Vite

Covers Vite's build tool essentials from dev server setup to production builds, with specific focus on the new Vite 8 beta that swaps out the bundler for Rolldown and transformer for Oxc. Walks through vite.config.ts configuration, plugin API hooks, SSR middleware patterns, and the Environment API for multi-environment setups. Includes migration guidance for the Rolldown transition, which changes how some plugins work and requires config updates. Solid reference when you're setting up Vite projects, writing custom plugins, or need to understand what breaks when upgrading to the Rolldown-powered version.

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
