Use Server Components for data fetching and static content to reduce bundle sizes. Use Client Components only when you need interactivity, state, or browser APIs, keeping them as leaf nodes in your component tree.

Fetch data directly inside Server Components to leverage the network during server rendering. This approach eliminates client-server waterfalls, reduces manual caching logic, and improves overall page performance.

Optimize Next.js performance by using the built-in Image Component, minimizing Client Components, and relying on Server Components. Proper metadata handling and strategic caching also significantly reduce bundle sizes and improve load times.

Yes, you can implement robust API routes using App Router conventions. The framework provides structured file conventions for creating API handlers that process requests and return responses efficiently within your application architecture.

Server Actions allow you to mutate data directly from React components without manually creating API endpoints. They execute securely on the server, streamlining form submissions and data updates while maintaining type safety.

Next.js App Router provides built-in caching mechanisms for data fetching and rendering. You should understand the underlying caching principles to configure them correctly, avoiding common pitfalls while building scalable applications.
