In this video, we dive deep into the Next.js App Router, the powerful routing system introduced in version 13+ that utilizes the app/ directory. We explore how this architecture shifts from the traditional Pages Router to a more performance-oriented model that supports Server Components by default. What you will learn: • App Router vs. Pages Router: Understand the shift from client-side React components to server-side performance improvements and streaming. • Server vs. Client Components: Learn why Server Components are ideal for SEO and data fetching since they send no JavaScript to the browser, and how to use the "use client" directive for interactive elements. • Folder-Based Routing: See how page.js defines your routes while folders define your URL segments. • Layouts and UI: Discover how to use layout.js to create shared UI components that persist across route changes, preventing unnecessary re-renders of headers and footers. • Enhanced User Experience: How to implement loading.js for instant loading states and error.js for robust error boundaries. • Data Fetching & Performance: How to fetch data directly inside Server Components using fetch with automatic caching and revalidation. • Advanced Navigation: Using hooks like useRouter and usePathname within Client Components to manage navigation and identify current paths. Mastering these concepts will allow you to leverage Streaming and Suspense to send page chunks to the browser, significantly improving perceived performance
