Next.js

What is Next.js?

Next.js is a React framework created by Vercel that adds routing, rendering, data fetching, and full-stack API capabilities on top of React. Instead of hand-assembling a router, a bundler, and a server-rendering setup yourself, Next.js gives you all of it out of the box, so you can focus on building the actual product.

Where is Next.js Used?

Next.js powers a huge share of production React applications today. Here are the major application areas:

Why Learn Next.js?

A Server Component Fetching Data

Here is a basic Next.js page that demonstrates several important App Router concepts:

// app/products/page.tsx — a Server Component
async function getProducts() {
  const res = await fetch('https://api.example.com/products', {
    next: { revalidate: 60 }, // ISR: refresh at most every 60s
  });
  return res.json();
}

export default async function ProductsPage() {
  const products = await getProducts();

  return (
    <ul>
      {products.map((p) => (
        <li key={p.id}>{p.name} — ${p.price}</li>
      ))}
    </ul>
  );
}
