Bump esbuild and esbuild-loader

[dependabot]

Bumps esbuild to 0.27.2 and updates ancestor dependency esbuild-loader. These dependencies need to be updated together.

Updates esbuild from 0.11.20 to 0.27.2

Release notes

Sourced from esbuild's releases.

v0.27.2

• Allow import path specifiers starting with #/ (#4361)

  Previously the specification for package.json disallowed import path specifiers starting with #/, but this restriction has recently been relaxed and support for it is being added across the JavaScript ecosystem. One use case is using it for a wildcard pattern such as mapping #/* to ./src/* (previously you had to use another character such as #_* instead, which was more confusing). There is some more context in nodejs/node#49182.

  This change was contributed by @​hybrist.

• Automatically add the -webkit-mask prefix (#4357, #4358)

  This release automatically adds the -webkit- vendor prefix for the mask CSS shorthand property:

  /* Original code */
  main {
    mask: url(x.png) center/5rem no-repeat
  }
  /* Old output (with --target=chrome110) */
  main {
  mask: url(x.png) center/5rem no-repeat;
  }
  /* New output (with --target=chrome110) */
  main {
  -webkit-mask: url(x.png) center/5rem no-repeat;
  mask: url(x.png) center/5rem no-repeat;
  }

  This change was contributed by @​BPJEnnova.

• Additional minification of switch statements (#4176, #4359)

  This release contains additional minification patterns for reducing switch statements. Here is an example:

  // Original code
  switch (x) {
    case 0:
      foo()
      break
    case 1:
    default:
      bar()
  }
  // Old output (with --minify)
  switch(x){case 0:foo();break;case 1:default:bar()}
  // New output (with --minify)

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.
