Introduction

Next.js 15 brings exciting new features and improvements to the React ecosystem. In this post, we'll explore what makes Next.js a great choice for building modern web applications.

Why Next.js?

Next.js solves many common challenges in web development:

• Server-side rendering for better performance and SEO
• File-based routing that's intuitive and scalable

First, create a new Next.js project:

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

This will set up a new project with all the latest features enabled.

Key Features

App Router

The App Router is a new paradigm for building Next.js applications. It uses React Server Components by default and provides powerful data fetching capabilities.

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

  return (
    <div>
      {posts.map((post) => (
        <article key={post.id}>
          <h2>{post.title}</h2>
          <p>{post.excerpt}</p>
        </article>
      ))}
    </div>
  )
}

Built-in Optimizations

Next.js automatically optimizes your application:

• Image optimization with the next/image component
• Font optimization with next/font
• Script optimization with next/script

Conclusion

Next.js 15 is a powerful framework that makes it easy to build fast, modern web applications. Whether you're building a blog, e-commerce site, or SaaS application, Next.js provides the tools you need to succeed.
