1. How to read this page
Every entry in the tables below is a separate piece of software, owned by its respective copyright holders, distributed under the license shown next to it. None of these licenses give us, or you, ownership of those components — only the rights granted by each license. Where a license requires attribution, this page is the attribution.
The lists are scoped to production dependencies — i.e. code that ships to your device or your browser. They do not include build tools, test frameworks or other development-only dependencies. The full canonical list, including every transitive dependency, is generated at each release with npx license-checker --production --json; you can request the latest snapshot at [email protected].
