rollup-plugin-license

Rollup plugin that adds a license banner to the final bundle and generates a file listing all third-party licenses. Current stable version is 3.7.1, released with support for Rollup 4.x peer dependency. Key differentiators: supports multiple banner comment styles (regular, ignored, slash, none), file or string content with Lodash template interpolation, third-party license output with version deduplication, and custom data injection. Widely used for compliance in open-source and enterprise bundles. Ships TypeScript definitions. Maintained actively with regular updates.
