Next.js App Router patterns structure server components and data fetching by establishing server/client boundaries, leveraging streaming, and applying file conventions to build scalable React apps efficiently.

Migrating from Next.js Pages Router to App Router involves restructuring routes using new file conventions, moving data fetching to server components, and adapting layouts to optimize SSR and SSG performance.

Parallel routes and Server Actions work in modern React applications by utilizing advanced App Router file conventions to render multiple components simultaneously and handle server-side mutations directly.

Understanding server/client boundaries is required to build scalable Next.js apps because it dictates where data fetching occurs, how streaming is applied, and how server components optimize rendering.

Use streaming and Server Components for data fetching in Next.js when you need to progressively render UI chunks, improve initial load performance, and achieve ISR-like behavior for dynamic content.

Limitations of Next.js App Router file conventions include the complexity of managing parallel routes and server/client boundaries, requiring careful architectural planning to avoid performance bottlenecks during migration.
