Bumps esbuild from 0.14.1 to 0.14.10.

Release notes

Sourced from esbuild's releases.

v0.14.10

  • Enable tree shaking of classes with lowered static fields (#175)

    If the configured target environment doesn't support static class fields, they are converted into a call to esbuild's __publicField function instead. However, esbuild's tree-shaking pass treated this call as a side effect, which meant that all classes with static fields were ineligible for tree shaking. This release fixes the problem by explicitly ignoring calls to the __publicField function during tree shaking side-effect determination. Tree shaking is now enabled for these classes:

    // Original code
    class Foo { static foo = 'foo' }
    class Bar { static bar = 'bar' }
    new Bar()
    // Old output (with --tree-shaking=true --target=es6)
    class Foo {
    }
    __publicField(Foo, "foo", "foo");
    class Bar {
    }
    __publicField(Bar, "bar", "bar");
    new Bar();
    // New output (with --tree-shaking=true --target=es6)
    class Bar {
    }
    __publicField(Bar, "bar", "bar");
    new Bar();

  • Treat --define:foo=undefined as an undefined literal instead of an identifier (#1407)

    References to the global variable undefined are automatically replaced with the literal value for undefined, which appears as void 0 when printed. This allows for additional optimizations such as collapsing undefined ?? bar into just bar. However, this substitution was not done for values specified via --define:. As a result, esbuild could potentially miss out on certain optimizations in these cases. With this release, it's now possible to use --define: to substitute something with an undefined literal:

    // Original code
    let win = typeof window !== 'undefined' ? window : {}
    // Old output (with --define:window=undefined --minify)
    let win=typeof undefined!="undefined"?undefined:{};
    // New output (with --define:window=undefined --minify)
    let win={};

  • Add the --drop:debugger flag (#1809)

    Passing this flag causes all debugger; statements to be removed from the output. This is similar to the drop_debugger: true flag available in the popular UglifyJS and Terser JavaScript minifiers.

  • Add the --drop:console flag (#28)

    Passing this flag causes all console.xyz() API calls to be removed from the output. This is similar to the drop_console: true flag available in the popular UglifyJS and Terser JavaScript minifiers.
