Bumps github.com/evanw/esbuild from 0.12.10 to 0.17.11.

Release notes

Sourced from github.com/evanw/esbuild's releases.

v0.17.11

  • Fix the alias feature to always prefer the longest match (#2963)

    It's possible to configure conflicting aliases such as --alias:a=b and --alias:a/c=d, which is ambiguous for the import path a/c/x (since it could map to either b/c/x or d/x). Previously esbuild would pick the first matching alias, which would non-deterministically pick between one of the possible matches. This release fixes esbuild to always deterministically pick the longest possible match.

  • Minify calls to some global primitive constructors (#2962)

    With this release, esbuild's minifier now replaces calls to Boolean/Number/String/BigInt with equivalent shorter code when relevant:

    // Original code
console.log(
  Boolean(a ? (b | c) !== 0 : (c & d) !== 0),
  Number(e ? '1' : '2'),
  String(e ? '1' : '2'),
  BigInt(e ? 1n : 2n),
)

    // Old output (with --minify)
console.log(Boolean(a?(b|c)!==0:(c&d)!==0),Number(e?"1":"2"),String(e?"1":"2"),BigInt(e?1n:2n));
    

    // New output (with --minify)
console.log(!!(a?b|c:c&d),+(e?"1":"2"),e?"1":"2",e?1n:2n);

  • Adjust some feature compatibility tables for node (#2940)

    This release makes the following adjustments to esbuild's internal feature compatibility tables for node, which tell esbuild which versions of node are known to support all aspects of that feature:

    • class-private-brand-checks: node v16.9+ => node v16.4+ (a decrease)
    • hashbang: node v12.0+ => node v12.5+ (an increase)
    • optional-chain: node v16.9+ => node v16.1+ (a decrease)
    • template-literal: node v4+ => node v10+ (an increase)

    Each of these adjustments was identified by comparing against data from the node-compat-table package and was manually verified using old node executables downloaded from https://nodejs.org/download/release/.

v0.17.10

  • Update esbuild's handling of CSS nesting to match the latest specification changes (#1945)

    The syntax for the upcoming CSS nesting feature has recently changed. The @nest prefix that was previously required in some cases is now gone, and nested rules no longer have to start with & (as long as they don't start with an identifier or function token).

    This release updates esbuild's pass-through handling of CSS nesting syntax to match the latest specification changes. So you can now use esbuild to bundle CSS containing nested rules and try them out in a browser that supports CSS nesting (which includes nightly builds of both Chrome and Safari).

    However, I'm not implementing lowering of nested CSS to non-nested CSS for older browsers yet. While the syntax has been decided, the semantics are still in flux. In particular, there is still some debate about changing the fundamental way that CSS nesting works. For example, you might think that the following CSS is equivalent to a .outer .inner button { ... } rule:

    .inner button {
  .outer & {
    color: red;
  }

Changelog: 2021

This changelog documents all esbuild versions published in the year 2021 (versions 0.8.29 through 0.14.10).

0.14.10

  • 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.
