Bump esbuild from 0.24.0 to 0.25.2

[dependabot]

Bumps esbuild from 0.24.0 to 0.25.2.

Release notes

Sourced from esbuild's releases.

v0.25.2

• Support flags in regular expressions for the API (#4121)

  The JavaScript plugin API for esbuild takes JavaScript regular expression objects for the filter option. Internally these are translated into Go regular expressions. However, this translation previously ignored the flags property of the regular expression. With this release, esbuild will now translate JavaScript regular expression flags into Go regular expression flags. Specifically the JavaScript regular expression /\.[jt]sx?$/i is turned into the Go regular expression `(?i)\.[jt]sx?$` internally inside of esbuild's API. This should make it possible to use JavaScript regular expressions with the i flag. Note that JavaScript and Go don't support all of the same regular expression features, so this mapping is only approximate.

• Fix node-specific annotations for string literal export names (#4100)

  When node instantiates a CommonJS module, it scans the AST to look for names to expose via ESM named exports. This is a heuristic that looks for certain patterns such as exports.NAME = ... or module.exports = { ... }. This behavior is used by esbuild to "annotate" CommonJS code that was converted from ESM with the original ESM export names. For example, when converting the file export let foo, bar from ESM to CommonJS, esbuild appends this to the end of the file:

  // Annotate the CommonJS export names for ESM import in node:
  0 && (module.exports = {
    bar,
    foo
  });

  However, this feature previously didn't work correctly for export names that are not valid identifiers, which can be constructed using string literal export names. The generated code contained a syntax error. That problem is fixed in this release:

  // Original code
  let foo
  export { foo as "foo!" }
  // Old output (with --format=cjs --platform=node)
  ...
  0 && (module.exports = {
  "foo!"
  });
  // New output (with --format=cjs --platform=node)
  ...
  0 && (module.exports = {
  "foo!": null
  });

• Basic support for index source maps (#3439, #4109)

  The source map specification has an optional mode called index source maps that makes it easier for tools to create an aggregate JavaScript file by concatenating many smaller JavaScript files with source maps, and then generate an aggregate source map by simply providing the original source maps along with some offset information. My understanding is that this is rarely used in practice. I'm only aware of two uses of it in the wild: ClojureScript and Turbopack.

  This release provides basic support for indexed source maps. However, the implementation has not been tested on a real app (just on very simple test input). If you are using index source maps in a real app, please try this out and report back if anything isn't working for you.

  Note that this is also not a complete implementation. For example, index source maps technically allows nesting source maps to an arbitrary depth, while esbuild's implementation in this release only supports a single level of nesting. It's unclear whether supporting more than one level of nesting is important or not given the lack of available test cases.

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:
