Vite 8 Complete Guide: Rolldown, Oxc, and 10x Faster Builds (2026)

Short summary

Vite 8 ships with Rolldown (Rust-based bundler replacing Rollup) and Oxc (Rust-based parser/transformer replacing esbuild), cutting production build times 10–30x. The guide covers setup, migration from Vite 6/7, Full Bundle Mode for development, native TypeScript path resolution, and the removal of Babel dependencies. Real-world results include Linear's build dropping from 46s to 6s and GitLab shrinking by 7x.

• •Vite 8 replaces esbuild+Rollup with Rolldown+Oxc (both Rust-based), achieving 10–30x faster builds
• •Full Bundle Mode bundles during development too, giving 3x faster dev startup and identical dev/prod behavior
• •Migration is mostly zero-config; existing rollupOptions work via compatibility layer, Babel is removed in favor of Oxc
