React Server Components Integration
Building on the advancements in the `app` directory, Next.js 13 fully embraces React Server Components. These components are rendered on the server and sent to the client as HTML, reducing the amount of JavaScript that needs to be executed on the client side.
Syntax:
// app/userProfile.js
import React from 'react';
export default async function UserProfile({ userId }) {
const user = await fetchUser(userId);
return (
<div>
<h1>{user.name}</h1>
<p>{user.email}</p>
</div>
);
}
async function fetchUser(userId) {
const res = await fetch(`https://api.example.com/users/${userId}`);
return res.json();
}
Advantages:
- Performance: By offloading rendering to the server, the client-side load is significantly reduced.
- SEO-Friendly: Enhanced SEO capabilities as content is readily available in the HTML.
- Hydration: Only interactive parts of the page are hydrated, leading to faster interactive times.
