `anymatch`). + +## Specifying extension watch list + +By default, nodemon looks for files with the `.js`, `.mjs`, `.coffee`, `.litcoffee`, and `.json` extensions. If you use the `--exec` option and monitor `app.py` nodemon will monitor files with the extension of `.py`. However, you can specify your own list with the `-e` (or `--ext`) switch like so: + +```bash +nodemon -e js,pug +``` + +Now nodemon will restart on any changes to files in the directory (or subdirectories) with the extensions `.js`, `.pug`. + +## Ignoring files + +By default, nodemon will only restart when a `.js` JavaScript file changes. In some cases you will want to ignore some specific files, directories or file patterns, to prevent nodemon from prematurely restarting your application. + +This can be done via the command line: + +```bash +nodemon --ignore lib/ --ignore tests/ +``` + +Or specific files can be ignored: + +```bash +nodemon --ignore lib/app.js +``` + +Patterns can also be ignored (but be sure to quote the arguments): + +```bash +nodemon --ignore 'lib/*.js' +``` + +**Important** the ignore rules are patterns matched to the full absolute path, and this determines how many files are monitored. If using a wild card glob pattern, it needs to be used as `**` or omitted entirely. For example, `nodemon --ignore '**/test/**'` will work, whereas `--ignore '*/test/*'` will not. + +Note that by default, nodemon will ignore the `.git`, `node_modules`, `bower_components`, `.nyc_output`, `coverage` and `.sass-cache` directories and *add* your ignored patterns to the list. If you want to indeed watch a directory like `node_modules`, you need to [override the underlying default ignore rules](https://github.com/remy/nodemon/blob/master/faq.md#overriding-the-underlying-default-ignore-rules). + +## Application isn't restarting + +In some networked environments (such as a container running nodemon reading across a mounted drive), you will need to use the `legacyWatch: true` which enables Chokidar's polling. + +Via the CLI, use either `--legacy-watch` or `-L` for short: + +```bash +nodemon -L +``` + +Though this should be a last resort as it will poll every file it can find. + +## Delaying restarting + +In some situations, you may want to wait until a number of files have changed. The timeout before checking for new file changes is 1 second. If you're uploading a number of files and it's taking some number of seconds, this could cause your app to restart multiple times unnecessarily. + +To add an extra throttle, or delay restarting, use the `--delay` command: + +```bash +nodemon --delay 10 server.js +``` + +For more precision, milliseconds can be specified. Either as a float: + +```bash +nodemon --delay 2.5 server.js +``` + +Or using the time specifier (ms): + +```bash +nodemon --delay 2500ms server.js +``` + +The delay figure is number of seconds (or milliseconds, if specified) to delay before restarting. So nodemon will only restart your app the given number of seconds after the *last* file change. + +If you are setting this value in `nodemon.json`, the value will always be interpreted in milliseconds. E.g., the following are equivalent: + +```bash +nodemon --delay 2.5 + +{ + "delay": 2500 +} +``` + +## Gracefully reloading down your script + +It is possible to have nodemon send any signal that you specify to your application. + +```bash +nodemon --signal SIGHUP server.js +``` + +Your application can handle the signal as follows. + +```js +process.on("SIGHUP", function () { + reloadSomeConfiguration(); + process.kill(process.pid, "SIGTERM"); +}) +``` + +Please note that nodemon will send this signal to every process in the process tree. + +If you are using `cluster`, then each workers (as well as the master) will receive the signal. If you wish to terminate all workers on receiving a `SIGHUP`, a common pattern is to catch the `SIGHUP` in the master, and forward `SIGTERM` to all workers, while ensuring that all workers ignore `SIGHUP`. + +```js +if (cluster.isMaster) { + process.on("SIGHUP", function () { + for (const worker of Object.values(cluster.workers)) { + worker.process.kill("SIGTERM"); + } + }); +} else { + process.on("SIGHUP", function() {}) +} +``` + +## Controlling shutdown of your script + +nodemon sends a kill signal to your application when it sees a file update. If you need to clean up on shutdown inside your script you can capture the kill signal and handle it yourself. + +The following example will listen once for the `SIGUSR2` signal (used by nodemon to restart), run the clean up process and then kill itself for nodemon to continue control: + +```js +// important to use `on` and not `once` as nodemon can re-send the kill signal +process.on('SIGUSR2', function () { + gracefulShutdown(function () { + process.kill(process.pid, 'SIGTERM'); + }); +}); +``` + +Note that the `process.kill` is *only* called once your shutdown jobs are complete. Hat tip to [Benjie Gillam](http://www.benjiegillam.com/2011/08/node-js-clean-restart-and-faster-development-with-nodemon/) for writing this technique up. + +## Triggering events when nodemon state changes + +If you want growl like notifications when nodemon restarts or to trigger an action when an event happens, then you can either `require` nodemon or add event actions to your `nodemon.json` file. + +For example, to trigger a notification on a Mac when nodemon restarts, `nodemon.json` looks like this: + +```json +{ + "events": { + "restart": "osascript -e 'display notification \"app restarted\" with title \"nodemon\"'" + } +} +``` + +A full list of available events is listed on the [event states wiki](https://github.com/remy/nodemon/wiki/Events#states). Note that you can bind to both states and messages. + +## Pipe output to somewhere else + +```js +nodemon({ + script: ..., + stdout: false // important: this tells nodemon not to output to console +}).on('readable', function() { // the `readable` event indicates that data is ready to pick up + this.stdout.pipe(fs.createWriteStream('output.txt')); + this.stderr.pipe(fs.createWriteStream('err.txt')); +}); +``` + +## Using nodemon in your gulp workflow + +Check out the [gulp-nodemon](https://github.com/JacksonGariety/gulp-nodemon) plugin to integrate nodemon with the rest of your project's gulp workflow. + +## Using nodemon in your Grunt workflow + +Check out the [grunt-nodemon](https://github.com/ChrisWren/grunt-nodemon) plugin to integrate nodemon with the rest of your project's grunt workflow. + +## Pronunciation + +> nodemon, is it pronounced: node-mon, no-demon or node-e-mon (like pokémon)? + +Well...I've been asked this many times before. I like that I've been asked this before. There's been bets as to which one it actually is. + +The answer is simple, but possibly frustrating. I'm not saying (how I pronounce it).

You also _should_ install +the [`supports-color`](https://npmjs.org/supports-color) module alongside debug, +otherwise debug will only use a small handful of basic colors. + + + +#### Web Browser + +Colors are also enabled on "Web Inspectors" that understand the `%c` formatting +option. These are WebKit web inspectors, Firefox ([since version +31](https://hacks.mozilla.org/2014/05/editable-box-model-multiple-selection-sublime-text-keys-much-more-firefox-developer-tools-episode-31/)) +and the Firebug plugin for Firefox (any version). + + + + +## Millisecond diff + +When actively developing an application it can be useful to see when the time spent between one `debug()` call and the next. Suppose for example you invoke `debug()` before requesting a resource, and after as well, the "+NNNms" will show you how much time was spent between calls. + + + +When stdout is not a TTY, `Date#toISOString()` is used, making it more useful for logging the debug information as shown below: + + + + +## Conventions + +If you're using this in one or more of your libraries, you _should_ use the name of your library so that developers may toggle debugging as desired without guessing names. If you have more than one debuggers you _should_ prefix them with your library name and use ":" to separate features. For example "bodyParser" from Connect would then be "connect:bodyParser". If you append a "*" to the end of your name, it will always be enabled regardless of the setting of the DEBUG environment variable. You can then use it for normal output as well as debug output. + +## Wildcards + +The `*` character may be used as a wildcard. Suppose for example your library has +debuggers named "connect:bodyParser", "connect:compress", "connect:session", +instead of listing all three with +`DEBUG=connect:bodyParser,connect:compress,connect:session`, you may simply do +`DEBUG=connect:*`, or to run everything using this module simply use `DEBUG=*`. + +You can also exclude specific debuggers by prefixing them with a "-" character. +For example, `DEBUG=*,-connect:*` would include all debuggers except those +starting with "connect:". + +## Environment Variables + +When running through Node.js, you can set a few environment variables that will +change the behavior of the debug logging: + +| Name | Purpose | +|-----------|-------------------------------------------------| +| `DEBUG` | Enables/disables specific debugging namespaces. | +| `DEBUG_HIDE_DATE` | Hide date from debug output (non-TTY). | +| `DEBUG_COLORS`| Whether or not to use colors in the debug output. | +| `DEBUG_DEPTH` | Object inspection depth. | +| `DEBUG_SHOW_HIDDEN` | Shows hidden properties on inspected objects. | + + +__Note:__ The environment variables beginning with `DEBUG_` end up being +converted into an Options object that gets used with `%o`/`%O` formatters. +See the Node.js documentation for +[`util.inspect()`](https://nodejs.org/api/util.html#util_util_inspect_object_options) +for the complete list. + +## Formatters + +Debug uses [printf-style](https://wikipedia.org/wiki/Printf_format_string) formatting. +Below are the officially supported formatters: + +| Formatter | Representation | +|-----------|----------------| +| `%O` | Pretty-print an Object on multiple lines. | +| `%o` | Pretty-print an Object all on a single line. | +| `%s` | String. | +| `%d` | Number (both integer and float). | +| `%j` | JSON. Replaced with the string '[Circular]' if the argument contains circular references. | +| `%%` | Single percent sign ('%'). This does not consume an argument. | + + +### Custom formatters + +You can add custom formatters by extending the `debug.formatters` object. +For example, if you wanted to add support for rendering a Buffer as hex with +`%h`, you could do something like: + +```js +const createDebug = require('debug') +createDebug.formatters.h = (v) => { + return v.toString('hex') +} + +// …elsewhere +const debug = createDebug('foo') +debug('this is hex: %h', new Buffer('hello world')) +// foo this is hex: 68656c6c6f20776f726c6421 +0ms +``` + + +## Browser Support + +You can build a browser-ready script using [browserify](https://github.com/substack/node-browserify), +or just use the [browserify-as-a-service](https://wzrd.in/) [build](https://wzrd.in/standalone/debug@latest), +if you don't want to build it yourself. + +Debug's enable state is currently persisted by `localStorage`. +Consider the situation shown below where you have `worker:a` and `worker:b`, +and wish to debug both. You can enable this using `localStorage.debug`: + +```js +localStorage.debug = 'worker:*' +``` + +And then refresh the page. + +```js +a = debug('worker:a'); +b = debug('worker:b'); + +setInterval(function(){ + a('doing some work'); +}, 1000); + +setInterval(function(){ + b('doing some work'); +}, 1200); +``` + +In Chromium-based web browsers (e.g. Brave, Chrome, and Electron), the JavaScript console will—by default—only show messages logged by `debug` if the "Verbose" log level is _enabled_. + + + +## Output streams + + By default `debug` will log to stderr, however this can be configured per-namespace by overriding the `log` method: + +Example [_stdout.js_](./examples/node/stdout.js): + +```js +var debug = require('debug'); +var error = debug('app:error'); + +// by default stderr is used +error('goes to stderr!'); + +var log = debug('app:log'); +// set this namespace to log via console.log +log.log = console.log.bind(console); // don't forget to bind to console! +log('goes to stdout'); +error('still goes to stderr!'); + +// set all output to go via console.info +// overrides all per-namespace log settings +debug.log = console.info.bind(console); +error('now goes to stdout via console.info'); +log('still goes to stdout, but via console.info now'); +``` + +## Extend +You can simply extend debugger +```js +const log = require('debug')('auth'); + +//creates new debug instance with extended namespace +const logSign = log.extend('sign'); +const logLogin = log.extend('login'); + +log('hello'); // auth hello +logSign('hello'); //auth:sign hello +logLogin('hello'); //auth:login hello +``` + +## Set dynamically + +You can also enable debug dynamically by calling the `enable()` method : + +```js +let debug = require('debug'); + +console.log(1, debug.enabled('test')); + +debug.enable('test'); +console.log(2, debug.enabled('test')); + +debug.disable(); +console.log(3, debug.enabled('test')); + +``` + +print : +``` +1 false +2 true +3 false +``` + +Usage : +`enable(namespaces)` +`namespaces` can include modes separated by a colon and wildcards. + +Note that calling `enable()` completely overrides previously set DEBUG variable : + +``` +$ DEBUG=foo node -e 'var dbg = require("debug"); dbg.enable("bar"); console.log(dbg.enabled("foo"))' +=> false +``` + +`disable()` + +Will disable all namespaces. The functions returns the namespaces currently +enabled (and skipped). This can be useful if you want to disable debugging +temporarily without knowing what was enabled to begin with. + +For example: + +```js +let debug = require('debug'); +debug.enable('foo:*,-foo:bar'); +let namespaces = debug.disable(); +debug.enable(namespaces); +``` + +Note: There is no guarantee that the string will be identical to the initial +enable string, but semantically they will be identical. + +## Checking whether a debug target is enabled + +After you've created a debug instance, you can determine whether or not it is +enabled by checking the `enabled` property: + +```javascript +const debug = require('debug')('http'); + +if (debug.enabled) { + // do stuff... +} +``` + +You can also manually toggle this property to force the debug instance to be +enabled or disabled. + +## Usage in child processes + +Due to the way `debug` detects if the output is a TTY or not, colors are not shown in child processes when `stderr` is piped. A solution is to pass the `DEBUG_COLORS=1` environment variable to the child process. +For example: + +```javascript +worker = fork(WORKER_WRAP_PATH, [workerPath], { + stdio: [ + /* stdin: */ 0, + /* stdout: */ 'pipe', + /* stderr: */ 'pipe', + 'ipc', + ], + env: Object.assign({}, process.env, { + DEBUG_COLORS: 1 // without this settings, colors won't be shown + }), +}); + +worker.stderr.pipe(process.stderr, { end: false }); +``` + + +## Authors + + - TJ Holowaychuk + - Nathan Rajlich + - Andrew Rhyne + - Josh Junon + +## Backers + +Support us with a monthly donation and help us continue our activities.

