Everything you need to master RSC

Discover the cutting-edge capabilities that make React Server Components the future of modern web development.

01

Zero-Bundle Server Logic

Server components run exclusively on the server. Heavy computations, data fetching, and business logic never reach the client bundle.

02

Streaming & Suspense

Watch content progressively render as it becomes ready. No loading spinners—just smooth, incremental page building with React Suspense.

03

React 19 Compiler

Automatic memoization and optimization without manual useMemo or useCallback. The compiler handles performance for you.

04

Server-First Architecture

Experience the paradigm shift of server components. Direct database access, async components, and seamless server-client composition.

Journey

Your Learning Path

Four progressive steps to master React Server Components and build high-performance applications.

01

Server Components

Understand how components run on the server by default, reducing JavaScript bundle size and enabling direct access to backend resources.

Explore this step
UserProfile.tsx
1// No 'use client' — zero bundle cost
2async function UserProfile({ id }: { id: string }) {
3 const user = await db.users.findById(id)
4 const posts = await db.posts.byUser(id)
5
6 return (
7 <article className="profile">
8 <h1>{user.name}</h1>
9 <p>{user.email}</p>
10 <PostList posts={posts} />
11 </article>
12 )
13}
02

Client Boundaries

Learn strategic placement of 'use client' directives. See how to compose server and client components for optimal performance.

Explore this step
LikeButton.tsx
1'use client'
2
3function LikeButton({ postId }: { postId: string }) {
4 const [liked, setLiked] = useState(false)
5
6 return (
7 <button
8 onClick={() => setLiked(!liked)}
9 className="flex items-center gap-2"
10 >
11 {liked ? '❤️ Liked' : '🤍 Like'}
12 </button>
13 )
14}
03

Data Fetching Patterns

Explore async/await in components, streaming with Suspense, and parallel data fetching without traditional API routes.

Explore this step
Dashboard.tsx
1async function Dashboard() {
2 // Parallel fetch — no waterfalls
3 const [user, posts] = await Promise.all([
4 fetchUser(),
5 fetchPosts(),
6 ])
7
8 return <UserDashboard user={user} posts={posts} />
9}
10
11// Stream with Suspense boundary
12<Suspense fallback={<DashboardSkeleton />}>
13 <Dashboard />
14</Suspense>
04

React 19 Features

Experience the React Compiler, enhanced hooks, server actions, and the future of React architecture in a production-ready app.

Explore this step
EditForm.tsx
1const [state, action, isPending] =
2 useActionState(
3 async (prev: State, formData: FormData) => {
4 const name = formData.get('username')
5 await updateProfile(name)
6 return { status: 'success', name }
7 },
8 { status: 'idle' }
9 )
10
11// No useState, no loading flags —
12// React tracks it all automatically
