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 :3000/.

Try to check if you are in client side before accessing to 'window' object, you can use :

if (process.client) {
      console.log(window.location.href)
}

Try to use this:

this.$route.query

In Nuxt 3 you can use the posable useRequestURL() to get the current URL on both server and client (may not work if using hybrid rendering):

const url = useRequestURL();
console.log(url.href);
