React Best Practices for 2025

React continues to evolve with new patterns and features. Here are the best practices every React developer should follow in 2025.

Server Components

Use React Server Components by default. They reduce the JavaScript bundle sent to the client and allow direct database access from components.

State Management

Keep state as local as possible. Use React's built-in useState and useReducer for component state. Only reach for external libraries when you need to share state across distant components.

Performance

• Use React.memo sparingly and only when you've measured a performance issue
• Leverage the new React Compiler for automatic optimizations
• Use Suspense boundaries for code splitting and loading states

Code Organization

• Keep components small and focused
• Extract custom hooks for reusable logic
• Use TypeScript for type safety
• Write tests for critical user flows
