Introduction to Next.js

Next.js is a powerful React framework that enables features like server-side rendering and static site generation for modern web applications.

Examples:

// pages/index.js
export default function Home() {
  return (
    <div>
      <h1>Welcome to Next.js!</h1>
    </div>
  )
}

Routing in Next.js

Next.js features a file-system based router built on the concept of pages, making routing simple and intuitive.

Examples:

// app/blog/[slug]/page.js
export default function BlogPost({ params }) {
  return (
    <article>
      <h1>Post: {params.slug}</h1>
    </article>
  )
}

Data Fetching

Next.js provides powerful data fetching methods for both server and client components.

Examples:

// Server Component
async function getData() {
  const res = await fetch('https://api.example.com/data')
  return res.json()
}

export default async function Page() {
  const data = await getData()
  
  return (
    <main>
      {data.map(item => (
        <div key={item.id}>{item.title}</div>
      ))}
    </main>
  )
}