This means if the `CONNECT` request contains a request entity, +the request will be considered "finished" even before it has been read. + +There is no such thing as a response object to a `CONNECT` request in +Node.js, so there is no support for one. + +### HTTP Upgrade request + +The meaning of the `Upgrade` header from RFC 7230, section 6.1: + +> The "Upgrade" header field is intended to provide a simple mechanism +> for transitioning from HTTP/1.1 to some other protocol on the same +> connection. + +In Node.js, these request objects come from the `'upgrade'` event on +the HTTP server. + +When this module is used on a HTTP request with an `Upgrade` header, the +request is considered "finished" immediately, **due to limitations in the +Node.js interface**. This means if the `Upgrade` request contains a request +entity, the request will be considered "finished" even before it has been +read. + +There is no such thing as a response object to a `Upgrade` request in +Node.js, so there is no support for one. + +## Example + +The following code ensures that file descriptors are always closed +once the response finishes. + +```js +var destroy = require('destroy') +var fs = require('fs') +var http = require('http') +var onFinished = require('on-finished') + +http.createServer(function onRequest (req, res) { + var stream = fs.createReadStream('package.json') + stream.pipe(res) + onFinished(res, function () { + destroy(stream) + }) +}) +``` + +## License + +[MIT](LICENSE) + +[ci-image]:

+Blazing fast and accurate glob matcher written in JavaScript.
+No dependencies and full support for standard and extended Bash glob features, including braces, extglobs, POSIX brackets, and regular expressions. +

+ +
+
+ +## Why picomatch? + +* **Lightweight** - No dependencies +* **Minimal** - Tiny API surface. Main export is a function that takes a glob pattern and returns a matcher function. +* **Fast** - Loads in about 2ms (that's several times faster than a [single frame of a HD movie](http://www.endmemo.com/sconvert/framespersecondframespermillisecond.php) at 60fps) +* **Performant** - Use the returned matcher function to speed up repeat matching (like when watching files) +* **Accurate matching** - Using wildcards (`*` and `?`), globstars (`**`) for nested directories, [advanced globbing](#advanced-globbing) with extglobs, braces, and POSIX brackets, and support for escaping special characters with `\` or quotes. +* **Well tested** - Thousands of unit tests + +See the [library comparison](#library-comparisons) to other libraries. + +

+ +## Usage + +The main export is a function that takes a glob pattern and an options object and returns a function for matching strings. + +```js +const pm = require('picomatch'); +const isMatch = pm('*.js'); + +console.log(isMatch('abcd')); //=> false +console.log(isMatch('a.js')); //=> true +console.log(isMatch('a.md')); //=> false +console.log(isMatch('a/b.js')); //=> false +``` + +
+ +## API + +### [picomatch](lib/picomatch.js#L32) + +Creates a matcher function from one or more glob patterns. The returned function takes a string to match as its first argument, and returns true if the string is a match.

+ +## Options + +### Picomatch options + +The following options may be used with the main `picomatch()` function or any of the methods on the picomatch API. + +| **Option** | **Type** | **Default value** | **Description** | +| --- | --- | --- | --- | +| `basename` | `boolean` | `false` | If set, then patterns without slashes will be matched against the basename of the path if it contains slashes. For example, `a?b` would match the path `/xyz/123/acb`, but not `/xyz/acb/123`. | +| `bash` | `boolean` | `false` | Follow bash matching rules more strictly - disallows backslashes as escape characters, and treats single stars as globstars (`**`). | +| `capture` | `boolean` | `undefined` | Return regex matches in supporting methods. | +| `contains` | `boolean` | `undefined` | Allows glob to match any part of the given string(s). | +| `cwd` | `string` | `process.cwd()` | Current working directory. Used by `picomatch.split()` | +| `debug` | `boolean` | `undefined` | Debug regular expressions when an error is thrown. | +| `dot` | `boolean` | `false` | Enable dotfile matching. By default, dotfiles are ignored unless a `.` is explicitly defined in the pattern, or `options.dot` is true | +| `expandRange` | `function` | `undefined` | Custom function for expanding ranges in brace patterns, such as `{a..z}`. The function receives the range values as two arguments, and it must return a string to be used in the generated regex. It's recommended that returned strings be wrapped in parentheses. | +| `failglob` | `boolean` | `false` | Throws an error if no matches are found. Based on the bash option of the same name. | +| `fastpaths` | `boolean` | `true` | To speed up processing, full parsing is skipped for a handful common glob patterns. Disable this behavior by setting this option to `false`. | +| `flags` | `string` | `undefined` | Regex flags to use in the generated regex. If defined, the `nocase` option will be overridden. | +| [format](#optionsformat) | `function` | `undefined` | Custom function for formatting the returned string. This is useful for removing leading slashes, converting Windows paths to Posix paths, etc. | +| `ignore` | `array\|string` | `undefined` | One or more glob patterns for excluding strings that should not be matched from the result. | +| `keepQuotes` | `boolean` | `false` | Retain quotes in the generated regex, since quotes may also be used as an alternative to backslashes. | +| `literalBrackets` | `boolean` | `undefined` | When `true`, brackets in the glob pattern will be escaped so that only literal brackets will be matched. | +| `matchBase` | `boolean` | `false` | Alias for `basename` | +| `maxLength` | `boolean` | `65536` | Limit the max length of the input string. An error is thrown if the input string is longer than this value. | +| `nobrace` | `boolean` | `false` | Disable brace matching, so that `{a,b}` and `{1..3}` would be treated as literal characters. | +| `nobracket` | `boolean` | `undefined` | Disable matching with regex brackets. | +| `nocase` | `boolean` | `false` | Make matching case-insensitive. Equivalent to the regex `i` flag. Note that this option is overridden by the `flags` option. | +| `nodupes` | `boolean` | `true` | Deprecated, use `nounique` instead. This option will be removed in a future major release. By default duplicates are removed. Disable uniquification by setting this option to false. | +| `noext` | `boolean` | `false` | Alias for `noextglob` | +| `noextglob` | `boolean` | `false` | Disable support for matching with extglobs (like `+(a\|b)`) | +| `noglobstar` | `boolean` | `false` | Disable support for matching nested directories with globstars (`**`) | +| `nonegate` | `boolean` | `false` | Disable support for negating with leading `!` | +| `noquantifiers` | `boolean` | `false` | Disable support for regex quantifiers (like `a{1,2}`) and treat them as brace patterns to be expanded. | +| [onIgnore](#optionsonIgnore) | `function` | `undefined` | Function to be called on ignored items. | +| [onMatch](#optionsonMatch) | `function` | `undefined` | Function to be called on matched items. | +| [onResult](#optionsonResult) | `function` | `undefined` | Function to be called on all items, regardless of whether or not they are matched or ignored. | +| `posix` | `boolean` | `false` | Support POSIX character classes ("posix brackets"). | +| `posixSlashes` | `boolean` | `undefined` | Convert all slashes in file paths to forward slashes. This does not convert slashes in the glob pattern itself | +| `prepend` | `boolean` | `undefined` | String to prepend to the generated regex used for matching. | +| `regex` | `boolean` | `false` | Use regular expression rules for `+` (instead of matching literal `+`), and for stars that follow closing parentheses or brackets (as in `)*` and `]*`). | +| `strictBrackets` | `boolean` | `undefined` | Throw an error if brackets, braces, or parens are imbalanced. | +| `strictSlashes` | `boolean` | `undefined` | When true, picomatch won't match trailing slashes with single stars. | +| `unescape` | `boolean` | `undefined` | Remove backslashes preceding escaped characters in the glob pattern. By default, backslashes are retained. | +| `unixify` | `boolean` | `undefined` | Alias for `posixSlashes`, for backwards compatibility. | + +picomatch has automatic detection for regex positive and negative lookbehinds. If the pattern contains a negative lookbehind, you must be using Node.js >= 8.10 or else picomatch will throw an error. + +### Scan Options + +In addition to the main [picomatch options](#picomatch-options), the following options may also be used with the [.scan](#scan) method. + +| **Option** | **Type** | **Default value** | **Description** | +| --- | --- | --- | --- | +| `tokens` | `boolean` | `false` | When `true`, the returned object will include an array of tokens (objects), representing each path "segment" in the scanned glob pattern | +| `parts` | `boolean` | `false` | When `true`, the returned object will include an array of strings representing each path "segment" in the scanned glob pattern. This is automatically enabled when `options.tokens` is true | + +**Example** + +```js +const picomatch = require('picomatch'); +const result = picomatch.scan('!./foo/*.js', { tokens: true }); +console.log(result); +// { +// prefix: '!./', +// input: '!./foo/*.js', +// start: 3, +// base: 'foo', +// glob: '*.js', +// isBrace: false, +// isBracket: false, +// isGlob: true, +// isExtglob: false, +// isGlobstar: false, +// negated: true, +// maxDepth: 2, +// tokens: [ +// { value: '!./', depth: 0, isGlob: false, negated: true, isPrefix: true }, +// { value: 'foo', depth: 1, isGlob: false }, +// { value: '*.js', depth: 1, isGlob: true } +// ], +// slashes: [ 2, 6 ], +// parts: [ 'foo', '*.js' ] +// } +``` + +
+ +### Options Examples + +#### options.expandRange + +**Type**: `function` + +**Default**: `undefined` + +Custom function for expanding ranges in brace patterns. The [fill-range](https://github.com/jonschlinkert/fill-range) library is ideal for this purpose, or you can use custom code to do whatever you need. + +**Example** + +The following example shows how to create a glob that matches a folder + +```js +const fill = require('fill-range'); +const regex = pm.makeRe('foo/{01..25}/bar', { + expandRange(a, b) { + return `(${fill(a, b, { toRegex: true })})`; + } +}); + +console.log(regex); +//=> /^(?:foo\/((?:0[1-9]|1[0-9]|2[0-5]))\/bar)$/ + +console.log(regex.test('foo/00/bar')) // false +console.log(regex.test('foo/01/bar')) // true +console.log(regex.test('foo/10/bar')) // true +console.log(regex.test('foo/22/bar')) // true +console.log(regex.test('foo/25/bar')) // true +console.log(regex.test('foo/26/bar')) // false +``` + +#### options.format + +**Type**: `function` + +**Default**: `undefined` + +Custom function for formatting strings before they're matched. + +**Example** + +```js +// strip leading './' from strings +const format = str => str.replace(/^\.\//, ''); +const isMatch = picomatch('foo/*.js', { format }); +console.log(isMatch('./foo/bar.js')); //=> true +``` + +#### options.onMatch + +```js +const onMatch = ({ glob, regex, input, output }) => { + console.log({ glob, regex, input, output }); +}; + +const isMatch = picomatch('*', { onMatch }); +isMatch('foo'); +isMatch('bar'); +isMatch('baz'); +``` + +#### options.onIgnore + +```js +const onIgnore = ({ glob, regex, input, output }) => { + console.log({ glob, regex, input, output }); +}; + +const isMatch = picomatch('*', { onIgnore, ignore: 'f*' }); +isMatch('foo'); +isMatch('bar'); +isMatch('baz'); +``` + +#### options.onResult + +```js +const onResult = ({ glob, regex, input, output }) => { + console.log({ glob, regex, input, output }); +}; + +const isMatch = picomatch('*', { onResult, ignore: 'f*' }); +isMatch('foo'); +isMatch('bar'); +isMatch('baz'); +``` + +
+
+ +## Globbing features + +* [Basic globbing](#basic-globbing) (Wildcard matching) +* [Advanced globbing](#advanced-globbing) (extglobs, posix brackets, brace matching) + +### Basic globbing + +| **Character** | **Description** | +| --- | --- | +| `*` | Matches any character zero or more times, excluding path separators. Does _not match_ path separators or hidden files or directories ("dotfiles"), unless explicitly enabled by setting the `dot` option to `true`. | +| `**` | Matches any character zero or more times, including path separators. Note that `**` will only match path separators (`/`, and `\\` on Windows) when they are the only characters in a path segment. Thus, `foo**/bar` is equivalent to `foo*/bar`, and `foo/a**b/bar` is equivalent to `foo/a*b/bar`, and _more than two_ consecutive stars in a glob path segment are regarded as _a single star_. Thus, `foo/***/bar` is equivalent to `foo/*/bar`. | +| `?` | Matches any character excluding path separators one time. Does _not match_ path separators or leading dots. | +| `[abc]` | Matches any characters inside the brackets. For example, `[abc]` would match the characters `a`, `b` or `c`, and nothing else. | + +#### Matching behavior vs. Bash + +Picomatch's matching features and expected results in unit tests are based on Bash's unit tests and the Bash 4.3 specification, with the following exceptions: + +* Bash will match `foo/bar/baz` with `*`. Picomatch only matches nested directories with `**`. +* Bash greedily matches with negated extglobs. For example, Bash 4.3 says that `!(foo)*` should match `foo` and `foobar`, since the trailing `*` bracktracks to match the preceding pattern. This is very memory-inefficient, and IMHO, also incorrect. Picomatch would return `false` for both `foo` and `foobar`. + +
+ +### Advanced globbing + +* [extglobs](#extglobs) +* [POSIX brackets](#posix-brackets) +* [Braces](#brace-expansion) + +#### Extglobs + +| **Pattern** | **Description** | +| --- | --- | +| `@(pattern)` | Match _only one_ consecutive occurrence of `pattern` | +| `*(pattern)` | Match _zero or more_ consecutive occurrences of `pattern` | +| `+(pattern)` | Match _one or more_ consecutive occurrences of `pattern` | +| `?(pattern)` | Match _zero or **one**_ consecutive occurrences of `pattern` | +| `!(pattern)` | Match _anything but_ `pattern` | + +**Examples** + +```js +const pm = require('picomatch'); + +// *(pattern) matches ZERO or more of "pattern" +console.log(pm.isMatch('a', 'a*(z)')); // true +console.log(pm.isMatch('az', 'a*(z)')); // true +console.log(pm.isMatch('azzz', 'a*(z)')); // true + +// +(pattern) matches ONE or more of "pattern" +console.log(pm.isMatch('a', 'a*(z)')); // true +console.log(pm.isMatch('az', 'a*(z)')); // true +console.log(pm.isMatch('azzz', 'a*(z)')); // true + +// supports multiple extglobs +console.log(pm.isMatch('foo.bar', '!(foo).!(bar)')); // false + +// supports nested extglobs +console.log(pm.isMatch('foo.bar', '!(!(foo)).!(!(bar))')); // true +``` + +#### POSIX brackets + +POSIX classes are disabled by default. Enable this feature by setting the `posix` option to true. + +**Enable POSIX bracket support** + +```js +console.log(pm.makeRe('[[:word:]]+', { posix: true })); +//=> /^(?:(?=.)[A-Za-z0-9_]+\/?)$/ +``` + +**Supported POSIX classes** + +The following named POSIX bracket expressions are supported: + +* `[:alnum:]` - Alphanumeric characters, equ `[a-zA-Z0-9]` +* `[:alpha:]` - Alphabetical characters, equivalent to `[a-zA-Z]`. +* `[:ascii:]` - ASCII characters, equivalent to `[\\x00-\\x7F]`. +* `[:blank:]` - Space and tab characters, equivalent to `[ \\t]`. +* `[:cntrl:]` - Control characters, equivalent to `[\\x00-\\x1F\\x7F]`. +* `[:digit:]` - Numerical digits, equivalent to `[0-9]`. +* `[:graph:]` - Graph characters, equivalent to `[\\x21-\\x7E]`. +* `[:lower:]` - Lowercase letters, equivalent to `[a-z]`. +* `[:print:]` - Print characters, equivalent to `[\\x20-\\x7E ]`. +* `[:punct:]` - Punctuation and symbols, equivalent to `[\\-!"#$%&\'()\\*+,./:;<=>?@[\\]^_`{|}~]`. +* `[:space:]` - Extended space characters, equivalent to `[ \\t\\r\\n\\v\\f]`. +* `[:upper:]` - Uppercase letters, equivalent to `[A-Z]`. +* `[:word:]` - Word characters (letters, numbers and underscores), equivalent to `[A-Za-z0-9_]`. +* `[:xdigit:]` - Hexadecimal digits, equivalent to `[A-Fa-f0-9]`. + +See the [Bash Reference Manual](https://www.gnu.org/software/bash/manual/html_node/Pattern-Matching.html) for more information. + +### Braces + +Picomatch does not do brace expansion. For [brace expansion](https://www.gnu.org/software/bash/manual/html_node/Brace-Expansion.html) and advanced matching with braces, use [micromatch](https://github.com/micromatch/micromatch) instead. Picomatch has very basic support for braces. + +### Matching special characters as literals + +If you wish to match the following special characters in a filepath, and you want to use these characters in your glob pattern, they must be escaped with backslashes or quotes: + +**Special Characters** + +Some characters that are used for matching in regular expressions are also regarded as valid file path characters on some platforms. + +To match any of the following characters as literals: `$^*+?()[] + +Examples: + +```js +console.log(pm.makeRe('foo/bar \\(1\\)')); +console.log(pm.makeRe('foo/bar \\(1\\)')); +``` + +

