Create a new Next.js app and run it locally.

Quick start

1. Create a new Next.js app named my-app
2. cd my-app and start the dev server.
3. Visit http://localhost:3000.

pnpm create next-app@latest my-app --yes
cd my-app
pnpm dev

npx create-next-app@latest my-app --yes
cd my-app
npm run dev

yarn create next-app@latest my-app --yes
cd my-app
yarn dev

bun create next-app@latest my-app --yes
cd my-app
bun dev

• --yes skips prompts using saved preferences or defaults. The default setup enables TypeScript, Tailwind CSS, ESLint, App Router, and Turbopack, with import alias @/*, and includes AGENTS.md (with a CLAUDE.md that references it) to guide coding agents to write up-to-date Next.js code.

System requirements

Before you begin, make sure your development environment meets the following requirements:

• Minimum Node.js version: 20.9
• Operating systems: macOS, Windows (including WSL), and Linux.

Supported browsers

Next.js supports modern browsers with zero configuration.

• Chrome 111+
• Edge 111+
• Firefox 111+
• Safari 16.4+

Learn more about browser support, including how to configure polyfills and target specific browsers.

Create with the CLI

The quickest way to create a new Next.js app is using create-next-app, which sets up everything automatically for you. To create a project, run:

pnpm create next-app

npx create-next-app@latest

yarn create next-app

bun create next-app

On installation, you'll see the following prompts:

What is your project named? my-app
Would you like to use the recommended Next.js defaults?
    Yes, use recommended defaults - TypeScript, ESLint, Tailwind CSS, App Router, AGENTS.md
    No, reuse previous settings
    No, customize settings - Choose your own preferences

If you choose to customize settings, you'll see the following prompts:

Would you like to use TypeScript? No / Yes
Which linter would you like to use? ESLint / Biome / None
Would you like to use React Compiler? No / Yes
Would you like to use Tailwind CSS? No / Yes
Would you like your code inside a `src/` directory? No / Yes
Would you like to use App Router? (recommended) No / Yes
Would you like to customize the import alias (`@/*` by default)? No / Yes
What import alias would you like configured? @/*
Would you like to include AGENTS.md to guide coding agents to write up-to-date Next.js code? No / Yes

After the prompts, create-next-app will create a folder with your project name and install the required dependencies.

Manual installation

To manually create a new Next.js app, install the required packages:

pnpm i next@latest react@latest react-dom@latest

npm i next@latest react@latest react-dom@latest

yarn add next@latest react@latest react-dom@latest

bun add next@latest react@latest react-dom@latest

Good to know:

• The App Router uses React canary releases built-in, which include all the stable React 19 changes, as well as newer features being validated in frameworks, but you should still declare react and react-dom in package.json for tooling and ecosystem compatibility.
• The Pages Router uses the React version from your package.json.

Then, add the following scripts to your package.json file:

{
  "scripts": {
    "dev": "next dev",
    "build": "next build",
    "start": "next start",
    "lint": "eslint",
    "lint:fix": "eslint --fix"
  }
}

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

• next dev: Starts the development server using Turbopack (default bundler).
• next build: Builds the application for production.
• next start: Starts the production server.
• eslint: Runs ESLint.

Turbopack is now the default bundler. To use Webpack run next dev --webpack or next build --webpack. See the Turbopack docs for configuration details.

Create the app directory

Next.js uses file-system routing, which means the routes in your application are determined by how you structure your files.

Create an app folder. Then, inside app, create a layout.tsx file. This file is the root layout. It's required and must contain the <html> and <body> tags.

export default function RootLayout({
  children,
}: {
  children: React.ReactNode
}) {
  return (
    <html lang="en">
      <body>{children}</body>
    </html>
  )
}

export default function RootLayout({ children }) {
  return (
    <html lang="en">
      <body>{children}</body>
    </html>
  )
}

Create a home page app/page.tsx with some initial content:

export default function Page() {
  return <h1>Hello, Next.js!</h1>
}

export default function Page() {
  return <h1>Hello, Next.js!</h1>
}

Both layout.tsx and page.tsx will be rendered when the user visits the root of your application (/).

Good to know:

• If you forget to create the root layout, Next.js will automatically create this file when running the development server with next dev.
• You can optionally use a src folder in the root of your project to separate your application's code from configuration files.

Create the pages directory

Next.js uses file-system routing, which means the routes in your application are determined by how you structure your files.

