Getting Started with Next.js 15

Next.js 15 represents a major leap forward in React-based web development. With improved performance, better developer experience, and powerful new features, it's easier than ever to build modern web applications.

What's New in Next.js 15

The latest version brings several exciting updates:

• Turbopack - Lightning-fast bundler that speeds up your development workflow
• Server Actions - Simplified data mutations without API routes
• Improved App Router - Better routing with enhanced layouts and error handling
• React Server Components - Build faster apps with less client-side JavaScript

Getting Started

Installing Next.js is straightforward with the create-next-app tool:

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

This sets up a new Next.js project with all the recommended configurations.

Project Structure

Next.js 15 uses the App Router by default, which organizes your code in an intuitive way:

• app/ - Contains all your routes and pages
• components/ - Reusable React components
• lib/ - Utility functions and helpers
• public/ - Static assets like images

Building Your First Page

Creating a new page is as simple as adding a file to the app directory:

export default function AboutPage() {
  return (
    <div>
      <h1>About Us</h1>
      <p>Welcome to our site!</p>
    </div>
  )
}

Styling with Tailwind CSS

Next.js works seamlessly with Tailwind CSS for utility-first styling. The integration is automatic when you create a new project with create-next-app.

Data Fetching

Next.js 15 makes data fetching simple with 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>{data.title}</div>
}

Conclusion

Next.js 15 provides an excellent foundation for building modern web applications. With its focus on performance, developer experience, and best practices, it's a great choice for projects of any size.