+ +## Philosophies + +The goal of this library is to be blazing fast, without compromising on accuracy. + +**Accuracy** + +The number one of goal of this library is accuracy. However, it's not unusual for different glob implementations to have different rules for matching behavior, even with simple wildcard matching. It gets increasingly more complicated when combinations of different features are combined, like when extglobs are combined with globstars, braces, slashes, and so on: `!(**/{a,b,*/c})`. + +Thus, given that there is no canonical glob specification to use as a single source of truth when differences of opinion arise regarding behavior, sometimes we have to implement our best judgement and rely on feedback from users to make improvements. + +**Performance** + +Although this library performs well in benchmarks, and in most cases it's faster than other popular libraries we benchmarked against, we will always choose accuracy over performance. It's not helpful to anyone if our library is faster at returning the wrong answer. + +

This means that you do +not have to specify both `::ffff:a00:1` and `10.0.0.1`. + +As a convenience, this module also takes certain pre-defined names +in addition to IP addresses, which expand into IP addresses: + +```js +proxyaddr(req, 'loopback') +proxyaddr(req, ['loopback', 'fc00:ac:1ab5:fff::1/64']) +``` + + * `loopback`: IPv4 and IPv6 loopback addresses (like `::1` and + `127.0.0.1`). + * `linklocal`: IPv4 and IPv6 link-local addresses (like + `fe80::1:1:1:1` and `169.254.0.1`). + * `uniquelocal`: IPv4 private addresses and IPv6 unique-local + addresses (like `fc00:ac:1ab5:fff::1` and `192.168.0.1`). + +When `trust` is specified as a function, it will be called for each +address to determine if it is a trusted address. The function is +given two arguments: `addr` and `i`, where `addr` is a string of +the address to check and `i` is a number that represents the distance +from the socket address. + +### proxyaddr.all(req, [trust]) + +Return all the addresses of the request, optionally stopping at the +first untrusted. This array is ordered from closest to furthest +(i.e. `arr[0] === req.connection.remoteAddress`). + +```js +proxyaddr.all(req) +``` + +The optional `trust` argument takes the same arguments as `trust` +does in `proxyaddr(req, trust)`. + +```js +proxyaddr.all(req, 'loopback') +``` + +### proxyaddr.compile(val) + +Compiles argument `val` into a `trust` function. This function takes +the same arguments as `trust` does in `proxyaddr(req, trust)` and +returns a function suitable for `proxyaddr(req, trust)`. + +```js +var trust = proxyaddr.compile('loopback') +var addr = proxyaddr(req, trust) +``` + +This function is meant to be optimized for use against every request. +It is recommend to compile a trust function up-front for the trusted +configuration and pass that to `proxyaddr(req, trust)` for each request. + +## Testing + +```sh +$ npm test +``` + +## Benchmarks + +```sh +$ npm run-script bench +``` + +## License + +[MIT](LICENSE) + +[ci-image]: https://badgen.net/github/checks/jshttp/proxy-addr/master?label=ci +[ci-url]: https://github.com/jshttp/proxy-addr/actions?query=workflow%3Aci +[coveralls-image]: https://badgen.net/coveralls/c/github/jshttp/proxy-addr/master +[coveralls-url]: https://coveralls.io/r/jshttp/proxy-addr?branch=master +[node-image]: https://badgen.net/npm/node/proxy-addr +[node-url]: https://nodejs.org/en/download +[npm-downloads-image]: https://badgen.net/npm/dm/proxy-addr +[npm-url]: https://npmjs.org/package/proxy-addr +[npm-version-image]: https://badgen.net/npm/v/proxy-addr diff --git a/Week_4/node_modules/proxy-addr/index.js b/Week_4/node_modules/proxy-addr/index.js new file mode 100644 index 0000000..a909b05 --- /dev/null +++ b/Week_4/node_modules/proxy-addr/index.js @@ -0,0 +1,327 @@ +/*! + * proxy-addr + * Copyright(c) 2014-2016 Douglas Christopher Wilson + * MIT Licensed + */ + +'use strict' + +/** + * Module exports. + * @public + */ + +module.exports = proxyaddr +module.exports.all = alladdrs +module.exports.compile = compile + +/** + * Module dependencies. + * @private + */ + +var forwarded = require('forwarded') +var ipaddr = require('ipaddr.js') + +/** + * Variables. + * @private + */ + +var DIGIT_REGEXP = /^[0-9]+$/ +var isip = ipaddr.isValid +var parseip = ipaddr.parse + +/** + * Pre-defined IP ranges. + * @private + */ + +var IP_RANGES = { + linklocal: ['169.254.0.0/16', 'fe80::/10'], + loopback: ['127.0.0.1/8', '::1/128'], + uniquelocal: ['10.0.0.0/8', '172.16.0.0/12', '192.168.0.0/16', 'fc00::/7'] +} + +/** + * Get all addresses in the request, optionally stopping + * at the first untrusted. + * + * @param {Object} request + * @param {Function|Array|String} [trust] + * @public + */ + +function alladdrs (req, trust) { + // get addresses + var addrs = forwarded(req) + + if (!trust) { + // Return all addresses + return addrs + } + + if (typeof trust !== 'function') { + trust = compile(trust) + } + + for (var i = 0; i < addrs.length - 1; i++) { + if (trust(addrs[i], i)) continue + + addrs.length = i + 1 + } + + return addrs +} + +/** + * Compile argument into trust function. + * + * @param {Array|String} val + * @private + */ + +function compile (val) { + if (!val) { + throw new TypeError('argument is required') + } + + var trust + + if (typeof val === 'string') { + trust = [val] + } else if (Array.isArray(val)) { + trust = val.slice() + } else { + throw new TypeError('unsupported trust argument') + } + + for (var i = 0; i < trust.length; i++) { + val = trust[i] + + if (!Object.prototype.hasOwnProperty.call(IP_RANGES, val)) { + continue + } + + // Splice in pre-defined range + val = IP_RANGES[val] + trust.splice.apply(trust, [i, 1].concat(val)) + i += val.length - 1 + } + + return compileTrust(compileRangeSubnets(trust)) +} + +/** + * Compile `arr` elements into range subnets. + * + * @param {Array} arr + * @private + */ + +function compileRangeSubnets (arr) { + var rangeSubnets = new Array(arr.length) + + for (var i = 0; i < arr.length; i++) { + rangeSubnets[i] = parseipNotation(arr[i]) + } + + return rangeSubnets +} + +/** + * Compile range subnet array into trust function. + * + * @param {Array} rangeSubnets + * @private + */ + +function compileTrust (rangeSubnets) { + // Return optimized function based on length + var len = rangeSubnets.length + return len === 0 + ?