Create a pages directory at the root of your project. Then, add an index.tsx file inside your pages folder. This will be your home page (/):

export default function Page() {
  return <h1>Hello, Next.js!</h1>
}

export default function Page() {
  return <h1>Hello, Next.js!</h1>
}

Next, add an _app.tsx file inside pages/ to define the global layout. Learn more about the custom App file.

import type { AppProps } from 'next/app'

export default function App({ Component, pageProps }: AppProps) {
  return <Component {...pageProps} />
}

export default function App({ Component, pageProps }) {
  return <Component {...pageProps} />
}

Finally, add a _document.tsx file inside pages/ to control the initial response from the server. Learn more about the custom Document file.

import { Html, Head, Main, NextScript } from 'next/document'

export default function Document() {
  return (
    <Html>
      <Head />
      <body>
        <Main />
        <NextScript />
      </body>
    </Html>
  )
}

import { Html, Head, Main, NextScript } from 'next/document'

export default function Document() {
  return (
    <Html>
      <Head />
      <body>
        <Main />
        <NextScript />
      </body>
    </Html>
  )
}

Create the public folder (optional)

Create a public folder at the root of your project to store static assets such as images, fonts, etc. Files inside public can then be referenced by your code starting from the base URL (/).

You can then reference these assets using the root path (/). For example, public/profile.png can be referenced as /profile.png:

import Image from 'next/image'

export default function Page() {
  return <Image src="/profile.png" alt="Profile" width={100} height={100} />
}

import Image from 'next/image'

export default function Page() {
  return <Image src="/profile.png" alt="Profile" width={100} height={100} />
}

Run the development server

1. Run npm run dev to start the development server.
2. Visit http://localhost:3000 to view your application.
3. Edit the app/page.tsxpages/index.tsx file and save it to see the updated result in your browser.

Set up TypeScript

Minimum TypeScript version: v5.1.0

Next.js comes with built-in TypeScript support. To add TypeScript to your project, rename a file to .ts / .tsx and run next dev. Next.js will automatically install the necessary dependencies and add a tsconfig.json file with the recommended config options.

IDE Plugin

Next.js includes a custom TypeScript plugin and type checker, which VSCode and other code editors can use for advanced type-checking and auto-completion.

You can enable the plugin in VS Code by:

1. Opening the command palette (Ctrl/⌘ + Shift + P)
2. Searching for "TypeScript: Select TypeScript Version"
3. Selecting "Use Workspace Version"

See the TypeScript reference page for more information.

Set up linting

Next.js supports linting with either ESLint or Biome. Choose a linter and run it directly via package.json scripts.

• Use ESLint (comprehensive rules):

{
  "scripts": {
    "lint": "eslint",
    "lint:fix": "eslint --fix"
  }
}

• Or use Biome (fast linter + formatter):

{
  "scripts": {
    "lint": "biome check",
    "format": "biome format --write"
  }
}

If your project previously used next lint, migrate your scripts to the ESLint CLI with the codemod:

npx @next/codemod@canary next-lint-to-eslint-cli .

If you use ESLint, create an explicit config (recommended eslint.config.mjs). ESLint supports both the legacy .eslintrc.* and the newer eslint.config.mjs formats. See the ESLint API reference for a recommended setup.

Good to know: Starting with Next.js 16, next build no longer runs the linter automatically. Instead, you can run your linter through NPM scripts.

See the ESLint Plugin page for more information.

Set up Absolute Imports and Module Path Aliases

Next.js has in-built support for the "paths" and "baseUrl" options of tsconfig.json and jsconfig.json files.

These options allow you to alias project directories to absolute paths, making it easier and cleaner to import modules. For example:

// Before
import { Button } from '../../../components/button'

// After
import { Button } from '@/components/button'

To configure absolute imports, add the baseUrl configuration option to your tsconfig.json or jsconfig.json file. For example:

{
  "compilerOptions": {
    "baseUrl": "src/"
  }
}

In addition to configuring the baseUrl path, you can use the "paths" option to "alias" module paths.

For example, the following configuration maps @/components/* to components/*:

{
  "compilerOptions": {
    "baseUrl": "src/",
    "paths": {
      "@/styles/*": ["styles/*"],
      "@/components/*": ["components/*"]
    }
  }
}

Each of the "paths" are relative to the baseUrl location.
