[dependabot]

Bumps the npm_and_yarn group with 1 update in the / directory: esbuild.

Updates esbuild from 0.20.2 to 0.28.2

Release notes

Sourced from esbuild's releases.

v0.28.2

• Fix tree shaking bug due to TypeScript import alias (#4507)

  This release fixes a bug that could cause esbuild to incorrectly tree-shake imports that are used in a TypeScript type alias under certain circumstances. Affected code uses a TypeScript-specific import assignment and looks something like this:

  import Base from './dep.js';
  import Alias = Base.SomeType;

• Fix CSS minification bug involving & (#4497)

  This release fixes a bug where esbuild's CSS minifier incorrectly removed a & when it was unsafe to do so. Here is an example:

  /* Original code */
  .a .b {
    & .b:not(& .c) {
      color: red;
    }
  }
  /* Old output (with --minify) */
  .a .b{.b:not(& .c){color:red}}
  /* New output (with --minify) */
  .a .b{& .b:not(& .c){color:red}}

  This should match <span class="a"><span class="b"><span class="b">yes</span></span></span> but not <span class="a"><span class="b">no</span></span>. The old output incorrectly matched both.

• Avoid overwriting input files without --allow-overwrite (#4484)

  For example: esbuild input.js --outfile=input.js tells esbuild to overwrite input.js with the output of running esbuild on it. This was supposed to already be prevented by default, but it accidentally regressed in version 0.17.0 and apparently didn't have any test coverage. The error message was being printed but the input file was still being overwritten. Oops.

  This release puts the original behavior back. With this release, esbuild should now actually avoid overwriting input files unless --allow-overwrite is explicitly present. This is done by not writing out any files when a build error is encountered.

• Fix incorrect code generated when using top-level await (#4498)

  Previously esbuild could generate code containing a syntax error in complex scenarios involving top-level await used in a dependency cycle. The problem was a missing async on one or more module wrapper closures. With this release, esbuild now uses a fixed-point iteration algorithm to correctly annotate all dependencies in the cycle as needing an async module wrapper.

• Fix a minification bug with lowered logical assignment operators (#4508)

  This release fixes a bug that could cause esbuild to generate incorrect code for logical assignment operators when lowering them to an older target environment. Specifically the lowering process requires duplicating the left-hand side, but esbuild incorrectly failed to count the duplicate as a new usage when the left-hand side is an identifier. That then caused the minifier to believe that the left-hand side was only used once and could attempt to incorrectly inline an initializer into the first usage. This bug has now been fixed:

  // Original code
  function foo() {
    let x
    bar(x ||= {})

... (truncated)

Changelog

Sourced from esbuild's changelog.

Changelog: 2024

This changelog documents all esbuild versions published in the year 2024 (versions 0.19.12 through 0.24.2).

0.24.2

• Fix regression with --define and import.meta (#4010, #4012, #4013)

  The previous change in version 0.24.1 to use a more expression-like parser for define values to allow quoted property names introduced a regression that removed the ability to use --define:import.meta=.... Even though import is normally a keyword that can't be used as an identifier, ES modules special-case the import.meta expression to behave like an identifier anyway. This change fixes the regression.

  This fix was contributed by @​sapphi-red.

0.24.1

• Allow es2024 as a target in tsconfig.json (#4004)

  TypeScript recently added es2024 as a compilation target, so esbuild now supports this in the target field of tsconfig.json files, such as in the following configuration file:

  {
    "compilerOptions": {
      "target": "ES2024"
    }
  }

  As a reminder, the only thing that esbuild uses this field for is determining whether or not to use legacy TypeScript behavior for class fields. You can read more in the documentation.

  This fix was contributed by @​billyjanitsch.

• Allow automatic semicolon insertion after get/set

  This change fixes a grammar bug in the parser that incorrectly treated the following code as a syntax error:

  class Foo {
    get
    *x() {}
    set
    *y() {}
  }

  The above code will be considered valid starting with this release. This change to esbuild follows a similar change to TypeScript which will allow this syntax starting with TypeScript 5.7.

• Allow quoted property names in --define and --pure (#4008)

  The define and pure API options now accept identifier expressions containing quoted property names. Previously all identifiers in the identifier expression had to be bare identifiers. This change now makes --define and --pure consistent with --global-name, which already supported quoted property names. For example, the following is now possible:

Rebuilt dist/index.cjs against the bumped esbuild (0.28.2) — Dependabot doesn't rebuild committed artifacts, and CI's validate-release check confirmed the mismatch before this fix. Verified: 155/155 tests passing, typecheck clean, identical runtime behavior via a live multi-provider check (same version output, same coverage counts, same diff output — only cosmetic minifier formatting differs). This also resolves the 2 vulnerabilities flagged on main (0 vulnerabilities after the bump).