The strictDepth option adds a layer of protection by throwing an error when the limit is exceeded, allowing you to catch and handle such cases. + +For similar reasons, by default **qs** will only parse up to 1000 parameters. This can be overridden by passing a `parameterLimit` option: + +```javascript +var limited = qs.parse('a=b&c=d', { parameterLimit: 1 }); +assert.deepEqual(limited, { a: 'b' }); +``` + +To bypass the leading question mark, use `ignoreQueryPrefix`: + +```javascript +var prefixed = qs.parse('?a=b&c=d', { ignoreQueryPrefix: true }); +assert.deepEqual(prefixed, { a: 'b', c: 'd' }); +``` + +An optional delimiter can also be passed: + +```javascript +var delimited = qs.parse('a=b;c=d', { delimiter: ';' }); +assert.deepEqual(delimited, { a: 'b', c: 'd' }); +``` + +Delimiters can be a regular expression too: + +```javascript +var regexed = qs.parse('a=b;c=d,e=f', { delimiter: /[;,]/ }); +assert.deepEqual(regexed, { a: 'b', c: 'd', e: 'f' }); +``` + +Option `allowDots` can be used to enable dot notation: + +```javascript +var withDots = qs.parse('a.b=c', { allowDots: true }); +assert.deepEqual(withDots, { a: { b: 'c' } }); +``` + +Option `decodeDotInKeys` can be used to decode dots in keys +Note: it implies `allowDots`, so `parse` will error if you set `decodeDotInKeys` to `true`, and `allowDots` to `false`. + +```javascript +var withDots = qs.parse('name%252Eobj.first=John&name%252Eobj.last=Doe', { decodeDotInKeys: true }); +assert.deepEqual(withDots, { 'name.obj': { first: 'John', last: 'Doe' }}); +``` + +Option `allowEmptyArrays` can be used to allowing empty array values in object +```javascript +var withEmptyArrays = qs.parse('foo[]&bar=baz', { allowEmptyArrays: true }); +assert.deepEqual(withEmptyArrays, { foo: [], bar: 'baz' }); +``` + +Option `duplicates` can be used to change the behavior when duplicate keys are encountered +```javascript +assert.deepEqual(qs.parse('foo=bar&foo=baz'), { foo: ['bar', 'baz'] }); +assert.deepEqual(qs.parse('foo=bar&foo=baz', { duplicates: 'combine' }), { foo: ['bar', 'baz'] }); +assert.deepEqual(qs.parse('foo=bar&foo=baz', { duplicates: 'first' }), { foo: 'bar' }); +assert.deepEqual(qs.parse('foo=bar&foo=baz', { duplicates: 'last' }), { foo: 'baz' }); +``` + +If you have to deal with legacy browsers or services, there's also support for decoding percent-encoded octets as iso-8859-1: + +```javascript +var oldCharset = qs.parse('a=%A7', { charset: 'iso-8859-1' }); +assert.deepEqual(oldCharset, { a: '§' }); +``` + +Some services add an initial `utf8=✓` value to forms so that old Internet Explorer versions are more likely to submit the form as utf-8. +Additionally, the server can check the value against wrong encodings of the checkmark character and detect that a query string or `application/x-www-form-urlencoded` body was *not* sent as utf-8, eg. if the form had an `accept-charset` parameter or the containing page had a different character set. + +**qs** supports this mechanism via the `charsetSentinel` option. +If specified, the `utf8` parameter will be omitted from the returned object. +It will be used to switch to `iso-8859-1`/`utf-8` mode depending on how the checkmark is encoded. + +**Important**: When you specify both the `charset` option and the `charsetSentinel` option, the `charset` will be overridden when the request contains a `utf8` parameter from which the actual charset can be deduced. +In that sense the `charset` will behave as the default charset rather than the authoritative charset. + +```javascript +var detectedAsUtf8 = qs.parse('utf8=%E2%9C%93&a=%C3%B8', { + charset: 'iso-8859-1', + charsetSentinel: true +}); +assert.deepEqual(detectedAsUtf8, { a: 'ø' }); + +// Browsers encode the checkmark as ✓ when submitting as iso-8859-1: +var detectedAsIso8859_1 = qs.parse('utf8=%26%2310003%3B&a=%F8', { + charset: 'utf-8', + charsetSentinel: true +}); +assert.deepEqual(detectedAsIso8859_1, { a: 'ø' }); +``` + +If you want to decode the `&#...;` syntax to the actual character, you can specify the `interpretNumericEntities` option as well: + +```javascript +var detectedAsIso8859_1 = qs.parse('a=%26%239786%3B', { + charset: 'iso-8859-1', + interpretNumericEntities: true +}); +assert.deepEqual(detectedAsIso8859_1, { a: '☺' }); +``` + +It also works when the charset has been detected in `charsetSentinel` mode. + +### Parsing Arrays + +**qs** can also parse arrays using a similar `[]` notation: + +```javascript +var withArray = qs.parse('a[]=b&a[]=c'); +assert.deepEqual(withArray, { a: ['b', 'c'] }); +``` + +You may specify an index as well: + +```javascript +var withIndexes = qs.parse('a[1]=c&a[0]=b'); +assert.deepEqual(withIndexes, { a: ['b', 'c'] }); +``` + +Note that the only difference between an index in an array and a key in an object is that the value between the brackets must be a number to create an array. +When creating arrays with specific indices, **qs** will compact a sparse array to only the existing values preserving their order: + +```javascript +var noSparse = qs.parse('a[1]=b&a[15]=c'); +assert.deepEqual(noSparse, { a: ['b', 'c'] }); +``` + +You may also use `allowSparse` option to parse sparse arrays: + +```javascript +var sparseArray = qs.parse('a[1]=2&a[3]=5', { allowSparse: true }); +assert.deepEqual(sparseArray, { a: [, '2', , '5'] }); +``` + +Note that an empty string is also a value, and will be preserved: + +```javascript +var withEmptyString = qs.parse('a[]=&a[]=b'); +assert.deepEqual(withEmptyString, { a: ['', 'b'] }); + +var withIndexedEmptyString = qs.parse('a[0]=b&a[1]=&a[2]=c'); +assert.deepEqual(withIndexedEmptyString, { a: ['b', '', 'c'] }); +``` + +**qs** will also limit specifying indices in an array to a maximum index of `20`. +Any array members with an index of greater than `20` will instead be converted to an object with the index as the key. +This is needed to handle cases when someone sent, for example, `a[999999999]` and it will take significant time to iterate over this huge array. + +```javascript +var withMaxIndex = qs.parse('a[100]=b'); +assert.deepEqual(withMaxIndex, { a: { '100': 'b' } }); +``` + +This limit can be overridden by passing an `arrayLimit` option: + +```javascript +var withArrayLimit = qs.parse('a[1]=b', { arrayLimit: 0 }); +assert.deepEqual(withArrayLimit, { a: { '1': 'b' } }); +``` + +To disable array parsing entirely, set `parseArrays` to `false`. + +```javascript +var noParsingArrays = qs.parse('a[]=b', { parseArrays: false }); +assert.deepEqual(noParsingArrays, { a: { '0': 'b' } }); +``` + +If you mix notations, **qs** will merge the two items into an object: + +```javascript +var mixedNotation = qs.parse('a[0]=b&a[b]=c'); +assert.deepEqual(mixedNotation, { a: { '0': 'b', b: 'c' } }); +``` + +You can also create arrays of objects: + +```javascript +var arraysOfObjects = qs.parse('a[][b]=c'); +assert.deepEqual(arraysOfObjects, { a: [{ b: 'c' }] }); +``` + +Some people use comma to join array, **qs** can parse it: +```javascript +var arraysOfObjects = qs.parse('a=b,c', { comma: true }) +assert.deepEqual(arraysOfObjects, { a: ['b', 'c'] }) +``` +(_this cannot convert nested objects, such as `a={b:1},{c:d}`_) + +### Parsing primitive/scalar values (numbers, booleans, null, etc) + +By default, all values are parsed as strings. +This behavior will not change and is explained in [issue #91](https://github.com/ljharb/qs/issues/91). + +```javascript +var primitiveValues = qs.parse('a=15&b=true&c=null'); +assert.deepEqual(primitiveValues, { a: '15', b: 'true', c: 'null' }); +``` + +If you wish to auto-convert values which look like numbers, booleans, and other values into their primitive counterparts, you can use the [query-types Express JS middleware](https://github.com/xpepermint/query-types) which will auto-convert all request query parameters. + +### Stringifying + +[](#preventEval) +```javascript +qs.stringify(object, [options]); +``` + +When stringifying, **qs** by default URI encodes output. Objects are stringified as you would expect: + +```javascript +assert.equal(qs.stringify({ a: 'b' }), 'a=b'); +assert.equal(qs.stringify({ a: { b: 'c' } }), 'a%5Bb%5D=c'); +``` + +This encoding can be disabled by setting the `encode` option to `false`: + +```javascript +var unencoded = qs.stringify({ a: { b: 'c' } }, { encode: false }); +assert.equal(unencoded, 'a[b]=c'); +``` + +Encoding can be disabled for keys by setting the `encodeValuesOnly` option to `true`: +```javascript +var encodedValues = qs.stringify( + { a: 'b', c: ['d', 'e=f'], f: [['g'], ['h']] }, + { encodeValuesOnly: true } +); +assert.equal(encodedValues,'a=b&c[0]=d&c[1]=e%3Df&f[0][0]=g&f[1][0]=h'); +``` + +This encoding can also be replaced by a custom encoding method set as `encoder` option: + +```javascript +var encoded = qs.stringify({ a: { b: 'c' } }, { encoder: function (str) { + // Passed in values `a`, `b`, `c` + return // Return encoded string +}}) +``` + +_(Note: the `encoder` option does not apply if `encode` is `false`)_ + +Analogue to the `encoder` there is a `decoder` option for `parse` to override decoding of properties and values: + +```javascript +var decoded = qs.parse('x=z', { decoder: function (str) { + // Passed in values `x`, `z` + return // Return decoded string +}}) +``` + +You can encode keys and values using different logic by using the type argument provided to the encoder: + +```javascript +var encoded = qs.stringify({ a: { b: 'c' } }, { encoder: function (str, defaultEncoder, charset, type) { + if (type === 'key') { + return // Encoded key + } else if (type === 'value') { + return // Encoded value + } +}}) +``` + +The type argument is also provided to the decoder: + +```javascript +var decoded = qs.parse('x=z', { decoder: function (str, defaultDecoder, charset, type) { + if (type === 'key') { + return // Decoded key + } else if (type === 'value') { + return // Decoded value + } +}}) +``` + +Examples beyond this point will be shown as though the output is not URI encoded for clarity. +Please note that the return values in these cases *will* be URI encoded during real usage. + +When arrays are stringified, they follow the `arrayFormat` option, which defaults to `indices`: + +```javascript +qs.stringify({ a: ['b', 'c', 'd'] }); +// 'a[0]=b&a[1]=c&a[2]=d' +``` + +You may override this by setting the `indices` option to `false`, or to be more explicit, the `arrayFormat` option to `repeat`: + +```javascript +qs.stringify({ a: ['b', 'c', 'd'] }, { indices: false }); +// 'a=b&a=c&a=d' +``` + +You may use the `arrayFormat` option to specify the format of the output array: + +```javascript +qs.stringify({ a: ['b', 'c'] }, { arrayFormat: 'indices' }) +// 'a[0]=b&a[1]=c' +qs.stringify({ a: ['b', 'c'] }, { arrayFormat: 'brackets' }) +// 'a[]=b&a[]=c' +qs.stringify({ a: ['b', 'c'] }, { arrayFormat: 'repeat' }) +// 'a=b&a=c' +qs.stringify({ a: ['b', 'c'] }, { arrayFormat: 'comma' }) +// 'a=b,c' +``` + +Note: when using `arrayFormat` set to `'comma'`, you can also pass the `commaRoundTrip` option set to `true` or `false`, to append `[]` on single-item arrays, so that they can round trip through a parse. + +When objects are stringified, by default they use bracket notation: + +```javascript +qs.stringify({ a: { b: { c: 'd', e: 'f' } } }); +// 'a[b][c]=d&a[b][e]=f' +``` + +You may override this to use dot notation by setting the `allowDots` option to `true`: + +```javascript +qs.stringify({ a: { b: { c: 'd', e: 'f' } } }, { allowDots: true }); +// 'a.b.c=d&a.b.e=f' +``` + +You may encode the dot notation in the keys of object with option `encodeDotInKeys` by setting it to `true`: +Note: it implies `allowDots`, so `stringify` will error if you set `decodeDotInKeys` to `true`, and `allowDots` to `false`. +Caveat: when `encodeValuesOnly` is `true` as well as `encodeDotInKeys`, only dots in keys and nothing else will be encoded. +```javascript +qs.stringify({ "name.obj": { "first": "John", "last": "Doe" } }, { allowDots: true, encodeDotInKeys: true }) +// 'name%252Eobj.first=John&name%252Eobj.last=Doe' +``` + +You may allow empty array values by setting the `allowEmptyArrays` option to `true`: +```javascript +qs.stringify({ foo: [], bar: 'baz' }, { allowEmptyArrays: true }); +// 'foo[]&bar=baz' +``` + +Empty strings and null values will omit the value, but the equals sign (=) remains in place: + +```javascript +assert.equal(qs.stringify({ a: '' }), 'a='); +``` + +Key with no values (such as an empty object or array) will return nothing: + +```javascript +assert.equal(qs.stringify({ a: [] }), ''); +assert.equal(qs.stringify({ a: {} }), ''); +assert.equal(qs.stringify({ a: [{}] }), ''); +assert.equal(qs.stringify({ a: { b: []} }), ''); +assert.equal(qs.stringify({ a: { b: {}} }), ''); +``` + +Properties that are set to `undefined` will be omitted entirely: + +```javascript +assert.equal(qs.stringify({ a: null, b: undefined }), 'a='); +``` + +The query string may optionally be prepended with a question mark: + +```javascript +assert.equal(qs.stringify({ a: 'b', c: 'd' }, { addQueryPrefix: true }), '?a=b&c=d'); +``` + +The delimiter may be overridden with stringify as well: + +```javascript +assert.equal(qs.stringify({ a: 'b', c: 'd' }, { delimiter: ';' }), 'a=b;c=d'); +``` + +If you only want to override the serialization of `Date` objects, you can provide a `serializeDate` option: + +```javascript +var date = new Date(7); +assert.equal(qs.stringify({ a: date }), 'a=1970-01-01T00:00:00.007Z'.replace(/:/g, '%3A')); +assert.equal( + qs.stringify({ a: date }, { serializeDate: function (d) { return d.getTime(); } }), + 'a=7' +); +``` + +You may use the `sort` option to affect the order of parameter keys: + +```javascript +function alphabeticalSort(a, b) { + return a.localeCompare(b); +} +assert.equal(qs.stringify({ a: 'c', z: 'y', b : 'f' }, { sort: alphabeticalSort }), 'a=c&b=f&z=y'); +``` + +Finally, you can use the `filter` option to restrict which keys will be included in the stringified output. +If you pass a function, it will be called for each key to obtain the replacement value. +Otherwise, if you pass an array, it will be used to select properties and array indices for stringification: + +```javascript +function filterFunc(prefix, value) { + if (prefix == 'b') { + // Return an `undefined` value to omit a property. + return; + } + if (prefix == 'e[f]') { + return value.getTime(); + } + if (prefix == 'e[g][0]') { + return value * 2; + } + return value; +} +qs.stringify({ a: 'b', c: 'd', e: { f: new Date(123), g: [2] } }, { filter: filterFunc }); +// 'a=b&c=d&e[f]=123&e[g][0]=4' +qs.stringify({ a: 'b', c: 'd', e: 'f' }, { filter: ['a', 'e'] }); +// 'a=b&e=f' +qs.stringify({ a: ['b', 'c', 'd'], e: 'f' }, { filter: ['a', 0, 2] }); +// 'a[0]=b&a[2]=d' +``` + +You could also use `filter` to inject custom serialization for user defined types. +Consider you're working with some api that expects query strings of the format for ranges: + +``` +https://domain.com/endpoint?range=30...70 +``` + +For which you model as: + +```javascript +class Range { + constructor(from, to) { + this.from = from; + this.to = to; + } +} +``` + +You could _inject_ a custom serializer to handle values of this type: + +```javascript +qs.stringify( + { + range: new Range(30, 70), + }, + { + filter: (prefix, value) => { + if (value instanceof Range) { + return `${value.from}...${value.to}`; + } + // serialize the usual way + return value; + }, + } +); +// range=30...70 +``` + +### Handling of `null` values + +By default, `null` values are treated like empty strings: + +```javascript +var withNull = qs.stringify({ a: null, b: '' }); +assert.equal(withNull, 'a=&b='); +``` + +Parsing does not distinguish between parameters with and without equal signs. +Both are converted to empty strings. + +```javascript +var equalsInsensitive = qs.parse('a&b='); +assert.deepEqual(equalsInsensitive, { a: '', b: '' }); +``` + +To distinguish between `null` values and empty strings use the `strictNullHandling` flag. In the result string the `null` +values have no `=` sign: + +```javascript +var strictNull = qs.stringify({ a: null, b: '' }, { strictNullHandling: true }); +assert.equal(strictNull, 'a&b='); +``` + +To parse values without `=` back to `null` use the `strictNullHandling` flag: + +```javascript +var parsedStrictNull = qs.parse('a&b=', { strictNullHandling: true }); +assert.deepEqual(parsedStrictNull, { a: null, b: '' }); +``` + +To completely skip rendering keys with `null` values, use the `skipNulls` flag: + +```javascript +var nullsSkipped = qs.stringify({ a: 'b', c: null}, { skipNulls: true }); +assert.equal(nullsSkipped, 'a=b'); +``` + +If you're communicating with legacy systems, you can switch to `iso-8859-1` using the `charset` option: + +```javascript +var iso = qs.stringify({ æ: 'æ' }, { charset: 'iso-8859-1' }); +assert.equal(iso, '%E6=%E6'); +``` + +Characters that don't exist in `iso-8859-1` will be converted to numeric entities, similar to what browsers do: + +```javascript +var numeric = qs.stringify({ a: '☺' }, { charset: 'iso-8859-1' }); +assert.equal(numeric, 'a=%26%239786%3B'); +``` + +You can use the `charsetSentinel` option to announce the character by including an `utf8=✓` parameter with the proper encoding if the checkmark, similar to what Ruby on Rails and others do when submitting forms. + +```javascript +var sentinel = qs.stringify({ a: '☺' }, { charsetSentinel: true }); +assert.equal(sentinel, 'utf8=%E2%9C%93&a=%E2%98%BA'); + +var isoSentinel = qs.stringify({ a: 'æ' }, { charsetSentinel: true, charset: 'iso-8859-1' }); +assert.equal(isoSentinel, 'utf8=%26%2310003%3B&a=%E6'); +``` + +### Dealing with special character sets + +By default the encoding and decoding of characters is done in `utf-8`, and `iso-8859-1` support is also built in via the `charset` parameter. + +If you wish to encode querystrings to a different character set (i.e. +[Shift JIS](https://en.wikipedia.org/wiki/Shift_JIS)) you can use the +[`qs-iconv`](https://github.com/martinheidegger/qs-iconv) library: + +```javascript +var encoder = require('qs-iconv/encoder')('shift_jis'); +var shiftJISEncoded = qs.stringify({ a: 'こんにちは！' }, { encoder: encoder }); +assert.equal(shiftJISEncoded, 'a=%82%B1%82%F1%82%C9%82%BF%82%CD%81I'); +``` + +This also works for decoding of query strings: + +```javascript +var decoder = require('qs-iconv/decoder')('shift_jis'); +var obj = qs.parse('a=%82%B1%82%F1%82%C9%82%BF%82%CD%81I', { decoder: decoder }); +assert.deepEqual(obj, { a: 'こんにちは！' }); +``` + +### RFC 3986 and RFC 1738 space encoding + +RFC3986 used as default option and encodes ' ' to *%20* which is backward compatible. +In the same time, output can be stringified as per RFC1738 with ' ' equal to '+'. + +``` +assert.equal(qs.stringify({ a: 'b c' }), 'a=b%20c'); +assert.equal(qs.stringify({ a: 'b c' }, { format : 'RFC3986' }), 'a=b%20c'); +assert.equal(qs.stringify({ a: 'b c' }, { format : 'RFC1738' }), 'a=b+c'); +``` + +## Security + +Please email [@ljharb](https://github.com/ljharb) or see https://tidelift.com/security if you have a potential security vulnerability to report. + +## qs for

Example: inaccessible to the user. +- `on('error', (error) => {})` fatal `Error` which also ends the stream. Example: illegal options where passed. +- `on('end')` — we are done. Called when all entries were found and no more will be emitted. +- `on('close')` — stream is destroyed via `stream.destroy()`. + Could be useful if you want to manually abort even on a non fatal error. + At that point the stream is no longer `readable` and no more entries, warning or errors are emitted +- To learn more about streams, consult the very detailed [nodejs streams documentation](https://nodejs.org/api/stream.html) + or the [stream-handbook](https://github.com/substack/stream-handbook) + +`const entries = await readdirp.promise(root[, options])` — **Promise API**. Returns a list of [entry infos](#entryinfo). + +First argument is awalys `root`, path in which to start reading and recursing into subdirectories. + +### options + +- `fileFilter: ["*.js"]`: filter to include or exclude files. A `Function`, Glob string or Array of glob strings. + - **Function**: a function that takes an entry info as a parameter and returns true to include or false to exclude the entry + - **Glob string**: a string (e.g., `*.js`) which is matched using [picomatch](https://github.com/micromatch/picomatch), so go there for more + information. Globstars (`**`) are not supported since specifying a recursive pattern for an already recursive function doesn't make sense. Negated globs (as explained in the minimatch documentation) are allowed, e.g., `!*.txt` matches everything but text files. + - **Array of glob strings**: either need to be all inclusive or all exclusive (negated) patterns otherwise an error is thrown. + `['*.json', '*.js']` includes all JavaScript and Json files. + `['!.git', '!node_modules']` includes all directories except the '.git' and 'node_modules'. + - Directories that do not pass a filter will not be recursed into. +- `directoryFilter: ['!.git']`: filter to include/exclude directories found and to recurse into. Directories that do not pass a filter will not be recursed into. +- `depth: 5`: depth at which to stop recursing even if more subdirectories are found +- `type: 'files'`: determines if data events on the stream should be emitted for `'files'` (default), `'directories'`, `'files_directories'`, or `'all'`. Setting to `'all'` will also include entries for other types of file descriptors like character devices, unix sockets and named pipes. +- `alwaysStat: false`: always return `stats` property for every file. Default is `false`, readdirp will return `Dirent` entries. Setting it to `true` can double readdir execution time - use it only when you need file `size`, `mtime` etc. Cannot be enabled on node <10.10.0. +- `lstat: false`: include symlink entries in the stream along with files. When `true`, `fs.lstat` would be used instead of `fs.stat` + +### `EntryInfo` + +Has the following properties: + +- `path: 'assets/javascripts/react.js'`: path to the file/directory (relative to given root) +- `fullPath: '/Users/dev/projects/app/assets/javascripts/react.js'`: full path to the file/directory found +- `basename: 'react.js'`: name of the file/directory +- `dirent: fs.Dirent`: built-in [dir entry object](https://nodejs.org/api/fs.html#fs_class_fs_dirent) - only with `alwaysStat: false` +- `stats: fs.Stats`: built in [stat object](https://nodejs.org/api/fs.html#fs_class_fs_stats) - only with `alwaysStat: true` + +## Changelog + +- 3.5 (Oct 13, 2020) disallows recursive directory-based symlinks. + Before, it could have entered infinite loop. +- 3.4 (Mar 19, 2020) adds support for directory-based symlinks. +- 3.3 (Dec 6, 2019) stabilizes RAM consumption and enables perf management with `highWaterMark` option. Fixes race conditions related to `for-await` looping. +- 3.2 (Oct 14, 2019) improves performance by 250% and makes streams implementation more idiomatic. +- 3.1 (Jul 7, 2019) brings `bigint` support to `stat` output on Windows. This is backwards-incompatible for some cases. Be careful.

The contents of the newly created `Buffer` are unknown and +*may contain sensitive data*. Use [`buf.fill(0)`][] to initialize such +`Buffer` instances to zeroes. + +When using `Buffer.allocUnsafe()` to allocate new `Buffer` instances, +allocations under 4KB are, by default, sliced from a single pre-allocated +`Buffer`. This allows applications to avoid the garbage collection overhead of +creating many individually allocated Buffers. This approach improves both +performance and memory usage by eliminating the need to track and cleanup as +many `Persistent` objects. + +However, in the case where a developer may need to retain a small chunk of +memory from a pool for an indeterminate amount of time, it may be appropriate +to create an un-pooled Buffer instance using `Buffer.allocUnsafeSlow()` then +copy out the relevant bits. + +```js +// need to keep around a few small chunks of memory +const store = []; + +socket.on('readable', () => { + const data = socket.read(); + // allocate for retained data + const sb = Buffer.allocUnsafeSlow(10); + // copy the data into the new allocation + data.copy(sb, 0, 0, 10); + store.push(sb); +}); +``` + +Use of `Buffer.allocUnsafeSlow()` should be used only as a last resort *after* +a developer has observed undue memory retention in their applications. + +A `TypeError` will be thrown if `size` is not a number. + +### All the Rest + +The rest of the `Buffer` API is exactly the same as in node.js. +[See the docs](https://nodejs.org/api/buffer.html). + + +## Related links + +- [Node.js issue: Buffer(number) is unsafe](https://github.com/nodejs/node/issues/4660) +- [Node.js Enhancement Proposal: Buffer.from/Buffer.alloc/Buffer.zalloc/Buffer() soft-deprecate](https://github.com/nodejs/node-eps/pull/4) + +## Why is `Buffer` unsafe? + +Today, the node.js `Buffer` constructor is overloaded to handle many different argument +types like `String`, `Array`, `Object`, `TypedArrayView` (`Uint8Array`, etc.), +`ArrayBuffer`, and also `Number`. + +The API is optimized for convenience: you can throw any type at it, and it will try to do +what you want. + +Because the Buffer constructor is so powerful, you often see code like this: + +```js +// Convert UTF-8 strings to hex +function toHex (str) { + return new Buffer(str).toString('hex') +} +``` + +***But what happens if `toHex` is called with a `Number` argument?*** + +### Remote Memory Disclosure + +If an attacker can make your program call the `Buffer` constructor with a `Number` +argument, then they can make it allocate uninitialized memory from the node.js process. +This could potentially disclose TLS private keys, user data, or database passwords. + +When the `Buffer` constructor is passed a `Number` argument, it returns an +**UNINITIALIZED** block of memory of the specified `size`.

