How to integrate Server Components into existing React apps?
Integrating Server Components depends on your tech stack, but generally, here’s the path:
1. Use a framework that supports Server Components
As of now, Next.js (from version 13 and above) offers the best support for Server Components, using the /app
directory and server
/client
conventions.
2. Mark Components as Client or Server
By default, components are Server Components. To create a Client Component (for interactive parts), add a 'use client';
directive at the top of the file.
Example:
// This is a Server Component (default) export default async function ProductsList() { const products = await fetchProductsFromDB(); return <div>{products.map(p => <div key={p.id}>{p.name}</div>)}</div>; } // Client Component 'use client'; export default function Button() { return <button onClick={() => alert('Clicked!')}>Click me</button>; }
3. Mix Client and Server Components
You can render Client Components inside Server Components but not the other way around.
4. Update your data-fetching and routing
Server Components allow you to fetch data right inside components without useEffect
, simplifying a lot of logic.
