• Add support for with { type: 'text' } imports (#​4435)

  The import text proposal has reached stage 3 in the TC39 process, which means that it's recommended for implementation. It has also already been implemented by Deno and Bun. So with this release, esbuild also adds support for it. This behaves exactly the same as esbuild's existing text loader. Here's an example:

  import string from './example.txt' with { type: 'text' }
  console.log(string)

• Add integrity checks to fallback download path (#​4343)

  Installing esbuild via npm is somewhat complicated with several different edge cases (see esbuild's documentation for details). If the regular installation of esbuild's platform-specific package fails, esbuild's install script attempts to download the platform-specific package itself (first with the npm command, and then with a HTTP request to registry.npmjs.org as a last resort).

  This last resort path previously didn't have any integrity checks. With this release, esbuild will now verify that the hash of the downloaded binary matches the expected hash for the current release. This means the hashes for all of esbuild's platform-specific binary packages will now be embedded in the top-level esbuild package. Hopefully this should work without any problems. But just in case, this change is being done as a breaking change release.

• Update the Go compiler from 1.25.7 to 1.26.1

  This upgrade should not affect anything. However, there have been some significant internal changes to the Go compiler, so esbuild could potentially behave differently in certain edge cases:

  • It now uses the new garbage collector that comes with Go 1.26.
  • The Go compiler is now more aggressive with allocating memory on the stack.
  • The executable format that the Go linker uses has undergone several changes.
  • The WebAssembly build now unconditionally makes use of the sign extension and non-trapping floating-point to integer conversion instructions.

  You can read the Go 1.26 release notes for more information.

• Speed up source map encoding paring in case of the error.

v1.99.0

Compare Source

• Add support for parent selectors (&) at the root of the document. These are
  emitted as-is in the CSS output, where they're interpreted as the scoping
  root.

• User-defined functions named calc or clamp are no longer forbidden. If
  such a function exists without a namespace in the current module, it will be
  used instead of the built-in calc() or clamp() function.

• User-defined functions whose names begin with - and end with -expression,
  -url, -and, -or, or -not are no longer forbidden. These were
  originally intended to match vendor prefixes, but in practice no vendor
  prefixes for these functions ever existed in real browsers.

• User-defined functions named EXPRESSION, URL, and ELEMENT, those that
  begin with - and end with -ELEMENT, as well as the same names with some
  lowercase letters are now deprecated, These are names conflict with plain CSS
  functions that have special syntax.

  See the Sass website for details.

• In a future release, calls to functions whose names begin with - and end
  with -expression and -url will no longer have special parsing. For now,
  these calls are deprecated if their behavior will change in the future.

  See the Sass website for details.

• Calls to functions whose names begin with - and end with -progid:... are
  deprecated.

  See the Sass website for details.