It's surprisingly common to forget to check the type of your variables in a +dynamically-typed language like JavaScript. + +Usually the consequences of assuming the wrong type is that your program crashes with an +uncaught exception. But the failure mode for forgetting to check the type of arguments to +the `Buffer` constructor is more catastrophic. + +Here's an example of a vulnerable service that takes a JSON payload and converts it to +hex: + +```js +// Take a JSON payload {str: "some string"} and convert it to hex +var server = http.createServer(function (req, res) { + var data = '' + req.setEncoding('utf8') + req.on('data', function (chunk) { + data += chunk + }) + req.on('end', function () { + var body = JSON.parse(data) + res.end(new Buffer(body.str).toString('hex')) + }) +}) + +server.listen(8080) +``` + +In this example, an http client just has to send: + +```json +{ + "str": 1000 +} +``` + +and it will get back 1,000 bytes of uninitialized memory from the server. + +This is a very serious bug. It's similar in severity to the +[the Heartbleed bug](http://heartbleed.com/) that allowed disclosure of OpenSSL process +memory by remote attackers. + + +### Which real-world packages were vulnerable? + +#### [`bittorrent-dht`](https://www.npmjs.com/package/bittorrent-dht) + +[Mathias Buus](https://github.com/mafintosh) and I +([Feross Aboukhadijeh](http://feross.org/)) found this issue in one of our own packages, +[`bittorrent-dht`](https://www.npmjs.com/package/bittorrent-dht). The bug would allow +anyone on the internet to send a series of messages to a user of `bittorrent-dht` and get +them to reveal 20 bytes at a time of uninitialized memory from the node.js process. + +Here's +[the commit](https://github.com/feross/bittorrent-dht/commit/6c7da04025d5633699800a99ec3fbadf70ad35b8) +that fixed it. We released a new fixed version, created a +[Node Security Project disclosure](https://nodesecurity.io/advisories/68), and deprecated all +vulnerable versions on npm so users will get a warning to upgrade to a newer version. + +#### [`ws`](https://www.npmjs.com/package/ws) + +That got us wondering if there were other vulnerable packages. Sure enough, within a short +period of time, we found the same issue in [`ws`](https://www.npmjs.com/package/ws), the +most popular WebSocket implementation in node.js. + +If certain APIs were called with `Number` parameters instead of `String` or `Buffer` as +expected, then uninitialized server memory would be disclosed to the remote peer. + +These were the vulnerable methods: + +```js +socket.send(number) +socket.ping(number) +socket.pong(number) +``` + +Here's a vulnerable socket server with some echo functionality: + +```js +server.on('connection', function (socket) { + socket.on('message', function (message) { + message = JSON.parse(message) + if (message.type === 'echo') { + socket.send(message.data) // send back the user's message + } + }) +}) +``` + +`socket.send(number)` called on the server, will disclose server memory. + +Here's [the release](https://github.com/websockets/ws/releases/tag/1.0.1) where the issue +was fixed, with a more detailed explanation. Props to +[Arnout Kazemier](https://github.com/3rd-Eden) for the quick fix. Here's the +[Node Security Project disclosure](https://nodesecurity.io/advisories/67). + + +### What's the solution? + +It's important that node.js offers a fast way to get memory otherwise performance-critical +applications would needlessly get a lot slower. + +But we need a better way to *signal our intent* as programmers. **When we want +uninitialized memory, we should request it explicitly.** + +Sensitive functionality should not be packed into a developer-friendly API that loosely +accepts many different types. This type of API encourages the lazy practice of passing +variables in without checking the type very carefully. + +#### A new API: `Buffer.allocUnsafe(number)` + +The functionality of creating buffers with uninitialized memory should be part of another +API. We propose `Buffer.allocUnsafe(number)`. This way, it's not part of an API that +frequently gets user input of all sorts of different types passed into it. + +```js +var buf = Buffer.allocUnsafe(16) // careful, uninitialized memory! + +// Immediately overwrite the uninitialized buffer with data from another buffer +for (var i = 0; i < buf.length; i++) { + buf[i] = otherBuf[i] +} +``` + + +### How do we fix node.js core? + +We sent [a PR to node.js core](https://github.com/nodejs/node/pull/4514) (merged as +`semver-major`) which defends against one case: + +```js +var str = 16 +new Buffer(str, 'utf8') +``` + +In this situation, it's implied that the programmer intended the first argument to be a +string, since they passed an encoding as a second argument. Today, node.js will allocate +uninitialized memory in the case of `new Buffer(number, encoding)`, which is probably not +what the programmer intended. + +But this is only a partial solution, since if the programmer does `new Buffer(variable)` +(without an `encoding` parameter) there's no way to know what they intended. If `variable` +is sometimes a number, then uninitialized memory will sometimes be returned. + +### What's the real long-term fix? + +We could deprecate and remove `new Buffer(number)` and use `Buffer.allocUnsafe(number)` when +we need uninitialized memory. But that would break 1000s of packages. + +~~We believe the best solution is to:~~ + +~~1. Change `new Buffer(number)` to return safe, zeroed-out memory~~ + +~~2. Create a new API for creating uninitialized Buffers. We propose: `Buffer.allocUnsafe(number)`~~ + +#### Update + +We now support adding three new APIs: + +- `Buffer.from(value)` - convert from any type to a buffer +- `Buffer.alloc(size)` - create a zero-filled buffer +- `Buffer.allocUnsafe(size)` - create an uninitialized buffer with given size + +This solves the core problem that affected `ws` and `bittorrent-dht` which is +`Buffer(variable)` getting tricked into taking a number argument. + +This way, existing code continues working and the impact on the npm ecosystem will be +minimal. Over time, npm maintainers can migrate performance-critical code to use +`Buffer.allocUnsafe(number)` instead of `new Buffer(number)`. + + +### Conclusion + +We think there's a serious design issue with the `Buffer` API as it exists today. It +promotes insecure software by putting high-risk functionality into a convenient API +with friendly "developer ergonomics". + +This wasn't merely a theoretical exercise because we found the issue in some of the +most popular npm packages. + +Fortunately, there's an easy fix that can be applied today. Use `safe-buffer` in place of +`buffer`. + +```js +var Buffer = require('safe-buffer').Buffer +``` + +Eventually, we hope that node.js core can switch to this new, safer behavior. We believe +the impact on the ecosystem would be minimal since it's not a breaking change. +Well-maintained, popular packages would be updated to use `Buffer.alloc` quickly, while +older, insecure packages would magically become safe from this attack vector. + + +## links + +- [Node.js PR: buffer: throw if both length and enc are passed](https://github.com/nodejs/node/pull/4514) +- [Node Security Project disclosure for `ws`](https://nodesecurity.io/advisories/67) +- [Node Security Project disclosure for`bittorrent-dht`](https://nodesecurity.io/advisories/68) + + +## credit + +The original issues in `bittorrent-dht` +([disclosure](https://nodesecurity.io/advisories/68)) and +`ws` ([disclosure](https://nodesecurity.io/advisories/67)) were discovered by +[Mathias Buus](https://github.com/mafintosh) and +[Feross Aboukhadijeh](http://feross.org/). + +Thanks to [Adam Baldwin](https://github.com/evilpacket) for helping disclose these issues +and for his work running the [Node Security Project](https://nodesecurity.io/). + +Thanks to [John Hiesey](https://github.com/jhiesey) for proofreading this README and +auditing the code. + + +## license + +MIT.

I have seen people doing that mistake. + +Enabling eslint rule [no-buffer-constructor](https://eslint.org/docs/rules/no-buffer-constructor) +or +[node/no-deprecated-api](https://github.com/mysticatea/eslint-plugin-node/blob/master/docs/rules/no-deprecated-api.md) +is recommended. + +_Don't forget to drop the polyfill usage once you drop support for Node.js < 4.5.0._ + + +## Variant 3 — manual detection, with safeguards + +This is useful if you create Buffer instances in only a few places (e.g. one), or you have your own +wrapper around them. + +### Buffer(0) + +This special case for creating empty buffers can be safely replaced with `Buffer.concat([])`, which +returns the same result all the way down to Node.js 0.8.x. + +### Buffer(notNumber) + +Before: + +```js +var buf = new Buffer(notNumber, encoding); +``` + +After: + +```js +var buf; +if (Buffer.from && Buffer.from !== Uint8Array.from) { + buf = Buffer.from(notNumber, encoding); +} else { + if (typeof notNumber === 'number') + throw new Error('The "size" argument must be of type number.'); + buf = new Buffer(notNumber, encoding); +} +``` + +`encoding` is optional. + +Note that the `typeof notNumber` before `new Buffer` is required (for cases when `notNumber` argument is not +hard-coded) and _is not caused by the deprecation of Buffer constructor_ — it's exactly _why_ the +Buffer constructor is deprecated. Ecosystem packages lacking this type-check caused numereous +security issues — situations when unsanitized user input could end up in the `Buffer(arg)` create +problems ranging from DoS to leaking sensitive information to the attacker from the process memory. + +When `notNumber` argument is hardcoded (e.g. literal `"abc"` or `[0,1,2]`), the `typeof` check can +be omitted. + +Also note that using TypeScript does not fix this problem for you — when libs written in +`TypeScript` are used from JS, or when user input ends up there — it behaves exactly as pure JS, as +all type checks are translation-time only and are not present in the actual JS code which TS +compiles to. + +### Buffer(number) + +For Node.js 0.10.x (and below) support: + +```js +var buf; +if (Buffer.alloc) { + buf = Buffer.alloc(number); +} else { + buf = new Buffer(number); + buf.fill(0); +} +``` + +Otherwise (Node.js ≥ 0.12.x): + +```js +const buf = Buffer.alloc ? Buffer.alloc(number) : new Buffer(number).fill(0); +``` + +## Regarding Buffer.allocUnsafe + +Be extra cautious when using `Buffer.allocUnsafe`: + * Don't use it if you don't have a good reason to + * e.g. you probably won't ever see a performance difference for small buffers, in fact, those + might be even faster with `Buffer.alloc()`, + * if your code is not in the hot code path — you also probably won't notice a difference, + * keep in mind that zero-filling minimizes the potential risks. + * If you use it, make sure that you never return the buffer in a partially-filled state, + * if you are writing to it sequentially — always truncate it to the actuall written length + +Errors in handling buffers allocated with `Buffer.allocUnsafe` could result in various issues, +ranged from undefined behaviour of your code to sensitive data (user input, passwords, certs) +leaking to the remote attacker. + +_Note that the same applies to `new Buffer` usage without zero-filling, depending on the Node.js +version (and lacking type checks also adds DoS to the list of potential problems)._ + + +## FAQ + + +### What is wrong with the `Buffer` constructor? + +The `Buffer` constructor could be used to create a buffer in many different ways: + +- `new Buffer(42)` creates a `Buffer` of 42 bytes. Before Node.js 8, this buffer contained + *arbitrary memory* for performance reasons, which could include anything ranging from + program source code to passwords and encryption keys. +- `new Buffer('abc')` creates a `Buffer` that contains the UTF-8-encoded version of + the string `'abc'`. A second argument could specify another encoding: For example, + `new Buffer(string, 'base64')` could be used to convert a Base64 string into the original + sequence of bytes that it represents. +- There are several other combinations of arguments. + +This meant that, in code like `var buffer = new Buffer(foo);`, *it is not possible to tell +what exactly the contents of the generated buffer are* without knowing the type of `foo`. + +Sometimes, the value of `foo` comes from an external source. For example, this function +could be exposed as a service on a web server, converting a UTF-8 string into its Base64 form: + +``` +function stringToBase64(req, res) { + // The request body should have the format of `{ string: 'foobar' }` + const rawBytes = new Buffer(req.body.string) + const encoded = rawBytes.toString('base64') + res.end({ encoded: encoded }) +} +``` + +Note that this code does *not* validate the type of `req.body.string`: + +- `req.body.string` is expected to be a string. If this is the case, all goes well. +- `req.body.string` is controlled by the client that sends the request. +- If `req.body.string` is the *number* `50`, the `rawBytes` would be 50 bytes: + - Before Node.js 8, the content would be uninitialized + - After Node.js 8, the content would be `50` bytes with the value `0` + +Because of the missing type check, an attacker could intentionally send a number +as part of the request. Using this, they can either: + +- Read uninitialized memory. This **will** leak passwords, encryption keys and other + kinds of sensitive information. (Information leak) +- Force the program to allocate a large amount of memory. For example, when specifying + `500000000` as the input value, each request will allocate 500MB of memory. + This can be used to either exhaust the memory available of a program completely + and make it crash, or slow it down significantly. (Denial of Service) + +Both of these scenarios are considered serious security issues in a real-world +web server context. + +when using `Buffer.from(req.body.string)` instead, passing a number will always +throw an exception instead, giving a controlled behaviour that can always be +handled by the program. + + +### The `Buffer()` constructor has been deprecated for a while. Is this really an issue? + +Surveys of code in the `npm` ecosystem have shown that the `Buffer()` constructor is still +widely used.

Adding in `safe-buffer` _magically removes the lint warning_, but the behavior +remains identiсal to what we had before, and when launched on Node.js 6.x LTS — this dumps out +chunks of uninitialized memory. +_And this code will still emit runtime warnings on Node.js 10.x and above._ + +That was done by design. I first considered changing `safe-buffer`, prohibiting old API usage or +emitting warnings on it, but that significantly diverges from `safe-buffer` design. After some +discussion, it was decided to move my approach into a separate package, and _this is that separate +package_. + +This footgun is not imaginary — I observed top-downloaded packages doing that kind of thing, +«fixing» the lint warning by blindly including `safe-buffer` without any actual changes. + +Also in some cases, even if the API _was_ migrated to use of safe Buffer API — a random pull request +can bring unsafe Buffer API usage back to the codebase by adding new calls — and that could go +unnoticed even if you have a linter prohibiting that (becase of the reason stated above), and even +pass CI. _I also observed that being done in popular packages._ + +Some examples: + * [webdriverio](https://github.com/webdriverio/webdriverio/commit/05cbd3167c12e4930f09ef7cf93b127ba4effae4#diff-124380949022817b90b622871837d56cR31) + (a module with 548 759 downloads/month), + * [websocket-stream](https://github.com/maxogden/websocket-stream/commit/c9312bd24d08271687d76da0fe3c83493871cf61) + (218 288 d/m, fix in [maxogden/websocket-stream#142](https://github.com/maxogden/websocket-stream/pull/142)), + * [node-serialport](https://github.com/node-serialport/node-serialport/commit/e8d9d2b16c664224920ce1c895199b1ce2def48c) + (113 138 d/m, fix in [node-serialport/node-serialport#1510](https://github.com/node-serialport/node-serialport/pull/1510)), + * [karma](https://github.com/karma-runner/karma/commit/3d94b8cf18c695104ca195334dc75ff054c74eec) + (3 973 193 d/m, fix in [karma-runner/karma#2947](https://github.com/karma-runner/karma/pull/2947)), + * [spdy-transport](https://github.com/spdy-http2/spdy-transport/commit/5375ac33f4a62a4f65bcfc2827447d42a5dbe8b1) + (5 970 727 d/m, fix in [spdy-http2/spdy-transport#53](https://github.com/spdy-http2/spdy-transport/pull/53)). + * And there are a lot more over the ecosystem. + +I filed a PR at +[mysticatea/eslint-plugin-node#110](https://github.com/mysticatea/eslint-plugin-node/pull/110) to +partially fix that (for cases when that lint rule is used), but it is a semver-major change for +linter rules and presets, so it would take significant time for that to reach actual setups. +_It also hasn't been released yet (2018-03-20)._ + +Also, `safer-buffer` discourages the usage of `.allocUnsafe()`, which is often done by a mistake. +It still supports it with an explicit concern barier, by placing it under +`require('safer-buffer/dangereous')`. + +## But isn't throwing bad? + +Not really.

