Bumps esbuild from 0.15.5 to 0.18.11.

Release notes

Sourced from esbuild's releases.

v0.18.11

  • Fix a TypeScript code generation edge case (#3199)

    This release fixes a regression in version 0.18.4 where using a TypeScript namespace that exports a class declaration combined with --keep-names and a --target of es2021 or earlier could cause esbuild to export the class from the namespace using an incorrect name (notice the assignment to X2._Y vs. X2.Y):

    // Original code

    // Old output (with --keep-names --target=es2021)
var X;
((X2) => {
const _Y = class _Y {
};
__name(_Y, "Y");
let Y = _Y;
X2._Y = _Y;
})(X || (X = {}));
    

    // New output (with --keep-names --target=es2021)
var X;
((X2) => {
const _Y = class _Y {
};
__name(_Y, "Y");
let Y = _Y;
X2.Y = _Y;
})(X || (X = {}));

v0.18.10

  • Fix a tree-shaking bug that removed side effects (#3195)

    This fixes a regression in version 0.18.4 where combining --minify-syntax with --keep-names could cause expressions with side effects after a function declaration to be considered side-effect free for tree shaking purposes. The reason was because --keep-names generates an expression statement containing a call to a helper function after the function declaration with a special flag that makes the function call able to be tree shaken, and then --minify-syntax could potentially merge that expression statement with following expressions without clearing the flag. This release fixes the bug by clearing the flag when merging expression statements together.

  • Fix an incorrect warning about CSS nesting (#3197)

    A warning is currently generated when transforming nested CSS to a browser that doesn't support :is() because transformed nested CSS may need to use that feature to represent nesting. This was previously always triggered when an at-rule was encountered in a declaration context. Typically the only case you would encounter this is when using CSS nesting within a selector rule. However, there is a case where that's not true: when using a margin at-rule such as @top-left within @page. This release avoids incorrectly generating a warning in this case by checking that the at-rule is within a selector rule before generating a warning.

v0.18.9

  • Fix await using declarations inside async generator functions

    I forgot about the new await using declarations when implementing lowering for async generator functions in the previous release. This change fixes the transformation of await using declarations when they are inside lowered async generator functions:

    // Original code
async function* foo() {
  await using x = await y
}

    // Old output (with --supported:async-generator=false)

Changelog: 2022

This changelog documents all esbuild versions published in the year 2022 (versions 0.14.11 through 0.16.12).

0.16.12

  • Loader defaults to js for extensionless files (#2776)

    Certain packages contain files without an extension. For example, the yargs package contains the file yargs/yargs which has no extension. Node, Webpack, and Parcel can all understand code that imports yargs/yargs because they assume that the file is JavaScript. However, esbuild was previously unable to understand this code because it relies on the file extension to tell it how to interpret the file. With this release, esbuild will now assume files without an extension are JavaScript files. This can be customized by setting the loader for "" (the empty string, representing files without an extension) to another loader. For example, if you want files without an extension to be treated as CSS instead, you can do that like this:

    • CLI:

      esbuild --bundle --loader:=css

    • JS:

      esbuild.build({
  bundle: true,
  loader: { '': 'css' },
})

    • Go:

      api.Build(api.BuildOptions{
  Bundle: true,
  Loader: map[string]api.Loader{"": api.LoaderCSS},
})

    In addition, the "type" field in package.json files now only applies to files with an explicit .js, .jsx, .ts, or .tsx extension. Previously it was incorrectly applied by esbuild to all files that had an extension other than .mjs, .mts, .cjs, or .cts including extensionless files. So for example an extensionless file in a "type": "module" package is now treated as CommonJS instead of ESM.

0.16.11

  • Avoid a syntax error in the presence of direct eval (#2761)

    The behavior of nested function declarations in JavaScript depends on whether the code is run in strict mode or not. It would be problematic if esbuild preserved nested function declarations in its output because then the behavior would depend on whether the output was run in strict mode or not instead of respecting the strict mode behavior of the original source code. To avoid this, esbuild transforms nested function declarations to preserve the intended behavior of the original source code regardless of whether the output is run in strict mode or not:

    // Original code
if (true) {
  function foo() {}
  console.log(!!foo)
  foo = null
  console.log(!!foo)
}
