`--logLevel=<silent\|info\|verbose>` |  | Specify build-time log level

`--envName` |  | The environment to use when resolving configuration overrides (default is `production` when building, and `development` when running the dev server)
`--no-clear` |  | Disable clear console on restart
`--no-fork` |  | Disable forked mode

`-o, --open` | `false` | Open the URL in the browser
`--https` |  | Enable HTTPS
`--publicURL` |  | Displayed public URL (used for QR code)

<!--/dev-opts-->

The port and host can also be set via NUXT_PORT, PORT, NUXT_HOST or HOST environment variables.

Additionally to the above options, `nuxi` can pass options through to `listhen`, e.g. `--no-qr` to turn off the dev server QR code. You can find the list of `listhen` options in the [unjs/listhen](https://github.com/unjs/listhen) docs.

This command sets `process.env.NODE_ENV` to `development`.

If you are using a self-signed certificate in development, you will need to set `NODE_TLS_REJECT_UNAUTHORIZED=0` in your environment.
