Getting Started

Welcome to the Next.js documentation!

If you're new to Next.js, we recommend starting with the learn course.

The interactive course with quizzes will guide you through everything you need to know to use Next.js.

If you have questions about anything related to Next.js, you're always welcome to ask our community on GitHub Discussions.

System Requirements

• Node.js 12.22.0 or later
• MacOS, Windows (including WSL), and Linux are supported

Automatic Setup

We recommend creating a new Next.js app using create-next-app, which sets up everything automatically for you. To create a project, run:

npx create-next-app@latest
# or
yarn create next-app
# or
pnpm create next-app

If you want to start with a TypeScript project you can use the --typescript flag:

npx create-next-app@latest --typescript
# or
yarn create next-app --typescript
# or
pnpm create next-app -- --typescript

After the installation is complete:

• Run npm run dev or yarn dev or pnpm dev to start the development server on http://localhost:3000
• Visit http://localhost:3000 to view your application
• Edit pages/index.js and see the updated result in your browser

For more information on how to use create-next-app, you can review the create-next-app documentation.

Manual Setup

Install next, react and react-dom in your project:

npm install next react react-dom
# or
yarn add next react react-dom
# or
pnpm add next react react-dom

Open package.json and add the following scripts:

{
  "scripts": {
    "dev": "next dev",
    "build": "next build",
    "start": "next start",
    "lint": "next lint"
  },
  "content": "A very super long content line to show whether overflow-x-auto works inside pre code blocks and hello world blah some other text"
}

These scripts refer to the different stages of developing an application:

• dev - Runs next dev to start Next.js in development mode
• build - Runs next build to build the application for production usage
• start - Runs next start to start a Next.js production server
• lint - Runs next lint to set up Next.js' built-in ESLint configuration

Create two directories pages and public at the root of your application:

• pages - Associated with a route based on their file name. For example pages/about.js is mapped to /about
• public - Stores static assets such as images, fonts, etc. Files inside public directory can then be referenced by your code starting from the base URL (/).

Next.js is built around the concept of pages. A page is a React Component exported from a .js, .jsx, .ts, or .tsx file in the pages directory. You can even add dynamic route parameters with the filename.

Inside the pages directory add the index.js file to get started. This is the page that is rendered when the user visits the root of your application

Populate pages/index.js with the following contents:

function HomePage() {
  return <div>Welcome to Next.js!</div>;
}
export default HomePage;

After the set up is complete:

• Run npm run dev or yarn dev or pnpm dev to start the development server on http://localhost:3000
• Visit http://localhost:3000 to view your application
• Edit pages/index.js and see the updated result in your browser

So far, we get:

• Automatic compilation and bundling
• React Fast Refresh
• Static generation and server-side rendering of pages/
• Static file serving through public/ which is mapped to the base URL (/)

In addition, any Next.js application is ready for production from the start. Read more in our Deployment documentation.
