Here are key practices to build efficient and maintainable React applications:

1. Component Design

  • Single Responsibility: Each component should handle one specific task (e.g., <Button />, <Header />)
    react_component
  • Avoid Deep Nesting: Keep component hierarchies flat for better readability
  • Use Props for Data Flow: Pass data through props instead of global state

2. State Management

  • Lift State Up: Centralize state in parent components when needed
  • Immerse in Context API: Use Context for cross-component state sharing
    state_management
  • Prefer Local State: Use useState/useReducer for component-specific logic

3. Performance Optimization

  • Memoize Components: Use React.memo or useMemo to avoid unnecessary re-renders
  • Lazy Load: Implement React.lazy and Suspense for code splitting

  • Use Profiler: Analyze performance with React Profiler tool

4. Code Quality

  • TypeScript: Add type safety to your components
  • Code Splitting: Break apps into smaller chunks using React.lazy
  • Testing: Write unit tests with Jest and snapshot testing
