Bumps esbuild from 0.18.20 to 0.27.7.

Release notes

Sourced from esbuild's releases.

v0.27.7

  • Fix lowering of define semantics for TypeScript parameter properties (#4421)

    The previous release incorrectly generated class fields for TypeScript parameter properties even when the configured target environment does not support class fields. With this release, the generated class fields will now be correctly lowered in this case:

    // Original code
    class Foo {
      constructor(public x = 1) {}
      y = 2
    }
    // Old output (with --loader=ts --target=es2021)
    class Foo {
    constructor(x = 1) {
    this.x = x;
    __publicField(this, "y", 2);
    }
    x;
    }
    // New output (with --loader=ts --target=es2021)
    class Foo {
    constructor(x = 1) {
    __publicField(this, "x", x);
    __publicField(this, "y", 2);
    }
    }

v0.27.5

  • Fix for an async generator edge case (#4401, #4417)

    Support for transforming async generators into the equivalent state machine was added in version 0.19.0. However, the generated state machine didn't work correctly when polling async generators concurrently, such as in the following code:

    async function* inner() { yield 1; yield 2 }
    async function* outer() { yield* inner() }
    let gen = outer()
    for await (let x of [gen.next(), gen.next()]) console.log(x)

    Previously esbuild's output of the above code behaved incorrectly when async generators were transformed (such as with --supported:async-generator=false). The transformation should be fixed starting with this release.

    This fix was contributed by @​2767mr.

  • Fix a regression when metafile is enabled (#4420, #4418)

    This release fixes a regression introduced by the previous release. When metafile: true was enabled in esbuild's JavaScript API, builds with build errors were incorrectly throwing an error about an empty JSON string instead of an object containing the build errors.

Changelog: 2023

This changelog documents all esbuild versions published in the year 2023 (versions 0.16.13 through 0.19.11).

0.19.11

  • Fix TypeScript-specific class transform edge case (#3559)

    The previous release introduced an optimization that avoided transforming super() in the class constructor for TypeScript code compiled with useDefineForClassFields set to false if all class instance fields have no initializers. The rationale was that in this case, all class instance fields are omitted in the output so no changes to the constructor are needed. However, if all of this is the case and there are #private instance fields with initializers, those private instance field initializers were still being moved into the constructor. This was problematic because they were being inserted before the call to super() (since super() is now no longer transformed in that case). This release introduces an additional optimization that avoids moving the private instance field initializers into the constructor in this edge case, which generates smaller code, matches the TypeScript compiler's output more closely, and avoids this bug:

    // Original code
    class Foo extends Bar {
      #private = 1;
      public: any;
      constructor() {
        super();
      }
    }
    // Old output (with esbuild v0.19.9)
    class Foo extends Bar {
    constructor() {
    super();
    this.#private = 1;
    }
    #private;
    }
    // Old output (with esbuild v0.19.10)
    class Foo extends Bar {
    constructor() {
    this.#private = 1;
    super();
    }
    #private;
    }
    // New output
    class Foo extends Bar {
    #private = 1;
    constructor() {
    super();
    }
    }

  • Minifier: allow reording a primitive past a side-effect (#3568)

    The minifier previously allowed reordering a side-effect past a primitive, but didn't handle the case of reordering a primitive past a side-effect. This additional case is now handled:
