First you need to ensure that your device is in same network

inpackage.json file in your app, add this command

"host": "vite --host" or use your own name, im usinghost for command name. you can change the setting insidevite.config.js too with this setting

  server: {    host: true  }

vite will automatically use your ip as a server ip, then run the command withnpm run host, and finally you can access your app in external device, just access it with{your ip}:{your app port} eg:192.168.10.1:3000.
