Fix a regression in 0.19.0 regarding paths in tsconfig.json (#3354)
The fix in esbuild version 0.19.0 to process tsconfig.json aliases before the --packages=external setting unintentionally broke an edge case in esbuild's handling of certain tsconfig.json aliases where there are multiple files with the same name in different directories. This release adjusts esbuild's behavior for this edge case so that it passes while still processing aliases before --packages=external. Please read the linked issue for more details.
This release fixes a bug where esbuild's CSS minifier didn't insert a space between the font size and the font family in the font CSS shorthand property in the edge case where the original source code didn't already have a space and the leading string token was shortened to an identifier:
/* Original code */
.foo { font: 16px"Menlo"; }
/* Old output (with --minify) */
.foo{font:16pxMenlo}
/* New output (with --minify) */
.foo{font:16px Menlo}
Fix bundling CSS with asset names containing spaces (#3410)
Assets referenced via CSS url() tokens may cause esbuild to generate invalid output when bundling if the file name contains spaces (e.g. url(image 2.png)). With this release, esbuild will now quote all bundled asset references in url() tokens to avoid this problem. This only affects assets loaded using the file and copy loaders.
Fix invalid CSS url() tokens in @import rules (#3426)
In the future, CSS url() tokens may contain additional stuff after the URL. This is irrelevant today as no CSS specification does this. But esbuild previously had a bug where using these tokens in an @import rule resulted in malformed output. This bug has been fixed.
Fix browser + false + type: module in package.json (#3367)
The browser field in package.json allows you to map a file to false to have it be treated as an empty file when bundling for the browser. However, if package.json contains "type": "module" then all .js files will be considered ESM, not CommonJS. Importing a named import from an empty CommonJS file gives you undefined, but importing a named export from an empty ESM file is a build error. This release changes esbuild's interpretation of these files mapped to false in this situation from ESM to CommonJS to avoid generating build errors for named imports.
Fix a bug in top-level await error reporting (#3400)
Using require() on a file that contains top-level await is not allowed because require() must return synchronously and top-level await makes that impossible. You will get a build error if you try to bundle code that does this with esbuild. This release fixes a bug in esbuild's error reporting code for complex cases of this situation involving multiple levels of imports to get to the module containing the top-level await.
Update to Unicode 15.1.0
The character tables that determine which characters form valid JavaScript identifiers have been updated from Unicode version 15.0.0 to the newly-released Unicode version 15.1.0. I'm not putting an example in the release notes because all of the new characters will likely just show up as little squares since fonts haven't been updated yet. But you can read https://www.unicode.org/versions/Unicode15.1.0/#Summary for more information about the changes.
Fix printing of JavaScript decorators in tricky cases (#3396)
This release fixes some bugs where esbuild's pretty-printing of JavaScript decorators could incorrectly produced code with a syntax error. The problem happened because esbuild sometimes substitutes identifiers for other expressions in the pretty-printer itself, but the decision about whether to wrap the expression or not didn't account for this. Here are some examples:
// Original code
import { constant } from './constants.js'

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={};
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.
