What this example teaches

Caching

Output

NextJS pre-renders page static HTML during build or dynamic JSON on runtime fetch.

Line-by-line explanation

  • Line 1 sets up the Caching example: export default function Page() {.
  • Line 2 exposes the output so you can verify the behavior: return <section className="p-6"><h1>Caching</h1><p>NextJS App Router pre-rendered page.</p></section>;.
  • Line 3 adds one required part of the working pattern: }.

Why this example is useful

This example is useful because it isolates caching without surrounding noise, so you can see the idea clearly.

Where it is used in real projects

Caching appears in real Next.js work when a feature needs a clear pattern that can be reviewed and changed safely.

Beginner variation

Change one label, value or condition in the Caching example and run it again.

Advanced variation

Combine Caching with validation, error handling or reusable structure.
