Learn Next.js

Build structured React applications with routing, server-side features, and production-ready performance.

Why Learn Next.js?

Built on React

Next.js adds routing, structure, and performance features to React.

Production Ready

SEO optimization, file-based routing, and server rendering patterns.

Project Setup

Create a new Next.js project with the official starter.

npx create-next-app@latest my-next-app
cd my-next-app
npm run dev
Local development server starts on http://localhost:3000

Pages and App Structure

The app directory helps organize pages and layouts. Try creating a page component!

Console Output

File-Based Routing

Next.js uses the file system for routing. Create pages by adding files to the app directory.

Reusable Components

Components can be reused across multiple pages. Build a navigation component!

Data Fetching in Next.js

Next.js supports server-side data fetching with async components.

// Real Next.js data fetching:
export default async function Page() {
  const res = await fetch('https://api.example.com/posts')
  const posts = await res.json()
  return <div>{posts.length} posts loaded</div>
}
