Getting Started with Next.js 15

Next.js 15 brings exciting new features and improvements that make building modern web applications even easier. In this post, we'll explore the key features and how to get started.

What's New in Next.js 15

Turbopack as Default

Next.js 15 now uses Turbopack as the stable default bundler, offering significantly faster build times and hot module replacement.

React 19 Support

Full support for React 19 brings new features like:

• Improved Server Components
• Enhanced Suspense boundaries
• Better error handling

Setting Up Your Project

To create a new Next.js 15 project, run:

npx create-next-app@latest my-app

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

Key Features

App Router

The App Router provides a more intuitive way to define routes using the file system:

app/
  page.tsx        # Home page
  about/
    page.tsx      # About page
  blog/
    [slug]/
      page.tsx    # Dynamic blog post page

Server Components

By default, all components in the app directory are Server Components. This means they render on the server and send HTML to the client.

// This is a Server Component
async function BlogList() {
  const posts = await getPosts();

  return (
    <ul>
      {posts.map(post => (
        <li key={post.id}>{post.title}</li>
      ))}
    </ul>
  );
}

Conclusion

Next.js 15 continues to push the boundaries of what's possible with React. Whether you're building a simple blog or a complex application, it provides the tools you need to succeed.

Happy coding!
