Production-ready patterns for optimizing bundle size and build performance in Vite + React applications. These patterns leverage Vite's architecture (native ESM in dev, Rollup in production) to deliver smaller, faster bundles.

When to Use

Reference these patterns when:

• Setting up a new Vite + React project for production
• Analyzing bundle size with npx vite-bundle-visualizer
• Build times are slow or bundles are unexpectedly large
• Migrating from webpack/CRA to Vite
• Optimizing Core Web Vitals (LCP, FID/INP, CLS)
