Million.js Has Free React Optimization — Here's How to Make React 70% Faster Without Changing Your Code

React's virtual DOM is slow for large lists. Million.js replaces it with a faster one — without changing your components. What is Million.js? Million.js is a drop-in virtual DOM replacement for React that makes rendering up to 70% faster. It works by using a compiler to optimize your components. Quick Start bun add million bun add -d @million/lint // next.config.js (Next.js) import million from ' million/compiler ' ; export default million . next ({ auto : true }); // vite.config.ts (Vite) import million from ' million/compiler ' ; export default defineConfig ({ plugins : [ million . vite ({ auto : true }), react ()], }); That is it. With auto: true , Million.js automatically optimizes your components. How It Works React's virtual DOM diffs the entire tree on every render. Million.js uses static analysis to skip the diff for parts that cannot change. React: Render → Full vDOM diff → DOM update Million.js: Render → Skip static parts → Targeted DOM update Manual Optimization with block()
