Bumps github.com/evanw/esbuild from 0.12.10 to 0.19.3.

Release notes

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

v0.19.3

• Fix list-style-type with the local-css loader (#3325)

  The local-css loader incorrectly treated all identifiers provided to list-style-type as a custom local identifier. That included identifiers such as none which have special meaning in CSS, and which should not be treated as custom local identifiers. This release fixes this bug:

  /* Original code */
  ul { list-style-type: none }
  /* Old output (with --loader=local-css) */
  ul {
  list-style-type: stdin_none;
  }
  /* New output (with --loader=local-css) */
  ul {
  list-style-type: none;
  }
  

  Note that this bug only affected code using the local-css loader. It did not affect code using the css loader.

• Avoid inserting temporary variables before use strict (#3322)

  This release fixes a bug where esbuild could incorrectly insert automatically-generated temporary variables before use strict directives:

  // Original code
  function foo() {
    'use strict'
    a.b?.c()
  }
  // Old output (with --target=es6)
  function foo() {
  var _a;
  "use strict";
  (_a = a.b) == null ? void 0 : _a.c();
  }
  // New output (with --target=es6)
  function foo() {
  "use strict";
  var _a;
  (_a = a.b) == null ? void 0 : _a.c();
  }
  

• Adjust TypeScript enum output to better approximate tsc (#3329)

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.
