CPR (cp -R)

There are other modules out there that attempt this, but none did it the way I needed it to be done or they had issues and the author failed to fix them in a timely manner.

Install

npm install cpr

Build Status

Usage

var cpr = require('cpr');
//or
var cpr = require('cpr').cpr; //Back compat

cpr('/path/from', '/path/to', {
    deleteFirst: true, //Delete "to" before
    overwrite: true, //If the file exists, overwrite it
    confirm: true //After the copy, stat all the copied files to make sure they are there
}, function(err, files) {
    //err - The error if any (err.list might be available with an array of errors for more detailed information)
    //files - List of files that we copied
});

cpr('/path/from', '/path/to', function(err, files) {
    //err - The error if any (err.list might be available with an array of errors for more detailed information)
    //      In the case of an error, cpr continues to copy files but returns this error object with all of the files that it failed to copy.
    //files - List of files that we copied
});

Options

All options default to false.

• deleteFirst: Delete the to directory with rimraf
• overwrite: If the destination exists, overwrite it
• confirm: After the copy operation, stat all the files and report errors if any are missing
• filter: RegExp or function to test each file against before copying

Filtering

If you give it a RegExp, it will use that to test the filename as they are being gathered. If it passes, it will be removed. If you give it a function, it will use that with Array.filter on the list of files.

CLI

cpr can also be used from the command line which is useful for cross platform support.

Usage:

cpr <source> <destination> [options]

Copies files from source to destination.

Options:

• -d, --delete-first: Delete the destination directory before copying.
• -f <regex>, --filter <regex>: Filter out any items that match <regex>, a case-insensitive regex pattern.
• -h, --help: Display this usage info.
• -o, --overwrite: Overwrite the destination exists if it exists.
• -v, --version: Display the cpr version.

Note that the CLI's filter option is simpler than the original NodeJS API, only accepting case-insensitive regular expression patterns and not functions.
