What are some of the potential drawbacks of utilizing the same template ref values repeatedly in Vue 3?

Is it problematic to have duplicate template ref values, such as ref="foo", for the same type but different instances of a component across views in a Vue 3 application? Let's consider the following example pseudocode:

// ROUTE A
<template>
  <MyTableComponent ref="foo" class="stylesForTable_ViewA"/>
</template>

<script setup>
  import { ref } from "vue";
  const foo = ref();
</script>

// ROUTE B (Will not be mounted simultaneously with View A)
<template>
  <MyTableComponent ref="foo" class="stylesForTable_ViewB"/>
</template>

<script setup>
  import { ref } from "vue";
  const foo = ref();
</script>

When transitioning from View A to View B, will Vue's reactivity system detect the identical component type with the same ref value and try to reuse the component instance from View A to construct View B?

Answer №1

When transitioning from View X to View Y, does Vue's reactivity system recognize identical component types with matching ref values and attempt to reuse the component instance from View X in constructing View Y?

No, template refs are not shared across instances of the same component or between different components. A new template ref (e.g., bar) is generated for each individual component instance, distinct for both View X and View Y.
