Bumps github.com/evanw/esbuild from 0.12.10 to 0.17.3.

Release notes

Sourced from github.com/evanw/esbuild's releases.

v0.17.3

• Fix incorrect CSS minification for certain rules (#2838)

  Certain rules such as @media could previously be minified incorrectly. Due to a typo in the duplicate rule checker, two known @-rules that share the same hash code were incorrectly considered to be equal. This problem was made worse by the rule hashing code considering two unknown declarations (such as CSS variables) to have the same hash code, which also isn't optimal from a performance perspective. Both of these issues have been fixed:

  /* Original input */
  @media (prefers-color-scheme: dark) { body { --VAR-1: [#000](https://github.com/evanw/esbuild/issues/000); } }
  @media (prefers-color-scheme: dark) { body { --VAR-2: [#000](https://github.com/evanw/esbuild/issues/000); } }
  /* Old output (with --minify) */
  @​media (prefers-color-scheme: dark){body{--VAR-2: #000}}
  /* New output (with --minify) */
  @​media (prefers-color-scheme: dark){body{--VAR-1: #000}}@​media (prefers-color-scheme: dark){body{--VAR-2: #000}}
  

v0.17.2

• Add onDispose to the plugin API (#2140, #2205)

  If your plugin wants to perform some cleanup after it's no longer going to be used, you can now use the onDispose API to register a callback for cleanup-related tasks. For example, if a plugin starts a long-running child process then it may want to terminate that process when the plugin is discarded. Previously there was no way to do this. Here's an example:

  let examplePlugin = {
    name: 'example',
    setup(build) {
      build.onDispose(() => {
        console.log('This plugin is no longer used')
      })
    },
  }
  

  These onDispose callbacks will be called after every build() call regardless of whether the build failed or not as well as after the first dispose() call on a given build context.

v0.17.1

• Make it possible to cancel a build (#2725)

  The context object introduced in version 0.17.0 has a new cancel() method. You can use it to cancel a long-running build so that you can start a new one without needing to wait for the previous one to finish. When this happens, the previous build should always have at least one error and have no output files (i.e. it will be a failed build).

  Using it might look something like this:

  • JS:

    let ctx = await esbuild.context({
      // ...
    })
    let rebuildWithTimeLimit = timeLimit => {

Changelog

Changelog: 2021

This changelog documents all esbuild versions published in the year 2021 (versions 0.8.29 through 0.14.10).

0.14.10

• Enable tree shaking of classes with lowered static fields (#175)

  If the configured target environment doesn't support static class fields, they are converted into a call to esbuild's __publicField function instead. However, esbuild's tree-shaking pass treated this call as a side effect, which meant that all classes with static fields were ineligible for tree shaking. This release fixes the problem by explicitly ignoring calls to the __publicField function during tree shaking side-effect determination. Tree shaking is now enabled for these classes:

  // Original code
  class Foo { static foo = 'foo' }
  class Bar { static bar = 'bar' }
  new Bar()
  // Old output (with --tree-shaking=true --target=es6)
  class Foo {
  }
  __publicField(Foo, "foo", "foo");
  class Bar {
  }
  __publicField(Bar, "bar", "bar");
  new Bar();
  // New output (with --tree-shaking=true --target=es6)
  class Bar {
  }
  __publicField(Bar, "bar", "bar");
  new Bar();
  

• Treat --define:foo=undefined as an undefined literal instead of an identifier (#1407)

  References to the global variable undefined are automatically replaced with the literal value for undefined, which appears as void 0 when printed. This allows for additional optimizations such as collapsing undefined ?? bar into just bar. However, this substitution was not done for values specified via --define:. As a result, esbuild could potentially miss out on certain optimizations in these cases. With this release, it's now possible to use --define: to substitute something with an undefined literal:

  // Original code
  let win = typeof window !== 'undefined' ? window : {}
  // Old output (with --define:window=undefined --minify)
  let win=typeof undefined!="undefined"?undefined:{};
  // New output (with --define:window=undefined --minify)
  let win={};
  

• Add the --drop:debugger flag (#1809)

  Passing this flag causes all debugger; statements to be removed from the output. This is similar to the drop_debugger: true flag available in the popular UglifyJS and Terser JavaScript minifiers.
