How to load dynamic images from url in Nuxt3?

Question

I have a nuxt 3 component that cannot load a dynamic image that I get from a specific URL (auth0 image).

My template looks like this:

<template>
     <img class="h-28 w-28 rounded-full border-4 border-black bg-gray-300" :src="image" alt=" " />
     <p> {{{name}} {{image}} </p>
</template>

My script is set up as follows:

<script setup>
  import { useAuth0 } from '@auth0/auth0-vue';
  
  let auth0 = process.client ? useAuth0() : undefined;
  let name = ref('');
  let image = ref('');

  //check user authentication state and set name and image
  if(auth0?.isAuthenticated){
    name.value = auth0?.user.value.nickname; //image url: https://....
    image.value = auth0?.user?.value.picture;
  }
</script>

The name and image appear in the paragraph, but the image url does not exist in the src attribute, so the image does not appear. When I go back and type something in VSCode, the image actually renders. Any idea how to render an image?

Answer 1

It should be defined as a computed property because it depends on the value of another property (do the same for name):

<script setup>

  import { useAuth0 } from '@auth0/auth0-vue';
  
  let auth0 = process.client ? useAuth0() : undefined;

  const name = computed(()=>auth0?.isAuthenticated ? auth0?.user?.value.nickname:'');
  const image = computed(()=>auth0?.isAuthenticated ? auth0?.user?.value.picture:'');


</script>
