Can not host nuxt app in local network

Hey, I am trying to host my nuxt app in my local network to test it on mobile devices. I run npm run dev -- --host. Nuxt acts like the --host argument is not there. I do not get the QR-Code like usual and it still tells me "use --host to expose"

Hi @Leander. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- Based on the information provided in the knowledge sources, I can offer some guidance on hosting your Nuxt app on your local network. It seems there might be a configuration issue preventing the --host flag from working as expected. Here are a few things you can try: 1. Explicitly set the host in your nuxt.config.js or nuxt.config.ts file:

export default defineNuxtConfig({
  devServer: {
    port: 3000,     
    host: '0.0.0.0' // do not put localhost (only accessible from the host machine)
  }
})

export default defineNuxtConfig({
  devServer: {
    port: 3000,     
    host: '0.0.0.0' // do not put localhost (only accessible from the host machine)
  }
})

This configuration should allow your app to be accessible from other devices on your local network, as mentioned in the Stack Overflow post. 2. If you're using environment variables, you can set the HOST variable:

HOST=0.0.0.0 npm run dev

HOST=0.0.0.0 npm run dev

3. Make sure you're using the correct command. The --host flag should be passed to the nuxi dev command, not directly to npm run dev. You might want to modify your package.json script to include this flag:

"scripts": {
  "dev": "nuxi dev --host"
}

"scripts": {
  "dev": "nuxi dev --host"
}

Then you can simply run npm run dev. 4. If you're still having issues, you might want to check if there are any firewall or network settings blocking the connection. If none of these solutions work, it's possible that there might be an issue with your specific Nuxt version or setup. In that case, you might want to check for any reported issues on the Nuxt GitHub repository or consider updating to the latest version if you haven't already. Remember, when your app is successfully exposed to the network, you should see a Network URL in the console output, which you can use to access your app from other devices on the same network. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

Let me check the knowledge base for you again. One moment! :books: ---------------------- I understand your concern about having to change the configuration every time you want to switch between hosting on your local network and normal mode. Fortunately, there's a more flexible solution that doesn't require modifying your nuxt.config.ts file each time. You can use environment variables to dynamically set the host and port. Here's how you can set it up: 1. Update your nuxt.config.ts file to use environment variables:

export default defineNuxtConfig({
  devServer: {
    port: process.env.PORT || 3000,
    host: process.env.HOST || 'localhost'
  }
})

export default defineNuxtConfig({
  devServer: {
    port: process.env.PORT || 3000,
    host: process.env.HOST || 'localhost'
  }
})

2. Then, you can modify your package.json scripts to include both options:

{
  "scripts": {
    "dev": "nuxt dev",
    "dev:host": "HOST=0.0.0.0 nuxt dev"
  }
}

{
  "scripts": {
    "dev": "nuxt dev",
    "dev:host": "HOST=0.0.0.0 nuxt dev"
  }
}

Now you have two commands: - Use npm run dev for normal mode (localhost only) - Use npm run dev:host to expose your app on your local network This approach allows you to easily switch between the two modes without changing your configuration file. When you run npm run dev:host, it will set the HOST environment variable to 0.0.0.0, which makes your app accessible on your local network. This solution is based on the information from the Nuxt documentation on the devServer configuration and the Stack Overflow post about Dockerized nginx and vue+nuxt. By using this method, you can maintain flexibility in your development process without the need to constantly modify your configuration files. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

seems to work fine for me

danielroe•2w ago

(same with npm run dev -- --host) note that changes in vite + nuxt for security mean you will probably need to specify an ip address or hostname (e.g. --host 192.168.0.1) to allow connection to your vite dev server

(or add it to vite.server.allowedHosts): https://vite.dev/config/server-options.html#server-allowedhosts

(the next version of nuxi will automatically add it to allowedHosts if you pass it via --host)
