Getting Started with Next.js 15: A Comprehensive Guide

Introduction

Next.js has become the go-to framework for building modern React applications. With the release of Next.js 15, developers have access to even more powerful features that make building web applications faster and more enjoyable.

Why Choose Next.js?

Next.js solves many common problems that developers face when building React applications:

• Server-Side Rendering (SSR): Improve SEO and initial page load performance
• Static Site Generation (SSG): Pre-render pages at build time for maximum performance
• API Routes: Build your backend and frontend in the same project
• File-based Routing: No need to configure complex routing libraries
• Built-in Optimizations: Automatic code splitting, image optimization, and more

Getting Started

To create a new Next.js project, run the following command:

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

This will create a new Next.js application with all the necessary dependencies and configuration.

Project Structure

A typical Next.js project has the following structure:

my-app/
├── app/              # App Router (Next.js 13+)
│   ├── layout.tsx    # Root layout
│   └── page.tsx      # Home page
├── public/           # Static assets
├── components/       # React components
└── lib/              # Utility functions

Creating Your First Page

In Next.js 15, pages are created using the App Router. Here's a simple example:

export default function Home() {
  return (
    <main className="flex min-h-screen flex-col items-center justify-center p-24">
      <h1 className="text-4xl font-bold">Welcome to Next.js 15</h1>
      <p className="mt-4 text-xl">The React Framework for Production</p>
    </main>
  )
}

Data Fetching

Next.js 15 makes data fetching simple with React Server Components:

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 <div>{/* Render your data */}</div>
}

Deployment

Deploying a Next.js application is incredibly easy with Vercel:

1. Push your code to GitHub
2. Import your repository in Vercel
3. Deploy with one click

That's it! Your application is now live with automatic HTTPS, CDN, and more.

Conclusion

Next.js 15 is a powerful framework that makes building modern web applications easier than ever. With built-in optimizations, excellent developer experience, and seamless deployment, it's the perfect choice for your next project.
