Original: Rust Ate the JavaScript Toolchain. Then Cloudflare Bought It
Short summary
Vite 8 ships Rolldown, a Rust-based bundler replacing esbuild and Rollup, delivering 10–30x faster builds while maintaining API compatibility. Cloudflare's acquisition of VoidZero, the company behind Vite and Rolldown, concentrates significant influence over foundational web tooling, though the projects remain MIT-licensed and vendor-neutral. Upgrade safely in a two-step process: test rolldown-vite on Vite 7 first, then take the major upgrade to Vite 8.
- •Vite 8 replaces dual bundler (esbuild + Rollup) with Rust-based Rolldown for 10–30x faster builds
- •Cloudflare's acquisition of VoidZero concentrates influence over core web tooling despite open-source pledges
- •Two-step migration path minimizes risk: test rolldown-vite on Vite 7, then upgrade to Vite 8
