Best practices for improving website performance with React?
Hi everyone,
I’m currently working on optimizing a web application built with React, and I’ve run into some performance challenges. I’ve already implemented some best practices like code splitting and lazy loading for components, but there are still areas where the app feels slow, particularly with large datasets.
I’m looking for suggestions on the following:
Efficient state management techniques that can reduce unnecessary re-renders in large-scale React applications.
Optimizing bundle sizes further, especially with libraries like React Router and Redux.
Any specific tools or libraries that help monitor performance during development and production stages.
Best practices for handling image optimization and caching in React apps.
If anyone has faced similar issues or has experience with these optimizations, I’d love to hear your insights!
Thanks in advance for your help!

To improve React website performance, use lazy loading with React.lazy() and Suspense to load components on demand. Implement code splitting using dynamic import() to reduce bundle size. Memoize expensive calculations with React.memo and useMemo to avoid unnecessary re-renders. Use useCallback to optimize function references in props. Implement virtualization with libraries like react-window for large lists. Minimize component re-renders by using the key attribute efficiently. Leverage React’s Profiler to detect performance bottlenecks. Optimize images and serve them in modern formats (like WebP). Finally, enable Gzip or Brotli compression and cache static assets for faster load times.
