Next.js App Router best practices recommend using a decision tree to choose between Server and Client components, reserving Client components for interactivity while defaulting to Server components to maximize performance and maintainability.

Best practices for data fetching in Next.js App Router involve implementing optimal patterns for caching and revalidation within Server components, ensuring structured data retrieval that maximizes web application performance without unnecessary client-side requests.

To optimize performance and bundle sizes in Next.js, follow best practices for optimizing images and code bundles. Structured App Router development patterns ensure faster load times and efficient resource delivery for modern web applications.

Handling routing and API routes in Next.js requires implementing effective file-based routing, advanced routing patterns, and structured API route designs. Following App Router principles ensures maintainable and efficient application architecture.

Use Server Actions instead of API routes in Next.js when handling mutations directly within Server components to streamline data submission. App Router best practices outline specific patterns for caching, metadata handling, and revalidation with Server Actions.

This Next.js guidance applies to both new and existing web applications. Developers building new projects use it to structure correctly from the start, avoiding common pitfalls, while existing apps adopt these patterns to maximize performance and maintainability.
