Getting Started with Next.js

Next.js is a powerful React framework that enables features like server-side rendering, static site generation, and more without the need for complex configuration.

Why Next.js?

Next.js provides a great developer experience with all the features you need for production:

• Zero Config: Automatic compilation and bundling
• Hybrid Rendering: Server-side rendering and static site generation
• Fast Refresh: Instant feedback during development
• Built-in Routing: File-system based routing
• API Routes: Create API endpoints easily

Setting Up a Next.js Project

Getting started with Next.js is straightforward:

npx create-next-app@latest my-next-app
cd my-next-app
npm run dev

This will create a new Next.js application and start the development server on port 3000.

File-Based Routing

One of the best features of Next.js is its file-based routing system. Simply create files in the pages directory (or app directory if using the App Router), and Next.js will automatically create routes based on the file names.

For example:

• pages/index.js → /
• pages/about.js → /about
• pages/blog/[slug].js → /blog/:slug

Data Fetching

Next.js provides several ways to fetch data for your pages:

getStaticProps

export async function getStaticProps() {
  const res = await fetch('https://api.example.com/data')
  const data = await res.json()

  return {
    props: {
      data,
    },
  }
}

getServerSideProps

export async function getServerSideProps() {
  const res = await fetch('https://api.example.com/data')
  const data = await res.json()

  return {
    props: {
      data,
    },
  }
}

Conclusion

Next.js makes building React applications easier and more efficient. Its built-in features save development time and improve performance, making it an excellent choice for modern web development projects.

Whether you're building a simple blog or a complex web application, Next.js provides the tools you need to succeed.
