Use Server Components by default for data fetching and static content in Next.js App Router. Switch to Client Components only when you need interactivity, state, or browser APIs to optimize performance.

The best way to fetch data in Next.js is using fetch APIs with built-in caching and revalidation patterns. Fetch directly inside Server Components to leverage automatic request memoization and granular cache control.

Implement parallel and intercepting routes in Next.js by mastering App Router file conventions. These advanced routing techniques enable simultaneous rendering of multiple pages and modal interception.

Yes, Next.js App Router supports image optimization and bundle analysis to enhance performance. Apply built-in image components and analyze bundle outputs to reduce load times and improve application scalability.

Common anti-patterns in Next.js applications include overusing Client Components, mismanaging data fetching caches, and improper metadata handling. Following established best practices prevents these structural and performance bottlenecks.
