Yarn Plug'n'Play is one of 10 APIs that [Yarn](https://apis.io/providers/yarn-pkg/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include Plug'n'Play, PnP, Module Resolution, and JavaScript. The published artifact set on APIs.io includes API documentation.

Plug'n'Play (PnP) is Yarn's alternative to the traditional node_modules folder. Yarn generates a single `.pnp.cjs` file containing the exact dependency tree which Node.js consults at runtime via a require hook. PnP enables faster installs, deterministic module resolution, and strict boundaries between declared and undeclared dependencies. A Rust implementation (pnp-rs) is available for non-Node runtimes.
