File-Based Routing in Next.js

Next.js uses a pages directory or app directory (in App Router) to automatically generate routes.

Example:

  • /pages/index.js/
  • /pages/about.js/about
  • /pages/blog/[slug].js/blog/:slug

Dynamic routes are created using brackets []. Catch-all routes use [...slug].js.

Benefits

  • No manual route definitions.
  • Automatic code splitting per route.
  • Easy nested routing with folders.
