Building Scalable React Applications: Architecture Patterns

# Building Scalable React Applications: Architecture Patterns As React applications grow in complexity, maintaining a clean and scalable architecture becomes crucial. In this article, we'll explore patterns and strategies for building maintainable React applications. ## Folder Structure A well-organized folder structure is the foundation of a scalable application: ``` src/ components/ common/ features/ pages/ hooks/ utils/ services/ store/ types/ ``` ## State Management Choose the right state management solution based on your needs: - **Local State**: For component-specific data - **Context API**: For shared state across components - **Redux/Zustand**: For complex global state - **Server State**: Use React Query or SWR ## Component Patterns ### Container/Presentational Pattern Separate logic from presentation: ```typescript // Container const UserContainer = () => { const { data, loading } = useUser(); return ; }; // Presentational const UserView = ({ data, loading }) => { // Pure presentation logic }; ``` ## Performance Optimization 1. Use React.memo for expensive components 2. Implement code splitting with React.lazy 3. Optimize re-renders with useMemo and useCallback 4. Virtualize long lists 5. Use production builds ## Conclusion Building scalable React applications requires careful planning and adherence to proven patterns. Start with a solid foundation and iterate based on your specific needs.
