Turbopack

Turbopack is an incremental bundler optimized for JavaScript and TypeScript, written in Rust by the creators of webpack and Next.js at Vercel.

The secret to Turbopack's performance is twofold: highly optimized machine code and a low-level incremental computation engine that enables caching down to the level of individual functions. Once Turbopack performs a task it never does it again.

Our team has taken the lessons from 10 years of webpack, combined with the innovations in incremental computation from Turborepo and Google's Bazel, and created an architecture ready to support the coming decades of computing.
