Choosing between Server Components and Client Components in Next.js App Router requires analyzing your component's data and interactivity needs, using a decision tree to default to server components and only opting into client components when state or browser APIs are necessary.

The best data fetching patterns for Next.js App Router include default caching, time-based revalidation, and no-store strategies, allowing you to optimize performance by selecting the appropriate fetch behavior for static or dynamic data requirements.

Using Server Actions for data mutations in Next.js involves defining asynchronous functions that run securely on the server to handle form submissions and database updates without creating separate API endpoints.

The caching strategy for Next.js performance optimization involves leveraging multiple cache layers and revalidation methods to control data freshness, ensuring efficient data handling and reduced server load.

Common anti-patterns and project structure mistakes in Next.js include improper route organization and misusing file conventions, which can be avoided by following established best practices for API routes and component placement.

You need intermediate to advanced Next.js knowledge to effectively use App Router routing principles, as mastering file conventions, route organization, and performance optimization requires understanding underlying server and client boundaries.
