Enhanced Data Fetching with ‘app’ Directory
Next.js 13 introduces a new `app` directory that revolutionizes how data fetching and layout composition are handled. This change aligns with React’s upcoming server components, allowing developers to fetch data directly in the component tree without additional client-side requests.
Syntax:
// app/page.js
import React from 'react';
export default async function Page() {
const data = await fetchData();
return (
<div>
<h1>Data from Server</h1>
<pre>{JSON.stringify(data, null, 2)}</pre>
</div>
);
}
async function fetchData() {
const res = await fetch('https://api.example.com/data');
return res.json();
}
Features:
- Server Components: Fetch data on the server, reducing the client-side bundle size and improving page load times.
- Colocation: Place components and their data fetching logic together, making the codebase more intuitive and maintainable.
- Improved Layouts: Nested layouts become simpler to manage and render efficiently.
