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.
Preferences
- Use TypeScript: prefer
vite.config.ts - Always use ESM, avoid CommonJS
