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