You build web apps. You need React Server Components (RSC). They change how you ship code.

RSCs run on the server. They send HTML to the browser. The browser does not get the JavaScript logic. This makes your site fast.

SSR sends HTML but still ships all JavaScript. RSCs keep logic on the server. The code never leaves the kitchen.

React now has three component types:

• Server Components: Run on the server. Access databases and APIs. No state.
• Client Components: Run in the browser. Handle clicks and state. Use the use client tag.
• Shared Components: Run in both.

Why use RSC?

• Smaller bundles. Faster loads.
• Direct backend access. No extra API layers.
• Better SEO.
• Higher security. API keys stay on the server.
• Faster content delivery.

Next.js uses RSC by default. Use server components for data. Use client components for buttons.

Server Actions work with RSC. They let you run server functions from the UI. You no longer need separate API routes.

Avoid these mistakes:

• Do not use useState in server components.
• Only pass plain data to client components.
• Do not use use client everywhere.

Rule of thumb: Push interactivity to the edges. Keep outer layers as server components.

The gap between frontend and backend is closing. Build server first. Your apps will be faster.
