# Getting Started with Next.js 15
Next.js 15 brings exciting new features and improvements that make building React applications even more powerful and developer-friendly. In this guide, we'll explore the key features and how to get started.
## What's New in Next.js 15
### App Router (Stable)
The App Router is now the recommended way to build Next.js applications. It provides:
- **Server Components** by default
- **Nested layouts** for better code organization
- **Loading and error states** built-in
- **Streaming** for better performance
### Server Components
Server Components allow you to render components on the server, reducing the JavaScript bundle size and improving performance:
```tsx
// This component runs on the server
export default async function BlogPost() {
const posts = await fetch('https://api.example.com/posts')
return (
<div>
{posts.map(post => (
<article key={post.id}>{post.title}</article>
))}
</div>
)
}
```
## Getting Started
1. **Create a new Next.js project:**
```bash
npx create-next-app@latest my-app --typescript --tailwind --eslint
```
2. **Navigate to your project:**
```bash
cd my-app
```
3. **Start the development server:**
```bash
npm run dev
```
## Best Practices
- Use Server Components by default, Client Components when needed
- Leverage the new `loading.tsx` and `error.tsx` files
- Organize your routes using the file-system based routing
- Take advantage of built-in optimizations like Image and Font optimization
Next.js 15 makes it easier than ever to build fast, scalable React applications. Start exploring these features in your next project!
