10 React Performance Optimization Tips
Performance is crucial for user experience. Here are some tips to optimize your React apps.
1. Use React.memo for Pure Components
const MyComponent = React.memo(({ data }) => { return <div>{data.name}</div>;});2. Implement useMemo and useCallback
Use these hooks to prevent unnecessary re-computations and re-renders.
3. Virtualize Long Lists
Use libraries like react-window for rendering large lists efficiently.
4. Code Splitting with React.lazy
const LazyComponent = React.lazy(() => import('./HeavyComponent'));5. Optimize Images
Use next/image or similar tools for automatic image optimization.
These are just a few tips. Performance optimization is an ongoing process!
