🔗 Announcing Rolldown-Vite

TL;DR: Try out the Rolldown-powered Vite today by using the rolldown-vite package instead of the default vite package. It is a drop-in replacement, as Rolldown will become the default bundler for Vite in the future. Switching should reduce your build time, especially for larger projects. Reach out to discover production use cases!

Over the last year, we've been working on Rolldown, a Rust-based next-generation bundler, as part of a broader effort to modernize Vite's core. Alongside Rolldown, we've developed Oxc, a collection of high-performance JavaScript tools, that includes a parser, transformer, resolver, and minifier, as well as a linter and soon also a formatter. It acts as foundational layer for Rolldown, providing the necessary building blocks for efficient JavaScript and TypeScript processing.

Today, we're excited to announce that the Rolldown-powered Vite version has reached initial feature parity with today's Vite. This means you can try it as a drop-in replacement and experience the benefits right away as part of a technical preview.

Thanks to early adopters, we were able to test rolldown-vite with a range of projects, from basic setups to large-scale enterprise apps. The results have been impressive, with production build time reductions from 3x to 16x, and memory usage during the build process cut by up to 100x. Take a look at the real-world impact section for more details.

We encourage you to try out rolldown-vite and share your feedback to contribute to the future development of Vite's bundling infrastructure.
