Utilizing Vue3's Ref feature within a component?

Question

Utilizing Vue3's Ref feature within a component?

Currently, I am developing an input component for my login form to avoid creating the input tag repeatedly whenever it is needed. In my previous implementations without components, I was able to save the input value at the @input event using refs (by accessing ref.value.value).

However, I have encountered an issue now that I can't simply add a ref to my input as they are components, not HTML tags. How can I resolve this? :( I require their value for regExp test

Shown below are images of the input before and after:

One way to approach this is by using Vue3 Composition API with script setup:

Take a look at the live playground I've created here!

Here is the parent component code:

<template>
<Comp v-model="myData.field" />

<br />
  
{{ myData.field }}
</template>

<script setup>
import { ref } from 'vue'
import Comp from './Comp.vue'

const myData = ref({
  field: 'something',
})
</script>

And here is the custom input child component code:

<template>
<input
  type="text"
  @input="$emit('update:modelValue', $event.target.value)"
  :value="modelValue"
/>
</template>

<script setup>
defineProps(['modelValue'])
defineEmits(['update:modelValue'])
</script>
