Use Server Components by default for data fetching and static content, switching to Client Components only when you need interactivity, state, or browser APIs. This strategy minimizes JavaScript sent to the client and optimizes performance.

Fetch data directly inside Server Components to leverage the App Router's async support. This approach avoids client-server waterfalls, reduces boilerplate, and allows you to implement effective caching strategies for improved performance.

Utilize Server Actions to handle data mutations directly from your components. This pattern allows secure data modifications without creating dedicated API routes, streamlining form submissions and database updates.

The App Router provides built-in caching mechanisms for data fetching and rendering. Implement effective caching strategies by understanding request memoization, data cache, full route cache, and router cache to maximize performance.

Common anti-patterns include unnecessary use of Client Components, over-fetching data, and poor project structure. Addressing these issues through proper file conventions and component strategy ensures maintainable web applications.

Build robust API endpoints using the App Router's file conventions. Apply best practices for request validation, error handling, and route organization to maintain secure and scalable backend logic.
