Automatic Setup

We recommend creating a new Next.js app using create-next-app, which sets up everything automatically for you. (You don't need to create an empty directory. create-next-app will make one 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.
