I'm trying to let players join a game via QR Code. Since that game will be hosted on several IP's, i want to dynamically generate the URL.

This is my current workaround in my NuxtJS Vue Component:

<template>
  <input placeholder="copy browser window url into this field" v-model="fullPath" @change="generateQR">
</template>

<script setup>
  const fullPath = ref(null)
  QRCode.toDataURL(fullPath.value + ...
</script>

What I want to do is something like:

<script setup>
  // not working phantasy code
  QRCode.toDataURL(window.location.href + ...
</script>

When using useRouter() and useRoute()'s .fullPath attribute, I still only get the relative path / instead of http://10.16.1.173:3000/.
