The Composition Challenge
You often need interactivity (Client) wrapping data-heavy UI (Server). The trick is composing them so Server Components are not pulled into the client bundle.
The One-Way Rule
A Client Component cannot import a Server Component, because importing would force it to run on the client. But it can render one passed as children.
Passing as Children
Render a Server Component inside a Client Component by passing it through props from a parent Server Component.
export default function Page() {
return (<ClientShell><ServerContent /></ClientShell>);
}The Client Shell
The Client Component receives the already-rendered Server output as children and never needs to know how it was built.
"use client";
export default function ClientShell({ children }) {
const [open, setOpen] = useState(false);
return (<div>{children}<button onClick={() => setOpen(!open)}>Toggle</button></div>);
}Why This Works
The Server Component renders on the server; only its output (serialized RSC payload) reaches the client. The Client Component just slots it in — no server code shipped.
Props Must Be Serializable
Props passed from Server to Client Components must be serializable. You cannot pass functions, class instances, or Dates without care — but you can pass plain data and JSX children.
Moving Client Boundaries Down
Keep "use client" as deep in the tree as possible. A small leaf Client Component keeps most of the tree server-rendered and the bundle small.
Context Providers
Client context providers wrap Server children fine: define the provider as a Client Component and pass server-rendered children through it.
"use client";
export function ThemeProvider({ children }) {
return <Ctx.Provider value={theme}>{children}</Ctx.Provider>;
}Avoiding Accidental Client Code
Importing a library that uses browser APIs into a Server Component breaks it. Isolate such code behind a Client Component boundary.
Interleaving Example
You can deeply interleave: Server layout, Client sidebar toggler, Server content, Client like-button — each boundary minimal and intentional.
Mental Model
Think of Client Components as holes in a server-rendered tree. Data flows down as props/children; interactivity lives only where needed.
Quick Check
How do you render a Server Component inside a Client Component?
Recap
You learned the key composition pattern: Client Components cannot import Server Components but can render them as children. Keep client boundaries small and deep, pass serializable props, and treat Client Components as interactive holes in a server-rendered tree.