The set +of primitive `operators` is: + +* `<` Less than +* `<=` Less than or equal to +* `>` Greater than +* `>=` Greater than or equal to +* `=` Equal. If no operator is specified, then equality is assumed, + so this operator is optional but MAY be included. + +For example, the comparator `>=1.2.7` would match the versions +`1.2.7`, `1.2.8`, `2.5.3`, and `1.3.9`, but not the versions `1.2.6` +or `1.1.0`. The comparator `>1` is equivalent to `>=2.0.0` and +would match the versions `2.0.0` and `3.1.0`, but not the versions +`1.0.1` or `1.1.0`. + +Comparators can be joined by whitespace to form a `comparator set`, +which is satisfied by the **intersection** of all of the comparators +it includes. + +A range is composed of one or more comparator sets, joined by `||`. A +version matches a range if and only if every comparator in at least +one of the `||`-separated comparator sets is satisfied by the version. + +For example, the range `>=1.2.7 <1.3.0` would match the versions +`1.2.7`, `1.2.8`, and `1.2.99`, but not the versions `1.2.6`, `1.3.0`, +or `1.1.0`. + +The range `1.2.7 || >=1.2.9 <2.0.0` would match the versions `1.2.7`, +`1.2.9`, and `1.4.6`, but not the versions `1.2.8` or `2.0.0`. + +### Prerelease Tags + +If a version has a prerelease tag (for example, `1.2.3-alpha.3`) then +it will only be allowed to satisfy comparator sets if at least one +comparator with the same `[major, minor, patch]` tuple also has a +prerelease tag. + +For example, the range `>1.2.3-alpha.3` would be allowed to match the +version `1.2.3-alpha.7`, but it would *not* be satisfied by +`3.4.5-alpha.9`, even though `3.4.5-alpha.9` is technically "greater +than" `1.2.3-alpha.3` according to the SemVer sort rules. The version +range only accepts prerelease tags on the `1.2.3` version. +Version `3.4.5` *would* satisfy the range because it does not have a +prerelease flag, and `3.4.5` is greater than `1.2.3-alpha.7`. + +The purpose of this behavior is twofold. First, prerelease versions +frequently are updated very quickly, and contain many breaking changes +that are (by the author's design) not yet fit for public consumption. +Therefore, by default, they are excluded from range-matching +semantics. + +Second, a user who has opted into using a prerelease version has +indicated the intent to use *that specific* set of +alpha/beta/rc versions. By including a prerelease tag in the range, +the user is indicating that they are aware of the risk. However, it +is still not appropriate to assume that they have opted into taking a +similar risk on the *next* set of prerelease versions. + +Note that this behavior can be suppressed (treating all prerelease +versions as if they were normal versions, for range-matching) +by setting the `includePrerelease` flag on the options +object to any +[functions](https://github.com/npm/node-semver#functions) that do +range matching. + +#### Prerelease Identifiers + +The method `.inc` takes an additional `identifier` string argument that +will append the value of the string as a prerelease identifier: + +```javascript +semver.inc('1.2.3', 'prerelease', 'beta') +// '1.2.4-beta.0' +``` + +command-line example: + +```bash +$ semver 1.2.3 -i prerelease --preid beta +1.2.4-beta.0 +``` + +Which then can be used to increment further: + +```bash +$ semver 1.2.4-beta.0 -i prerelease +1.2.4-beta.1 +``` + +#### Prerelease Identifier Base + +The method `.inc` takes an optional parameter 'identifierBase' string +that will let you let your prerelease number as zero-based or one-based. +Set to `false` to omit the prerelease number altogether. +If you do not specify this parameter, it will default to zero-based. + +```javascript +semver.inc('1.2.3', 'prerelease', 'beta', '1') +// '1.2.4-beta.1' +``` + +```javascript +semver.inc('1.2.3', 'prerelease', 'beta', false) +// '1.2.4-beta' +``` + +command-line example: + +```bash +$ semver 1.2.3 -i prerelease --preid beta -n 1 +1.2.4-beta.1 +``` + +```bash +$ semver 1.2.3 -i prerelease --preid beta -n false +1.2.4-beta +``` + +### Advanced Range Syntax + +Advanced range syntax desugars to primitive comparators in +deterministic ways. + +Advanced ranges may be combined in the same way as primitive +comparators using white space or `||`. + +#### Hyphen Ranges `X.Y.Z - A.B.C` + +Specifies an inclusive set. + +* `1.2.3 - 2.3.4` := `>=1.2.3 <=2.3.4` + +If a partial version is provided as the first version in the inclusive +range, then the missing pieces are replaced with zeroes. + +* `1.2 - 2.3.4` := `>=1.2.0 <=2.3.4` + +If a partial version is provided as the second version in the +inclusive range, then all versions that start with the supplied parts +of the tuple are accepted, but nothing that would be greater than the +provided tuple parts. + +* `1.2.3 - 2.3` := `>=1.2.3 <2.4.0-0` +* `1.2.3 - 2` := `>=1.2.3 <3.0.0-0` + +#### X-Ranges `1.2.x` `1.X` `1.2.*` `*` + +Any of `X`, `x`, or `*` may be used to "stand in" for one of the +numeric values in the `[major, minor, patch]` tuple. + +* `*` := `>=0.0.0` (Any non-prerelease version satisfies, unless + `includePrerelease` is specified, in which case any version at all + satisfies) +* `1.x` := `>=1.0.0 <2.0.0-0` (Matching major version) +* `1.2.x` := `>=1.2.0 <1.3.0-0` (Matching major and minor versions) + +A partial version range is treated as an X-Range, so the special +character is in fact optional. + +* `""` (empty string) := `*` := `>=0.0.0` +* `1` := `1.x.x` := `>=1.0.0 <2.0.0-0` +* `1.2` := `1.2.x` := `>=1.2.0 <1.3.0-0` + +#### Tilde Ranges `~1.2.3` `~1.2` `~1` + +Allows patch-level changes if a minor version is specified on the +comparator.

All +options in this object are `false` by default. The options supported +are: + +- `loose`: Be more forgiving about not-quite-valid semver strings. + (Any resulting output will always be 100% strict compliant, of + course.) For backwards compatibility reasons, if the `options` + argument is a boolean value instead of an object, it is interpreted + to be the `loose` param. +- `includePrerelease`: Set to suppress the [default + behavior](https://github.com/npm/node-semver#prerelease-tags) of + excluding prerelease tagged versions from ranges unless they are + explicitly opted into. + +Strict-mode Comparators and Ranges will be strict about the SemVer +strings that they parse. + +* `valid(v)`: Return the parsed version, or null if it's not valid. +* `inc(v, release, options, identifier, identifierBase)`: + Return the version incremented by the release + type (`major`, `premajor`, `minor`, `preminor`, `patch`, + `prepatch`, or `prerelease`), or null if it's not valid + * `premajor` in one call will bump the version up to the next major + version and down to a prerelease of that major version. + `preminor`, and `prepatch` work the same way. + * If called from a non-prerelease version, `prerelease` will work the + same as `prepatch`. It increments the patch version and then makes a + prerelease. If the input version is already a prerelease it simply + increments it. + * `identifier` can be used to prefix `premajor`, `preminor`, + `prepatch`, or `prerelease` version increments. `identifierBase` + is the base to be used for the `prerelease` identifier. +* `prerelease(v)`: Returns an array of prerelease components, or null + if none exist. Example: `prerelease('1.2.3-alpha.1') -> ['alpha', 1]` +* `major(v)`: Return the major version number. +* `minor(v)`: Return the minor version number. +* `patch(v)`: Return the patch version number. +* `intersects(r1, r2, loose)`: Return true if the two supplied ranges + or comparators intersect. +* `parse(v)`: Attempt to parse a string as a semantic version, returning either + a `SemVer` object or `null`. + +### Comparison + +* `gt(v1, v2)`: `v1 > v2` +* `gte(v1, v2)`: `v1 >= v2` +* `lt(v1, v2)`: `v1 < v2` +* `lte(v1, v2)`: `v1 <= v2` +* `eq(v1, v2)`: `v1 == v2` This is true if they're logically equivalent, + even if they're not the same string. You already know how to + compare strings. +* `neq(v1, v2)`: `v1 != v2` The opposite of `eq`. +* `cmp(v1, comparator, v2)`: Pass in a comparison string, and it'll call + the corresponding function above. `"==="` and `"!=="` do simple + string comparison, but are included for completeness. Throws if an + invalid comparison string is provided. +* `compare(v1, v2)`: Return `0` if `v1 == v2`, or `1` if `v1` is greater, or `-1` if + `v2` is greater. Sorts in ascending order if passed to `Array.sort()`. +* `rcompare(v1, v2)`: The reverse of `compare`. Sorts an array of versions + in descending order when passed to `Array.sort()`. +* `compareBuild(v1, v2)`: The same as `compare` but considers `build` when two versions + are equal. Sorts in ascending order if passed to `Array.sort()`. +* `compareLoose(v1, v2)`: Short for `compare(v1, v2, { loose: true })`. +* `diff(v1, v2)`: Returns the difference between two versions by the release type + (`major`, `premajor`, `minor`, `preminor`, `patch`, `prepatch`, or `prerelease`), + or null if the versions are the same. + +### Sorting + +* `sort(versions)`: Returns a sorted array of versions based on the `compareBuild` + function. +* `rsort(versions)`: The reverse of `sort`. Returns an array of versions based on + the `compareBuild` function in descending order. + +### Comparators + +* `intersects(comparator)`: Return true if the comparators intersect + +### Ranges + +* `validRange(range)`: Return the valid range or null if it's not valid +* `satisfies(version, range)`: Return true if the version satisfies the + range. +* `maxSatisfying(versions, range)`: Return the highest version in the list + that satisfies the range, or `null` if none of them do. +* `minSatisfying(versions, range)`: Return the lowest version in the list + that satisfies the range, or `null` if none of them do. +* `minVersion(range)`: Return the lowest version that can match + the given range. +* `gtr(version, range)`: Return `true` if the version is greater than all the + versions possible in the range. +* `ltr(version, range)`: Return `true` if the version is less than all the + versions possible in the range. +* `outside(version, range, hilo)`: Return true if the version is outside + the bounds of the range in either the high or low direction. The + `hilo` argument must be either the string `'>'` or `'<'`. (This is + the function called by `gtr` and `ltr`.) +* `intersects(range)`: Return true if any of the range comparators intersect. +* `simplifyRange(versions, range)`: Return a "simplified" range that + matches the same items in the `versions` list as the range specified. Note + that it does *not* guarantee that it would match the same versions in all + cases, only for the set of versions provided. This is useful when + generating ranges by joining together multiple versions with `||` + programmatically, to provide the user with something a bit more + ergonomic. If the provided range is shorter in string-length than the + generated range, then that is returned. +* `subset(subRange, superRange)`: Return `true` if the `subRange` range is + entirely contained by the `superRange` range. + +Note that, since ranges may be non-contiguous, a version might not be +greater than a range, less than a range, *or* satisfy a range! For +example, the range `1.2 <1.2.9 || >2.0.0` would have a hole from `1.2.9` +until `2.0.0`, so version `1.2.10` would not be greater than the +range (because `2.0.1` satisfies, which is higher), nor less than the +range (since `1.2.8` satisfies, which is lower), and it also does not +satisfy the range. + +If you want to know if a version satisfies or does not satisfy a +range, use the `satisfies(version, range)` function. + +### Coercion + +* `coerce(version, options)`: Coerces a string to semver if possible + +This aims to provide a very forgiving translation of a non-semver string to +semver. It looks for the first digit in a string and consumes all +remaining characters which satisfy at least a partial semver (e.g., `1`, +`1.2`, `1.2.3`) up to the max permitted length (256 characters). Longer +versions are simply truncated (`4.6.3.9.2-alpha2` becomes `4.6.3`). All +surrounding text is simply ignored (`v3.4 replaces v3.3.1` becomes +`3.4.0`). Only text which lacks digits will fail coercion (`version one` +is not valid). The maximum length for any semver component considered for +coercion is 16 characters; longer components will be ignored +(`10000000000000000.4.7.4` becomes `4.7.4`). The maximum value for any +semver component is `Number.MAX_SAFE_INTEGER || (2**53 - 1)`; higher value +components are invalid (`9999999999999999.4.7.4` is likely invalid). + +If the `options.rtl` flag is set, then `coerce` will return the right-most +coercible tuple that does not share an ending index with a longer coercible +tuple. For example, `1.2.3.4` will return `2.3.4` in rtl mode, not +`4.0.0`. `1.2.3/4` will return `4.0.0`, because the `4` is not a part of +any other overlapping SemVer tuple. + +If the `options.includePrerelease` flag is set, then the `coerce` result will contain +prerelease and build parts of a version. For example, `1.2.3.4-rc.1+rev.2` +will preserve prerelease `rc.1` and build `rev.2` in the result. + +### Clean + +* `clean(version)`: Clean a string to be a valid semver if possible + +This will return a cleaned and trimmed semver version. If the provided +version is not valid a null will be returned. This does not work for +ranges. + +ex. +* `s.clean(' = v 2.1.5foo')`: `null` +* `s.clean(' = v 2.1.5foo', { loose: true })`: `'2.1.5-foo'` +* `s.clean(' = v 2.1.5-foo')`: `null` +* `s.clean(' = v 2.1.5-foo', { loose: true })`: `'2.1.5-foo'` +* `s.clean('=v2.1.5')`: `'2.1.5'` +* `s.clean(' =v2.1.5')`: `'2.1.5'` +* `s.clean(' 2.1.5 ')`: `'2.1.5'` +* `s.clean('~1.0.0')`: `null` + +## Constants + +As a convenience, helper constants are exported to provide information about what `node-semver` supports: + +### `RELEASE_TYPES` + +- major +- premajor +- minor +- preminor +- patch +- prepatch +- prerelease + +``` +const semver = require('semver'); + +if (semver.RELEASE_TYPES.includes(arbitraryUserInput)) { + console.log('This is a valid release type!'); +} else { + console.warn('This is NOT a valid release type!'); +} +``` + +### `SEMVER_SPEC_VERSION` + +2.0.0 + +``` +const semver = require('semver'); + +console.log('We are currently using the semver specification version:', semver.SEMVER_SPEC_VERSION); +``` + +## Exported Modules + + + +You may pull in just the part of this semver utility that you need if you +are sensitive to packing and tree-shaking concerns.

