React Server Components: The Future of Data Fetching

Sun, 20 Aug 2023 00:00:00 +0000

React Server Components (RSC) run on the server only-they never ship component logic to the client. That enables direct database access and smaller JavaScript bundles.

Server vs Client Components

// app/page.js - Server Component (default in App Router)
async function ProductList() {
  const products = await db.products.findMany();
  return (
    <ul>
      {products.map((p) => <li key={p.id}>{p.name}</li>)}
    </ul>
  );
}

Add 'use client' only when you need hooks, event handlers, or browser APIs.
