Setting Up Your Project

This will set up a new project with all the latest features and configurations.

The App Router

The App Router is the new way to structure your Next.js application. It uses the app/ directory instead of pages/.

Key Concepts

1. Layouts: Shared UI across routes
2. Loading States: Automatic loading UI
3. Error Handling: Built-in error boundaries
4. Server Components: Render on the server by default

Building Your First Page

Create a new page by adding a file in the app directory:

// app/about/page.tsx
export default function AboutPage() {
  return <h1>About Us</h1>
}

That's it! Your page is automatically routed to /about.

Conclusion

Next.js 14 makes it easier than ever to build performant web applications. The App Router provides a modern development experience with powerful features out of the box.
