Getting Started with Next.js 15

Next.js 15 brings revolutionary changes to how we build web applications. In this comprehensive guide, we'll explore the key features and improvements that make Next.js 15 the go-to framework for production-ready React applications.

What's New in Next.js 15?

Next.js 15 introduces several groundbreaking features:

• Turbopack - Lightning-fast bundler that's 700x faster than Webpack
• Server Components by Default - Improved performance with zero-bundle components
• Enhanced Caching - Smarter caching strategies for better performance
• Improved TypeScript Support - Better type safety and developer experience

The App Router Revolution

The App Router is now stable and recommended for all new projects. Here's why it's game-changing:

File-Based Routing

// app/blog/[slug]/page.tsx
export default async function BlogPost({ params }) {
  const { slug } = await params;
  return <div>Blog post: {slug}</div>;
}

Server Components

Server Components render on the server, reducing JavaScript bundle size and improving performance:

// This component runs on the server only
export default async function ServerComponent() {
  const data = await fetch('https://api.example.com/data');
  return <div>{JSON.stringify(data)}</div>;
}

Key Benefits

1. Better Performance - Automatic code splitting and optimizations
2. SEO-Friendly - Server-side rendering out of the box
3. Developer Experience - Hot module replacement and fast refresh
4. Production-Ready - Used by companies like Netflix, TikTok, and Nike
