To structure Next.js apps, use server components and parallel routes for scalable data fetching and UI composition. This enforces server-first rendering patterns to reduce architectural drift and improve maintainability.

The best way to migrate from Pages Router to App Router is by adopting server-first rendering, route grouping, and streaming with Suspense. This migration updates your data fetching and loading patterns to leverage the new architecture effectively.

Streaming with Suspense in Next.js 14+ progressively renders and sends UI components to the client. This approach optimizes initial page load performance by streaming HTML chunks as data becomes available from the server.

Yes, you can use route interception and metadata strategies in Next.js App Router to handle navigation overrides and dynamically generate SEO metadata. These patterns ensure efficient UX composition and search engine optimization across your application.

You should use intercepting routes in Next.js when you need to override default navigation behavior, such as showing a modal or a specific layout context without losing the current page context. This pattern enhances user experience by preserving background route state.
