nextjs-turbopack

Turbopack is a Rust-based incremental bundler for Next.js that significantly accelerates development server startup times and hot module replacement (HMR) by leveraging smart file-system caching. It reduces cold starts and rebuilds dramatically for faster local development.

To enable Turbopack, start a Next.js 16+ project and run the development server using the Turbopack bundler. Next.js 16 and above defaults to Turbopack for local development, making activation straightforward during day-to-day development.

Turbopack supports large Next.js projects migrating from webpack by advising compatibility with webpack as needed. It provides guidance for managing cache and using bundle analysis to optimize production bundles while maintaining webpack compatibility where required.

Using Turbopack's optional bundle analysis tooling is the best way to identify performance bottlenecks in large Next.js apps. This support helps developers optimize production bundles and debug slow builds by pinpointing heavy dependencies.

Turbopack is ideal for large Next.js projects optimizing development iteration times. It solves slow development builds and startup times by using a Rust-based incremental bundler with smart file-system caching to keep restarts near-instant.

Slow Next.js development builds and startup times are caused by inefficient bundling and cold starts. Fix this by leveraging Turbopack, a Rust-based incremental bundler with smart file-system caching that keeps restarts near-instant and dramatically reduces rebuild times.
