Introduction | Next.js (original) (raw)

Welcome to the Next.js documentation!

What is Next.js?

Next.js is a React framework for building full-stack web applications. You use React Components to build user interfaces, and Next.js for additional features and optimizations.

It also automatically configures lower-level tools like bundlers and compilers. You can instead focus on building your product and shipping quickly.

Whether you're an individual developer or part of a larger team, Next.js can help you build interactive, dynamic, and fast React applications.

How to use the docs

The docs are organized into 4 sections:

• Getting Started: Step-by-step tutorials to help you create a new application and learn the core Next.js features.
• Guides: Tutorials on specific use cases, choose what's relevant to you.
• Deep Dive: In-depth explanations on how Next.js works.
• API Reference: Detailed technical reference for every feature.

Use the sidebar to navigate through the sections, or search (Ctrl+K or Cmd+K) to quickly find a page.

App Router and Pages Router

Next.js has two different routers:

• App Router: The newer router that supports new React features like Server Components.
• Pages Router: The original router, still supported and being improved.

At the top of the sidebar, you'll notice a dropdown menu that allows you to switch between the App Router and the Pages Router docs.

Pre-requisite knowledge

Our documentation assumes some familiarity with web development. Before getting started, it'll help if you're comfortable with:

• HTML
• CSS
• JavaScript
• React

If you're new to React or need a refresher, we recommend starting with our React Foundations course, and the Next.js Foundations course that has you building an application as you learn.

Accessibility

For the best experience when using a screen reader, we recommend using Firefox and NVDA, or Safari and VoiceOver.

If you have questions about anything related to Next.js, you're always welcome to ask our community on GitHub Discussions, Discord, X (Twitter), and Reddit.
