To migrate from Next.js Pages Router to App Router, adapt your project to use the app directory and enable server components by default. You then implement layout.tsx, page.tsx, error.tsx, and loading.tsx files to structure your application using modern patterns.

Next.js Server Components optimize rendering and performance by fetching data directly on the server. You should structure your app using nested layouts and fetch data within these server-driven UI components to ensure scalable and efficient application architecture.

You use server actions and middleware in Next.js App Router by implementing them alongside your page.tsx and layout.tsx files. This approach handles form submissions and request interception within your scalable Next.js project architecture.

You should use nested layouts in Next.js App Router when building scalable applications that require shared UI across multiple routes. This pattern structures routing and data-fetching efficiently, ensuring consistent layout composition across your project.

Yes, Next.js App Router requires server components by default to optimize rendering and performance. All components inside the app directory are server-driven unless explicitly marked as client components, ensuring a server-first UI architecture.
