How to optimize React performance in large applications | IT-Community Forum | IT-Community - The Forum for IT Professionals
I'm working on a large React application and experiencing performance issues. What are the best practices for optimizing React performance in 2025? Specifically looking for tips on:
1. State management optimization
2. Reducing unnecessary re-renders
3. Code splitting strategies
4. Server components vs client components
5. Caching strategies
Has anyone implemented any of these techniques successfully?
