Getting Started with Next.js 16 App Router

Introduction

Next.js 16 brings significant improvements to the developer experience with deeper React 19 integration, improved Turbopack support, and a more refined App Router.

In this guide, we'll explore the key features and patterns you need to know.

Setting Up Your Project

Getting started is straightforward:

This gives you a fully configured project with TypeScript, Tailwind CSS, and the App Router.

Server Components by Default

One of the biggest paradigm shifts in Next.js is that all components are Server Components by default. This means they render on the server and send only HTML to the client.

You only need the "use client" directive when your component:

• Uses React hooks like `useState` or `useEffect`
• Handles browser events like `onClick`
• Accesses browser-only APIs

Data Fetching

Data fetching in Server Components is beautifully simple:

No useEffect, no loading states to manage manually, no client-side waterfall.

Conclusion

Next.js 16 continues to push the boundaries of what's possible with React. The combination of Server Components, streaming, and the App Router creates a powerful foundation for modern web applications.
