Building Scalable React Applications
M
Marcus Lee
Learn the best practices for building large-scale React applications that perform well.
React is powerful, but scaling requires discipline. Here are patterns we have refined over years of development.
Architecture:
1. Component organization by feature
2. Custom hooks for logic reuse
3. Context for global state
4. Lazy loading for performance
Performance Tips:
1. Memoize expensive calculations
2. Virtualize long lists
3. Optimize bundle size
4. Use proper key management
State Management:
- Local state for UI
- Context for global themes
- Redux/Zustand for complex state
- React Query for server state
