Use when working with Vite projects, vite.config.ts, Vite plugins, or building libraries/SSR apps with Vite.metadata:   author: Anthony Fu  version: "2026.11.5"  source: Generated from https://github.com/vitejs/vite, scripts at https://github.com/antfu/skills

Vite

Based on Vite v8.3.5 (Rolldown-powered), generated at 2026-11-05. 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
