Getting Started with Next.js

Next.js has revolutionized the way we build React applications. Let's explore why it's become so popular and how to get started.

Why Next.js?

Next.js provides several key features out of the box:

• Server-Side Rendering (SSR)
• Static Site Generation (SSG)
• API Routes
• File-based Routing

Code Example

Here's a simple Next.js page component:

import { useState } from 'react';
 
export default function HomePage() {
  const [count, setCount] = useState(0);
 
  return (
    <div className="p-4">
      <h1 className="text-2xl font-bold">Welcome to Next.js</h1>
      <button 
        onClick={() => setCount(count + 1)}
        className="px-4 py-2 bg-blue-500 text-white rounded"
      >
        Count: {count}
      </button>
    </div>
  );
}

Features in Action

Let's look at some key Next.js features:

1. API Routes

// app/api/hello/route.ts
export async function GET() {
  return Response.json({ message: 'Hello, World!' });
}

2. Dynamic Routes

Next.js makes it easy to create dynamic routes:

// app/[id]/page.tsx
export default function DynamicPage({ params }) {
  return <h1>Post ID: {params.id}</h1>;
}

Conclusion

Next.js provides a robust framework for building modern web applications. Whether you're building a small personal site or a large enterprise application, Next.js has the tools and features you need.
