React Server Components 101

Understanding the shift in React architecture.

React Server Components (RSC) represent the biggest shift in the React ecosystem since Hooks. They allow components to render exclusively on the server, reducing the bundle size sent to the client.

Why RSC?

  1. Zero Bundle Size: Server components behave like templates. Their code isn't downloaded by the browser.
  2. Direct Backend Access: Query your database directly inside your component. No more useEffect fetching waterfalls.
  3. Automatic Code Splitting: Client components imported by server components are automatically code-split.

The Mental Model

Think of your app as a skeleton rendered on the server, with interactive "islands" of hydration (Client Components) sprinkled in where user interaction is needed. It's the best of both worlds: the SEO and performance of SSR with the interactivity of SPAs.
