Understanding Next.js Routing

Routing in Next.js App Router is file-system based. Each folder becomes a route segment, and each `page.tsx` becomes a route entry.

Core concepts

  • `app/blog/page.tsx` maps to `/blog`
  • `app/blog/[slug]/page.tsx` maps to `/blog/:slug`
  • `layout.tsx` composes shared UI for nested segments

Why it matters

Clear route structure keeps your app scalable and makes nested UIs much easier to reason about.
