Vite build tool configuration, plugin API, SSR, and Vite 8 Rolldown migration. Use when working with Vite projects, vite.config.ts, Vite plugins, or building libraries/SSR apps with Vite.
Based on Vite v8.3.1 (Rolldown-powered), generated at 2026-09-25. Vite 8 uses the Rolldown bundler and the Oxc transformer instead of esbuild + Rollup.
Vite is a next-generation frontend build tool with fast dev server (native ESM + HMR) and optimized production builds.
