The term, in context

AI-assisted draft · approved dataset

Rolldown is a JavaScript and TypeScript bundler written in Rust that exposes a plugin interface deliberately compatible with Rollup's API, letting most existing Rollup and Vite plugins run with little or no change. It combines the fast dependency pre-bundling role and the full production-bundling role that a typical build toolchain previously split across two separate tools into a single engine.
