Having problems with template refs staying null when using TypeScript in Nuxt3?

My Images.vue parent component contains 3 child components: ImagesGridArea1, ImagesGridArea2, and ImagesGridArea3. The children are tagged like this:

<ImagesGridArea1 ref="ref1" :key="ref1key" ... />
. In the parent script, I have: const ref1 = ref(null);. Nothing out of the ordinary.

The issue arises when I use v-if to load only the necessary child component. While refs work fine in Javascript, only the first ref (for the default child component) works in TypeScript. ref2 and ref3 remain null.

Of course, they work if I switch to using v-show, at least with a function ref like this:

<ImagesGridArea2 :ref="(el) => {ref2=el as ComponentPublicInstance}" :key="ref2key" ... />
. However, I would prefer to keep them unmounted when not in use.

Is there a way to obtain instance refs of children without having to keep them mounted using v-if?

Answer №1

Success! I managed to resolve the issue by implementing a <module> element with reference. The mystery remains as to why it functioned correctly with JavaScript before.
