Setting up the App Router involves creating a basic layout and page structure within the app directory. This establishes the optimal routing foundation for full-stack React development using React Server Components and Server Actions.

React Server Components render exclusively on the server to reduce bundle size, while Server Actions execute server-side mutations triggered from the client. Both are core architectural patterns within the Next.js App Router.

Fixing data fetching issues requires implementing correct caching strategies and streaming patterns. The architecture provides optimized server-side data fetching mechanisms to prevent common pitfalls and improve deployment performance.

Yes, Server Actions handle server-side mutations triggered directly from client components. They integrate seamlessly with the App Router architecture to enable modern full-stack React development without separate API endpoints.

Common pitfalls include incorrect caching configurations, improper use of Server Components, and inefficient data fetching patterns. Addressing these ensures proper streaming, deployment optimization, and stable full-stack React architecture.
