build(deps-dev): bump esbuild from 0.14.49 to 0.25.8

[dependabot]

Bumps esbuild from 0.14.49 to 0.25.8.

Release notes

Sourced from esbuild's releases.

v0.25.8

• Fix another TypeScript parsing edge case (#4248)

  This fixes a regression with a change in the previous release that tries to more accurately parse TypeScript arrow functions inside the ?: operator. The regression specifically involves parsing an arrow function containing a #private identifier inside the middle of a ?: ternary operator inside a class body. This was fixed by propagating private identifier state into the parser clone used to speculatively parse the arrow function body. Here is an example of some affected code:

  class CachedDict {
    #has = (a: string) => dict.has(a);
    has = window
      ? (word: string): boolean => this.#has(word)
      : this.#has;
  }

• Fix a regression with the parsing of source phase imports

  The change in the previous release to parse source phase imports failed to properly handle the following cases:

  import source from 'bar'
  import source from from 'bar'
  import source type foo from 'bar'

  Parsing for these cases should now be fixed. The first case was incorrectly treated as a syntax error because esbuild was expecting the second case. And the last case was previously allowed but is now forbidden. TypeScript hasn't added this feature yet so it remains to be seen whether the last case will be allowed, but it's safer to disallow it for now. At least Babel doesn't allow the last case when parsing TypeScript, and Babel was involved with the source phase import specification.

v0.25.7

• Parse and print JavaScript imports with an explicit phase (#4238)

  This release adds basic syntax support for the defer and source import phases in JavaScript:

  • defer

    This is a stage 3 proposal for an upcoming JavaScript feature that will provide one way to eagerly load but lazily initialize imported modules. The imported module is automatically initialized on first use. Support for this syntax will also be part of the upcoming release of TypeScript 5.9. The syntax looks like this:

    import defer * as foo from "<specifier>";
    const bar = await import.defer("<specifier>");

    Note that this feature deliberately cannot be used with the syntax import defer foo from "<specifier>" or import defer { foo } from "<specifier>".

  • source

    This is a stage 3 proposal for an upcoming JavaScript feature that will provide another way to eagerly load but lazily initialize imported modules. The imported module is returned in an uninitialized state. Support for this syntax may or may not be a part of TypeScript 5.9 (see this issue for details). The syntax looks like this:

    import source foo from "<specifier>";
    const bar = await import.source("<specifier>");

Changelog: 2022

This changelog documents all esbuild versions published in the year 2022 (versions 0.14.11 through 0.16.12).

0.16.12

• Loader defaults to js for extensionless files (#2776)

  Certain packages contain files without an extension. For example, the yargs package contains the file yargs/yargs which has no extension. Node, Webpack, and Parcel can all understand code that imports yargs/yargs because they assume that the file is JavaScript. However, esbuild was previously unable to understand this code because it relies on the file extension to tell it how to interpret the file. With this release, esbuild will now assume files without an extension are JavaScript files. This can be customized by setting the loader for "" (the empty string, representing files without an extension) to another loader. For example, if you want files without an extension to be treated as CSS instead, you can do that like this:

  • CLI:

    esbuild --bundle --loader:=css
    

  • JS:

    esbuild.build({
      bundle: true,
      loader: { '': 'css' },
    })

  • Go:

    api.Build(api.BuildOptions{
      Bundle: true,
      Loader: map[string]api.Loader{"": api.LoaderCSS},
    })

  In addition, the "type" field in package.json files now only applies to files with an explicit .js, .jsx, .ts, or .tsx extension. Previously it was incorrectly applied by esbuild to all files that had an extension other than .mjs, .mts, .cjs, or .cts including extensionless files. So for example an extensionless file in a "type": "module" package is now treated as CommonJS instead of ESM.

0.16.11

• Avoid a syntax error in the presence of direct eval (#2761)

  The behavior of nested function declarations in JavaScript depends on whether the code is run in strict mode or not. It would be problematic if esbuild preserved nested function declarations in its output because then the behavior would depend on whether the output was run in strict mode or not instead of respecting the strict mode behavior of the original source code. To avoid this, esbuild transforms nested function declarations to preserve the intended behavior of the original source code regardless of whether the output is run in strict mode or not:

  // Original code
  if (true) {
    function foo() {}
    console.log(!!foo)
    foo = null
    console.log(!!foo)
  }
