Vite 8 has been released, featuring a new unified bundler called Rolldown, which replaces the previous dual-bundler approach with esbuild and Rollup. This change brings significant performance improvements, with build times reduced by up to 10-30x. The new version also includes other features such as integrated devtools, TypeScript path alias resolution, and WebAssembly support. Vite 8 requires Node.js 20.19+ or 22.12+ and has a larger install size due to the inclusion of Rolldown and lightningcss.
