Fix non-default JSON import error with export {} from (#3070)
This release fixes a bug where esbuild incorrectly identified statements of the form export { default as x } from "y" assert { type: "json" } as a non-default import. The bug did not affect code of the form import { default as x } from ... (only code that used the export keyword).
Fix a crash with an invalid subpath import (#3067)
Previously esbuild could crash when attempting to generate a friendly error message for an invalid subpath import (i.e. an import starting with #). This happened because esbuild originally only supported the exports field and the code for that error message was not updated when esbuild later added support for the imports field. This crash has been fixed.
Previously esbuild could crash with a stack overflow when lowering CSS nesting rules with a top-level &, such as in the code below. This happened because esbuild's CSS nesting transform didn't handle top-level &, causing esbuild to inline the top-level selector into itself. This release handles top-level & by replacing it with the :scope pseudo-class:
/* Original code */
&,
a {
.b {
color: red;
}
}
/* New output (with --target=chrome90) */
:is(:scope, a) .b {
color: red;
}
Support exports in package.json for extends in tsconfig.json (#3058)
TypeScript 5.0 added the ability to use extends in tsconfig.json to reference a path in a package whose package.json file contains an exports map that points to the correct location. This doesn't automatically work in esbuild because tsconfig.json affects esbuild's path resolution, so esbuild's normal path resolution logic doesn't apply.
This release adds support for doing this by adding some additional code that attempts to resolve the extends path using the exports field. The behavior should be similar enough to esbuild's main path resolution logic to work as expected.
Note that esbuild always treats this extends import as a require() import since that's what TypeScript appears to do. Specifically the require condition will be active and the import condition will be inactive.
Node has a rarely-used feature where you can extend the set of directories that node searches for packages using the NODE_PATH environment variable. While esbuild supports this too, previously a bug prevented esbuild's watch mode from picking up changes to imported files that were contained directly in a NODE_PATH directory. You're supposed to use NODE_PATH for packages, but some people abuse this feature by putting files in that directory instead (e.g. node_modules/some-file.js instead of node_modules/some-pkg/some-file.js). The watch mode bug happens when you do this because esbuild first tries to read some-file.js as a directory and then as a file. Watch mode was incorrectly waiting for some-file.js to become a valid directory. This release fixes this edge case bug by changing watch mode to watch some-file.js as a file when this happens.

Fix CSS nesting transform for triple-nested rules that start with a combinator (#3046)
This release fixes a bug with esbuild where triple-nested CSS rules that start with a combinator were not transformed correctly for older browsers. Here's an example of such a case before and after this bug fix:
