# Commands

Nuxi is the new CLI experience for Nuxt 3

Nuxt 3 has two main commands, one to start development server and one to make production assets.

Since Nuxt 3 becomes a dev dependency thanks to the new [Nitro server](/concepts/server-engine), you only need to add two commands in your `package.json`:

```json
"scripts": {
  "dev": "nuxi dev",
  "build": "nuxi build",
}
```

Then, you can run each command using `npm run <command>` or `yarn <command>`.

## Development Server

To start Nuxt in development mode with hot module replacement on http://localhost:3000:

::code-group
```bash[Yarn]
yarn dev
```
```bash[NPM]
npm run dev
```
::

## Building for production

To build your Nuxt application for production, run:

::code-group
```bash[Yarn]
yarn build
```
```bash[NPM]
npm run build
```
::

Nuxt will create a [`.output`](/docs/directory-structure/output) directory with all your application, server and dependencies ready to be deployed. Checkout the [deployment](/docs/deployment) section to learn where and how you can deploy a Nuxt application using Nitro.
