Commands

Nuxi is the new CLI experience for Nuxt 3

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

Since Nuxt 3 becomes a dev dependency thanks to the new Nitro server, you only need to add two commands in your package.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

yarn dev

npm run dev

::

To start Nuxt in development mode with HTTPS https://localhost:3000 (self-signed certificate):

::code-group

yarn dev --https

npm run dev -- --https

:: ::alert options.server from nuxt.config is not supported. You can use --port, --host, --https, --ssl-cert and --ssl-key instead. ::

Building for production

To build your Nuxt application for production, run:

::code-group

yarn build

npm run build

::

Nuxt will create a .output directory with all your application, server and dependencies ready to be deployed. Check out the deployment section to learn where and how you can deploy a Nuxt application using Nitro.

Previewing your production build

Once you've built your Nuxt application, you can preview it locally:

npx nuxi preview

If you're using a supported preset, this will start a local server (for testing purposes only).

Upgrade Nuxt3 version

To upgrade Nuxt3 version:

npx nuxi upgrade

Checking types

To type-check your application, you can use nuxi typecheck. This uses vue-tsc under the hood. If you have both a locally installed version of typescript and vue-tsc, nuxi will use these when type-checking.

npx nuxi typecheck
