Important Changes

New Features

• Support for OutputOptions.file has been added.
• Treeshaking is now available for dynamic import(...).
• Legal comments can be preserved using OutputOptions#comments: 'preserve-legal'.
• A new build API has been introduced for more user-friendly programmatic usage.

// Instead of
(await (await rolldown(options)).write(options.output))

// Use `build`
await build(options)

UX Improvements

• The platform is automatically set to node when the output format is cjs, if not specified.
• Automatic polyfill for require is provided when bundling code that mixes ESM and CJS to format: 'esm' with platform: 'node'.
• Automatic polyfill for import.meta.url is provided when bundling ESM code to format: 'cjs' with platform: 'node'.

Correctness

• To improve interoperability between ESM and CJS, Rolldown passes all tests listed in bundler-esm-cjs-tests.
