rollup-plugin-oss

Rollup plugin (v0.4.0) that generates a disclosure.json file listing all bundled dependencies with their licenses, and optionally zips source files grouped by package. Works with rollup ≥1.0, vite ≥4.0, and rolldown ≥1.0.0-beta.0. Parses SPDX license expressions, aborts on ambiguous "or" licenses, and uses SPDX license texts. Similar to license-checker-webpack-plugin. Stable release cadence, TypeScript types included.
