Introduction to React Server Components in Next.js

A New Era for React

React Server Components (RSC) represent a fundamental shift in how we build React applications. By moving component execution to the server, we can drastically reduce the amount of JavaScript sent to the client.

Why Server Components?

• Automatic Code Splitting: Only the dynamic parts of your app need JavaScript.
• Zero Bundle Size Impact: Code that only runs on the server doesn't add to the client bundle.
• Direct Access to Backend: Query databases directly from your components.

Client vs. Server Components

Understanding when to use 'use client' is key. Use Server Components by default, and only opt into Client Components for interactivity, browser APIs, or state.
