[dependabot]

Bumps esbuild-wasm from 0.8.27 to 0.17.6.

Release notes

Sourced from esbuild-wasm's releases.

v0.17.6

• Fix a CSS parser crash on invalid CSS (#2892)

  Previously the following invalid CSS caused esbuild's parser to crash:

  @media screen

  The crash was caused by trying to construct a helpful error message assuming that there was an opening { token, which is not the case here. This release fixes the crash.

• Inline TypeScript enums that are referenced before their declaration

  Previously esbuild inlined enums within a TypeScript file from top to bottom, which meant that references to TypeScript enum members were only inlined within the same file if they came after the enum declaration. With this release, esbuild will now inline enums even when they are referenced before they are declared:

  // Original input
  export const foo = () => Foo.FOO
  const enum Foo { FOO = 0 }
  // Old output (with --tree-shaking=true)
  export const foo = () => Foo.FOO;
  var Foo = /* @PURE */ ((Foo2) => {
  Foo2[Foo2["FOO"] = 0] = "FOO";
  return Foo2;
  })(Foo || {});
  // New output (with --tree-shaking=true)
  export const foo = () => 0 /* FOO */;

  This makes esbuild's TypeScript output smaller and faster when processing code that does this. I noticed this issue when I ran the TypeScript compiler's source code through esbuild's bundler. Now that the TypeScript compiler is going to be bundled with esbuild in the upcoming TypeScript 5.0 release, improvements like this will also improve the TypeScript compiler itself!

• Fix esbuild installation on Arch Linux (#2785, #2812, #2865)

  Someone made an unofficial esbuild package for Linux that adds the ESBUILD_BINARY_PATH=/usr/bin/esbuild environment variable to the user's default environment. This breaks all npm installations of esbuild for users with this unofficial Linux package installed, which has affected many people. Most (all?) people who encounter this problem haven't even installed this unofficial package themselves; instead it was installed for them as a dependency of another Linux package. The problematic change to add the ESBUILD_BINARY_PATH environment variable was reverted in the latest version of this unofficial package. However, old versions of this unofficial package are still there and will be around forever. With this release, ESBUILD_BINARY_PATH is now ignored by esbuild's install script when it's set to the value /usr/bin/esbuild. This should unbreak using npm to install esbuild in these problematic Linux environments.

  Note: The ESBUILD_BINARY_PATH variable is an undocumented way to override the location of esbuild's binary when esbuild's npm package is installed, which is necessary to substitute your own locally-built esbuild binary when debugging esbuild's npm package. It's only meant for very custom situations and should absolutely not be forced on others by default, especially without their knowledge. I may remove the code in esbuild's installer that reads ESBUILD_BINARY_PATH in the future to prevent these kinds of issues. It will unfortunately make debugging esbuild harder. If ESBUILD_BINARY_PATH is ever removed, it will be done in a "breaking change" release.

v0.17.5

• Parse const type parameters from TypeScript 5.0

  The TypeScript 5.0 beta announcement adds const type parameters to the language. You can now add the const modifier on a type parameter of a function, method, or class like this:

  type HasNames = { names: readonly string[] };
  const getNamesExactly = <const T extends HasNames>(arg: T): T["names"] => arg.names;
  const names = getNamesExactly({ names: ["Alice", "Bob", "Eve"] });

Changelog: 2020

This changelog documents all esbuild versions published in the year 2020 (versions 0.3.0 through 0.8.28).

0.8.28

• Add a --summary flag that prints helpful information after a build (#631)

  Normally esbuild's CLI doesn't print anything after doing a build if nothing went wrong. This allows esbuild to be used as part of a more complex chain of tools without the output cluttering the terminal. However, sometimes it is nice to have a quick overview in your terminal of what the build just did. You can now add the --summary flag when using the CLI and esbuild will print a summary of what the build generated. It looks something like this:

  $ ./esbuild --summary --bundle src/Three.js --outfile=build/three.js --sourcemap
  build/three.js      1.0mb ⚠️
  build/three.js.map  1.8mb
  ⚡ Done in 43ms
  

• Keep unused imports in TypeScript code in one specific case (#604)

  The official TypeScript compiler always removes imported symbols that aren't used as values when converting TypeScript to JavaScript. This is because these symbols could be types and not removing them could result in a run-time module instantiation failure because of missing exports. This even happens when the tsconfig.json setting "importsNotUsedAsValues" is set to "preserve". Doing this just keeps the import statement itself but confusingly still removes the imports that aren't used as values.

  Previously esbuild always exactly matched the behavior of the official TypeScript compiler regarding import removal. However, that is problematic when trying to use esbuild to compile a partial module such as when converting TypeScript to JavaScript inside a file written in the Svelte programming language. Here is an example:

  <script lang="ts">
    import Counter from './Counter.svelte';
    export let name: string = 'world';
  </script>
  <main>
    <h1>Hello {name}!</h1>
    <Counter />
  </main>

  The current Svelte compiler plugin for TypeScript only provides esbuild with the contents of the <script> tag so to esbuild, the import Counter appears to be unused and is removed.

  In this release, esbuild deliberately deviates from the behavior of the official TypeScript compiler if all of these conditions are met:

  • The "importsNotUsedAsValues" field in tsconfig.json must be present and must not be set to "remove". This is necessary because this is the only case where esbuild can assume that all imports are values instead of types. Any imports that are types will cause a type error when the code is run through the TypeScript type checker. To import types when the importsNotUsedAsValues setting is active, you must use the TypeScript-specific import type syntax instead.

  • You must not be using esbuild as a bundler. When bundling, esbuild needs to assume that it's not seeing a partial file because the bundling process requires renaming symbols to avoid cross-file name collisions.

  • You must not have identifier minification enabled. It's useless to preserve unused imports in this case because referencing them by name won't work anyway. And keeping the unused imports would be counter-productive to minification since they would be extra unnecessary data in the output file.

  This should hopefully allow esbuild to be used as a TypeScript-to-JavaScript converter for programming languages such as Svelte, at least in many cases. The build pipeline in esbuild wasn't designed for compiling partial modules and this still won't be a fully robust solution (e.g. some variables may be renamed to avoid name collisions in rare cases). But it's possible that these cases are very unlikely to come up in practice. Basically this change to keep unused imports in this case should be useful at best and harmless at worst.
