How to target elements inside <script setup> of Vue 3 component?

How can I target the element with test class inside this vue component:

<template>
  <div id="test" class="test">

  </div>
</template>


<script setup>

console.log(document.querySelector('.test'))
</script>

This component is imported into another component. The console outputs null.

the component is not rendered before that script is run

You want to wait until it is mounted

<template>
  <div id="test" class="test">

  </div>
</template>


<script setup>

import { onMounted } from 'vue'; 
onMounted(() => { 
    console.log(document.querySelector('.test')) 
});
</script>

In general, there's hardly ever any need to use DOM methods like that in vue though - I won't say never, because I know as soon as I say that, someone will come up with a valid reason to

I never have though
