React Best Practices for 2024

React continues to evolve. This guide covers the patterns and techniques you should be using in 2024.

Modern React Patterns

Server Components

• Reduced bundle size
• Direct database access
• Improved initial load time

React Server Components blur the line between server and client, giving you the best of both worlds.

State Management

Component Design

1. Use composition over configuration
2. Keep components focused (single responsibility)
3. Extract logic into custom hooks

Performance Optimization

// Use useMemo for expensive calculations
const expensiveValue = useMemo(() => {
  return items.filter(item => item.active)
    .reduce((sum, item) => sum + item.price, 0);
}, [items]);

• React.memo for expensive renders
• useMemo for calculations
• useCallback for stable references

Conclusion

Modern React development is about leveraging the right tools and patterns. Follow these best practices for performant, maintainable applications.
