The Core Concept

By default, Next.js App Router uses React Server Components (RSC). These components are rendered exclusively on the server. They reduce the amount of JavaScript sent to the browser, leading to faster page loads. You can also securely access backend resources like databases directly inside them.

  const data = await getData();
  
  return (
    <main>
      <h1>Server Data:</h1>
      <pre>{JSON.stringify(data, null, 2)}</pre>
    </main>
  );

The Challenge

Build an SEO analyzer that fetches live data on the server without exposing API keys to the client.

Helpful Hints

•Keep your fetching logic in a Server Component. Pass only the parsed results to the UI.

Quick Knowledge Check

Can I use onClick in a Server Component?

No, event listeners require JavaScript in the browser. You must use a Client Component for interactivity.
