Updates esbuild from 0.25.2 to 0.25.3

Release notes

Sourced from esbuild's releases.

v0.25.3

  • Fix lowered async arrow functions before super() (#4141, #4142)

    This change makes it possible to call an async arrow function in a constructor before calling super() when targeting environments without async support, as long as the function body doesn't reference this. Here's an example (notice the change from this to null):

    // Original code
    class Foo extends Object {
      constructor() {
        (async () => await foo())()
        super()
      }
    }
    // Old output (with --target=es2016)
    class Foo extends Object {
    constructor() {
    (() => __async(this, null, function* () {
    return yield foo();
    }))();
    super();
    }
    }
    // New output (with --target=es2016)
    class Foo extends Object {
    constructor() {
    (() => __async(null, null, function* () {
    return yield foo();
    }))();
    super();
    }
    }

    Some background: Arrow functions with the async keyword are transformed into generator functions for older language targets such as --target=es2016. Since arrow functions capture this, the generated code forwards this into the body of the generator function. However, JavaScript class syntax forbids using this in a constructor before calling super(), and this forwarding was problematic since previously happened even when the function body doesn't use this. Starting with this release, esbuild will now only forward this if it's used within the function body.

    This fix was contributed by @​magic-akari.

  • Fix memory leak with --watch=true (#4131, #4132)

    This release fixes a memory leak with esbuild when --watch=true is used instead of --watch. Previously using --watch=true caused esbuild to continue to use more and more memory for every rebuild, but --watch=true should now behave like --watch and not leak memory.

    This bug happened because esbuild disables the garbage collector when it's not run as a long-lived process for extra speed, but esbuild's checks for which arguments cause esbuild to be a long-lived process weren't updated for the new --watch=true style of boolean command-line flags. This has been an issue since this boolean flag syntax was added in version 0.14.24 in 2022. These checks are unfortunately separate from the regular argument parser because of how esbuild's internals are organized (the command-line interface is exposed as a separate Go API so you can build your own custom esbuild CLI).

    This fix was contributed by @​mxschmitt.

  • More concise output for repeated legal comments (#4139)

    Some libraries have many files and also use the same legal comment text in all files. Previously esbuild would copy each legal comment to the output file. Starting with this release, legal comments duplicated across separate files will now be grouped in the output file by unique comment content.
