React Server Components for Beginners
Learn what are React Server Components (RSC) and how they leverage both server and client strengths, optimize efficiency, load times, and interactivity.

The serialized RSC payload can be then rendered at build time to static HTML, on the server upon request (SSR) or in the browser (CSR). During serialization, React replaces client components with references to the client-side JavaScript bundle which contains them.
You can pass serializable props from Server to Client components, but not functions, classes, or Dates. // Server Component import { LikeButton } from "./LikeButton"; // Client Component export default async function Post({ id }: { id: string }) { const post = await getPost(id); // Pass serializable data only return <LikeButton postId={post.id} initialLikes={post.likes} />; }
Introduced as an experimental feature in React 18 and now stabilizing in frameworks like Next.js 13+, Server Components allow us to render components entirely on the server, sending only the final HTML to the client.
This capability allows developers to perform actions like writing database queries directly inside their React components, which, to many long-time React users, might initially seem "absolutely wild." The good thing about server Components is that they never re-render.
React Server Components (RSC) is a new feature in the React ecosystem that allows React components to be rendered exclusively on the server side. Unlike traditional client components, which are rendered in the user's browser, server components ...
Server-side rendering is performed by the server components side of React Server Components and is like using the frontend renderer as a template engine. All non-interactive components are rendered on the server, sent to the browser, and then “hydrated” to provide interactivity.
React Server Components (RSCs) are a new component type introduced in React 18 and stabilized in React 19. Next.js picked it up right after it came out, and it has been production-ready since v13.
In late 2020, the React team introduced the "Zero-Bundle-Size React Server Components" concept. Since then, the React developer community has been experimenting with and learning how to apply this forward-looking approach. React has changed how we th...
