Understanding React Server Components

React Server Components (RSC) represent a significant shift in how we think about React. Instead of moving all your components to the client, RSC allows you to keep much of your logic on the server.

Key Benefits

1. Smaller Client Bundles: Code used only on the server doesn't get sent to the browser.
2. Direct Backend Access: You can query your database or filesystem directly from your components.
3. Improved Data Fetching: Reduce waterfalls by fetching data on the server.

When to use Client Components?

You still need client components for interactivity, such as:

• Using useState or useEffect.
• Using browser APIs like localStorage or window.
• Listening to events like onClick.

Mastering the balance between Server and Client components is the key to building high-performance Next.js apps.
