Getting Started with Next.js App Router

Next.js has become the go-to framework for building modern React applications. With the introduction of the App Router, the developer experience has improved significantly.

Why Next.js?

Next.js provides a great foundation for building web applications with features like:

• Server Components — render on the server by default for better performance
• File-based routing — create routes by adding files to the app directory
• Built-in optimizations — automatic image, font, and script optimization

Creating Your First App

Getting started is straightforward:

npx create-next-app@latest my-app

This scaffolds a new project with TypeScript, Tailwind CSS, and the App Router configured out of the box.

Project Structure

A typical Next.js project looks like this:

my-app/
├── src/
│   └── app/
│       ├── layout.tsx    # Root layout
│       ├── page.tsx      # Home page
│       └── globals.css   # Global styles
├── public/               # Static assets
└── package.json

What's Next?

From here, you can start building pages, adding API routes, and integrating your favorite libraries. The Next.js documentation is an excellent resource for learning more.

Tip: Use the --turbopack flag during development for faster builds.
