# 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