The `req` is +the Node.js HTTP request and the `path` is a urlencoded path to send (urlencoded, +not the actual file-system path). + +#### Options + +##### acceptRanges + +Enable or disable accepting ranged requests, defaults to true. +Disabling this will not send `Accept-Ranges` and ignore the contents +of the `Range` request header. + +##### cacheControl + +Enable or disable setting `Cache-Control` response header, defaults to +true. Disabling this will ignore the `immutable` and `maxAge` options. + +##### dotfiles + +Set how "dotfiles" are treated when encountered. A dotfile is a file +or directory that begins with a dot ("."). Note this check is done on +the path itself without checking if the path actually exists on the +disk. If `root` is specified, only the dotfiles above the root are +checked (i.e. the root itself can be within a dotfile when when set +to "deny"). + + - `'allow'` No special treatment for dotfiles. + - `'deny'` Send a 403 for any request for a dotfile. + - `'ignore'` Pretend like the dotfile does not exist and 404. + +The default value is _similar_ to `'ignore'`, with the exception that +this default will not ignore the files within a directory that begins +with a dot, for backward-compatibility. + +##### end + +Byte offset at which the stream ends, defaults to the length of the file +minus 1. The end is inclusive in the stream, meaning `end: 3` will include +the 4th byte in the stream. + +##### etag + +Enable or disable etag generation, defaults to true. + +##### extensions + +If a given file doesn't exist, try appending one of the given extensions, +in the given order. By default, this is disabled (set to `false`). An +example value that will serve extension-less HTML files: `['html', 'htm']`. +This is skipped if the requested file already has an extension. + +##### immutable + +Enable or disable the `immutable` directive in the `Cache-Control` response +header, defaults to `false`. If set to `true`, the `maxAge` option should +also be specified to enable caching. The `immutable` directive will prevent +supported clients from making conditional requests during the life of the +`maxAge` option to check if the file has changed. + +##### index + +By default send supports "index.html" files, to disable this +set `false` or to supply a new index pass a string or an array +in preferred order. + +##### lastModified + +Enable or disable `Last-Modified` header, defaults to true. Uses the file +system's last modified value. + +##### maxAge + +Provide a max-age in milliseconds for http caching, defaults to 0. +This can also be a string accepted by the +[ms](https://www.npmjs.org/package/ms#readme) module. + +##### root + +Serve files relative to `path`. + +##### start + +Byte offset at which the stream starts, defaults to 0. The start is inclusive, +meaning `start: 2` will include the 3rd byte in the stream. + +#### Events + +The `SendStream` is an event emitter and will emit the following events: + + - `error` an error occurred `(err)` + - `directory` a directory was requested `(res, path)` + - `file` a file was requested `(path, stat)` + - `headers` the headers are about to be set on a file `(res, path, stat)` + - `stream` file streaming has started `(stream)` + - `end` streaming has completed + +#### .pipe + +The `pipe` method is used to pipe the response into the Node.js HTTP response +object, typically `send(req, path, options).pipe(res)`. + +### .mime + +The `mime` export is the global instance of of the +[`mime` npm module](https://www.npmjs.com/package/mime). + +This is used to configure the MIME types that are associated with file extensions +as well as other options for how to resolve the MIME type of a file (like the +default type to use for an unknown file extension). + +## Error-handling + +By default when no `error` listeners are present an automatic response will be +made, otherwise you have full control over the response, aka you may show a 5xx +page etc. + +## Caching + +It does _not_ perform internal caching, you should use a reverse proxy cache +such as Varnish for this, or those fancy things called CDNs.

The file to serve will be determined by combining `req.url` +with the provided root directory. When a file is not found, instead of +sending a 404 response, this module will instead call `next()` to move on +to the next middleware, allowing for stacking and fall-backs. + +#### Options + +##### acceptRanges + +Enable or disable accepting ranged requests, defaults to true. +Disabling this will not send `Accept-Ranges` and ignore the contents +of the `Range` request header. + +##### cacheControl + +Enable or disable setting `Cache-Control` response header, defaults to +true. Disabling this will ignore the `immutable` and `maxAge` options. + +##### dotfiles + + Set how "dotfiles" are treated when encountered. A dotfile is a file +or directory that begins with a dot ("."). Note this check is done on +the path itself without checking if the path actually exists on the +disk. If `root` is specified, only the dotfiles above the root are +checked (i.e. the root itself can be within a dotfile when set +to "deny"). + + - `'allow'` No special treatment for dotfiles. + - `'deny'` Deny a request for a dotfile and 403/`next()`. + - `'ignore'` Pretend like the dotfile does not exist and 404/`next()`. + +The default value is similar to `'ignore'`, with the exception that this +default will not ignore the files within a directory that begins with a dot. + +##### etag + +Enable or disable etag generation, defaults to true. + +##### extensions + +Set file extension fallbacks. When set, if a file is not found, the given +extensions will be added to the file name and search for. The first that +exists will be served. Example: `['html', 'htm']`. + +The default value is `false`. + +##### fallthrough + +Set the middleware to have client errors fall-through as just unhandled +requests, otherwise forward a client error. The difference is that client +errors like a bad request or a request to a non-existent file will cause +this middleware to simply `next()` to your next middleware when this value +is `true`. When this value is `false`, these errors (even 404s), will invoke +`next(err)`. + +Typically `true` is desired such that multiple physical directories can be +mapped to the same web address or for routes to fill in non-existent files. + +The value `false` can be used if this middleware is mounted at a path that +is designed to be strictly a single file system directory, which allows for +short-circuiting 404s for less overhead. This middleware will also reply to +all methods. + +The default value is `true`. + +##### immutable + +Enable or disable the `immutable` directive in the `Cache-Control` response +header, defaults to `false`. If set to `true`, the `maxAge` option should +also be specified to enable caching. The `immutable` directive will prevent +supported clients from making conditional requests during the life of the +`maxAge` option to check if the file has changed. + +##### index + +By default this module will send "index.html" files in response to a request +on a directory. To disable this set `false` or to supply a new index pass a +string or an array in preferred order. + +##### lastModified + +Enable or disable `Last-Modified` header, defaults to true. Uses the file +system's last modified value. + +##### maxAge + +Provide a max-age in milliseconds for http caching, defaults to 0. This +can also be a string accepted by the [ms](https://www.npmjs.org/package/ms#readme) +module. + +##### redirect + +Redirect to trailing "/" when the pathname is a dir. Defaults to `true`. + +##### setHeaders + +Function to set custom headers on response. Alterations to the headers need to +occur synchronously. The function is called as `fn(res, path, stat)`, where +the arguments are: + + - `res` the response object + - `path` the file path that is being sent + - `stat` the stat object of the file that is being sent + +## Examples + +### Serve files with vanilla node.js http server + +```js +var finalhandler = require('finalhandler') +var http = require('http') +var serveStatic = require('serve-static') + +// Serve up public/ftp folder +var serve = serveStatic('public/ftp', { index: ['index.html', 'index.htm'] }) + +// Create server +var server = http.createServer(function onRequest (req, res) { + serve(req, res, finalhandler(req, res)) +}) + +// Listen +server.listen(3000) +``` + +### Serve all files as downloads + +```js +var contentDisposition = require('content-disposition') +var finalhandler = require('finalhandler') +var http = require('http') +var serveStatic = require('serve-static') + +// Serve up public/ftp folder +var serve = serveStatic('public/ftp', { + index: false, + setHeaders: setHeaders +}) + +// Set header to force download +function setHeaders (res, path) { + res.setHeader('Content-Disposition', contentDisposition(path)) +} + +// Create server +var server = http.createServer(function onRequest (req, res) { + serve(req, res, finalhandler(req, res)) +}) + +// Listen +server.listen(3000) +``` + +### Serving using express + +#### Simple + +This is a simple example of using Express. + +```js +var express = require('express') +var serveStatic = require('serve-static') + +var app = express() + +app.use(serveStatic('public/ftp', { index: ['default.html', 'default.htm'] })) +app.listen(3000) +``` + +#### Multiple roots + +This example shows a simple way to search through multiple directories. +Files are searched for in `public-optimized/` first, then `public/` second +as a fallback. + +```js +var express = require('express') +var path = require('path') +var serveStatic = require('serve-static') + +var app = express() + +app.use(serveStatic(path.join(__dirname, 'public-optimized'))) +app.use(serveStatic(path.join(__dirname, 'public'))) +app.listen(3000) +``` + +#### Different settings for paths + +This example shows how to set a different max age depending on the served +file type.

+What does this do? + +
+ +This libary generates the `source` string to be passed to `new RegExp()` for matching a range of numbers. + +**Example** + +```js +const toRegexRange = require('to-regex-range'); +const regex = new RegExp(toRegexRange('15', '95')); +``` + +A string is returned so that you can do whatever you need with it before passing it to `new RegExp()` (like adding `^` or `$` boundaries, defining flags, or combining it another string). + +
+ +
+ +
+Why use this library? + +
+ +### Convenience + +Creating regular expressions for matching numbers gets deceptively complicated pretty fast. + +For example, let's say you need a validation regex for matching part of a user-id, postal code, social security number, tax id, etc: + +* regex for matching `1` => `/1/` (easy enough) +* regex for matching `1` through `5` => `/[1-5]/` (not bad...) +* regex for matching `1` or `5` => `/(1|5)/` (still easy...) +* regex for matching `1` through `50` => `/([1-9]|[1-4][0-9]|50)/` (uh-oh...) +* regex for matching `1` through `55` => `/([1-9]|[1-4][0-9]|5[0-5])/` (no prob, I can do this...) +* regex for matching `1` through `555` => `/([1-9]|[1-9][0-9]|[1-4][0-9]{2}|5[0-4][0-9]|55[0-5])/` (maybe not...) +* regex for matching `0001` through `5555` => `/(0{3}[1-9]|0{2}[1-9][0-9]|0[1-9][0-9]{2}|[1-4][0-9]{3}|5[0-4][0-9]{2}|55[0-4][0-9]|555[0-5])/` (okay, I get the point!) + +The numbers are contrived, but they're also really basic. In the real world you might need to generate a regex on-the-fly for validation. + +**Learn more** + +If you're interested in learning more about [character classes](http://www.regular-expressions.info/charclass.html) and other regex features, I personally have always found [regular-expressions.info](http://www.regular-expressions.info/charclass.html) to be pretty useful. + +### Heavily tested + +As of April 07, 2019, this library runs [>1m test assertions](./test/test.js) against generated regex-ranges to provide brute-force verification that results are correct. + +Tests run in ~280ms on my MacBook Pro, 2.5 GHz Intel Core i7. + +### Optimized + +Generated regular expressions are optimized: + +* duplicate sequences and character classes are reduced using quantifiers +* smart enough to use `?` conditionals when number(s) or range(s) can be positive or negative +* uses fragment caching to avoid processing the same exact string more than once + +
+ +
+ +## Usage + +Add this library to your javascript application with the following line of code + +```js +const toRegexRange = require('to-regex-range'); +``` + +The main export is a function that takes two integers: the `min` value and `max` value (formatted as strings or numbers). + +```js +const source = toRegexRange('15', '95'); +//=> 1[5-9]|[2-8][0-9]|9[0-5] + +const regex = new RegExp(`^${source}$`); +console.log(regex.test('14')); //=> false +console.log(regex.test('50')); //=> true +console.log(regex.test('94')); //=> true +console.log(regex.test('96')); //=> false +``` + +## Options + +### options.capture + +**Type**: `boolean` + +**Deafault**: `undefined` + +Wrap the returned value in parentheses when there is more than one regex condition.
