Bump esbuild from 0.8.57 to 0.16.17 #190

Closed dependabot[bot] closed 1 year ago

Bumps esbuild from 0.8.57 to 0.16.17.

Release notes

Sourced from esbuild's releases.

v0.16.17

  • Fix additional comment-related regressions (#2814)

    This release fixes more edge cases where the new comment preservation behavior that was added in 0.16.14 could introduce syntax errors. Specifically:

    x = () => (/* comment */ {})
for ((/* comment */ let).x of y) ;
function *f() { yield (/* comment */class {}) }

    These cases caused esbuild to generate code with a syntax error in version 0.16.14 or above. These bugs have now been fixed.

v0.16.16

  • Fix a regression caused by comment preservation (#2805)

    The new comment preservation behavior that was added in 0.16.14 introduced a regression where comments in certain locations could cause esbuild to omit certain necessary parentheses in the output. The outermost parentheses were incorrectly removed for the following syntax forms, which then introduced syntax errors:

    (/* comment */ { x: 0 }).x;
(/* comment */ function () { })();
(/* comment */ class { }).prototype;

    This regression has been fixed.

v0.16.15

  • Add format to input files in the JSON metafile data

    When --metafile is enabled, input files may now have an additional format field that indicates the export format used by this file. When present, the value will either be cjs for CommonJS-style exports or esm for ESM-style exports. This can be useful in bundle analysis.

    For example, esbuild's new Bundle Size Analyzer now uses this information to visualize whether ESM or CommonJS was used for each directory and file of source code (click on the CJS/ESM bar at the top).

    This information is helpful when trying to reduce the size of your bundle. Using the ESM variant of a dependency instead of the CommonJS variant always results in a faster and smaller bundle because it omits CommonJS wrappers, and also may result in better tree-shaking as it allows esbuild to perform tree-shaking at the statement level instead of the module level.

  • Fix a bundling edge case with dynamic import (#2793)

    This release fixes a bug where esbuild's bundler could produce incorrect output. The problematic edge case involves the entry point importing itself using a dynamic import() expression in an imported file, like this:

    // src/a.js
export const A = 42;

    // src/b.js
export const B = async () => (await import(".")).A
    

    // src/index.js
export * from "./a"
export * from "./b"

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.
