Getting Started

Installation

Create a new Next.js project using the following command:

Follow the prompts to configure your project. You can choose:

• TypeScript or JavaScript
• ESLint configuration
• Tailwind CSS
• App Router or Pages Router

Project Structure

With the App Router, your project structure will look like this:

app/
  ├── layout.tsx      # Root layout

  ├── about/
  │   └── page.tsx   # About page
  └── blog/
      └── page.tsx   # Blog listing

Building Your First Page

Let's create a simple page:

// app/about/page.tsx
export default function About() {
  return (
    

      
About Us
      
Welcome to our website!
    
  );
}

Data Fetching

Next.js 14 makes data fetching simple with async Server Components:

// app/blog/page.tsx
async function getPosts() {
  const res = await fetch('https://api.example.com/posts');
  return res.json();
}

export default async function Blog() {
  const posts = await getPosts();
  
  return (
    

      {posts.map(post => (
        

          
{post.title}
        
      ))}
    
  );
}

Deployment

Deploying your Next.js app is straightforward:

1. Vercel (Recommended): Push to GitHub and import to Vercel
2. Netlify: Connect your repository
3. Self-hosted: Build and deploy anywhere Node.js runs
