Vite 8 (Rolldown-powered) build tool — configuration, plugin API, SSR, and
Rolldown migration. Use when working with Vite projects, vite.config.ts,
HMR, Vite plugins, library mode, SSR builds, or migrating from Vite 5/6 to
Vite 8. Trigger when the user mentions Vite, vite.config, vitest (config
side), HMR, Rolldown, Rollup plugin, or asks to configure, debug, or
optimize a Vite-based project (Vue, React, Svelte, Nuxt, SvelteKit).

Vite
Based on Vite 8 beta (Rolldown-powered). Vite 8 uses Rolldown bundler and Oxc transformer.
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
