# Vite 7 Build tooling and dev server for React projects. Vite 7 (June 2025) is ESM-only, requires Node.js 20.19+ / 22.12+, and defaults browser target to `baseline-widely-available`. The user's stack uses `rolldown-vite` (Rust-based drop-in replacement), `@vitejs/plugin-react`, `@tailwindcss/vite`, `@tanstack/router-plugin`, `@cloudflare/vite-plugin`, and `@tanstack/react-start`. ## Critical Rules ### Plugin Order Matters TanStack Start or TanStack Router plugin MUST come before `@vitejs/plugin-react`: ```ts plugins: [ tanstackStart(), // or tanstackRouter() for SPA tailwindcss(), react(), // ALWAYS last among framework plugins ] ``` Wrong order causes route generation failures and HMR breakage. ### Vite 7 is ESM-Only Vite 7 distributes as ESM only. Your `vite.config.ts` must use `import`/`export` syntax. CJS `require()` is not supported in config files. Node.js 20.19+ supports `require(esm)` natively, so Vite can still be required by CJS consumers. ### No `tailwind.config.js` Tailwind CSS v4 uses CSS-first configuration. Never create `tailwind.config.js`/`tailwind.config.ts`. Use `@tailwindcss/vite` plugin and configure in CSS via `@theme`, `@utility`, `@plugin`. ### Environment Variables Need VITE_ Prefix Only variables prefixed with `VITE_` are exposed to client code via `import.meta.env`. Server-only secrets must NOT use this prefix. For type safety, augment `ImportMetaEnv` in `vite-env.d.ts`. ### splitVendorChunkPlugin Is Removed Re
