Frequently Asked Questions

The App Router is Next.js's new paradigm (v13+) built on React Server Components. It uses a file-system based router where folders define routes and special files like page.js, layout.js define UI. It supports layouts, streaming, and server-first rendering by default.

  • page.js – Unique UI of a route.
  • layout.js – Shared UI across pages in a segment.
  • loading.js – Instant loading state (Suspense-based).
  • error.js – Error boundary for a segment and its children.
  • template.js – Similar to layout but remounts on navigation.
  • not-found.js – UI when notFound() is called or no route matches.

TypeScript is strongly recommended for better developer experience, type safety, and auto-completion. Next.js has first-class TS support – just rename files to .ts/.tsx.

Yes, but it converts the component to a Client Component, which sends JavaScript to the browser. Use it only when you need interactivity (event listeners, state, browser APIs). Default to Server Components for better performance.

Create folder named like [slug] and the page component receives params prop. Optionally export generateStaticParams to pre-render static paths at build time.

Absolutely. Async Server Components are a core feature. You can fetch data directly inside the component with await, no need for getServerSideProps.
