Vue3 Reactivity in script setup for translation - vue.js

I am adding some DOM elements in the script setup side but I want the messages to change when I change the language. I am using vue-i18n plugin. It's easy to do it in the template section because I can basically use the useI18n().t method but how can I do this in the script setup section. Using the useI18n().t method doesn't ensure reactivity.
Example Code:
$(".time")[0].innerHTML = `
<div>0<span>${useI18n().t("details.hour")}</span></div>
<div>0<span>${useI18n().t("details.minute")}</span></div>
<div>0<span>${useI18n().t("details.second")}</span></div>
`

Manipulating DOM directly inside the script leads to inconsistence in your app, you should drive your component by different reactive data to achieve your goal.
In your current situation try to define a computed property based on the translation then render it inside the template based on its different properties :
<script setup>
const {t} =useI18n()
const time = computed(()=>{
return {
hour:t(""details.hour"),
minute:t(""details.minute"),
second:t(""details.second"),
}
})
</script>
<template>
<div class="time">
<div>0<span>{{time.hour}}</span></div>
<div>0<span>{{time.minute}}</span></div>
<div>0<span>{{time.second}}</span></div>
</div>
</template>

Child components not rendering when referenced dynamically in composition API

I'm converting some components from vue 3's option API to the composition API. In this particular component I have two nested child components:
<script lang="ts" setup>
import ShiftOperation from "#/components/transformation-widgets/ShiftOperation.vue";
import RawJolt from "#/components/transformation-widgets/RawJolt.vue";
console.log([ShiftOperation, RawJolt])
...
From what I understand, if you're using the setup attribute in the script tag then all you have to do is import the component into a variable like I'm doing above and it should be available for the template without having to do anything else, like it's not like the old options api where you had to inject those components into the parent component.
Both components are imported successfully (confirmed by the console log:
When I'm rendering out this parent component I'm using the two child components to render out an array of data where I reference the children dynamically in the template based on information in each block of data that I'm iterating over:
<template>
<div class="renderer-wrapper">
<component
v-for="(block, index) in store.specBlocks"
v-bind:key="index"
:block="block"
:index="index"
:is="determineBlockComponent(block)"
#block-operation-updated="updateBlock"
>
</component>
</div>
</template>
// logic for determining the component to use:
export const determineBlockComponent = (block: JoltOperation) => {
switch (block.renderComponent) {
case 'shift':
return 'ShiftOperation'
default:
return 'RawJolt'
}
}
This worked fine in the options api version of it, but for some reason the components don't actually render. They show up in the elements tab:
But they don't show up in the view. I also added a created lifecycle hook into the child components that just console.log's out saying "created X", but those hooks don't fire.
Business logic wise nothing has changed, it's just been going from option api to composition api, so I'm assuming I'm missing some key detail.
Any ideas?
Your determineBlockComponent function should not return the string but the object of the component. Replace return 'ShiftOperation' with return ShiftOperation

Is Tailwind class binding possible through Storyblok?

I'm trying to develop some components that will be used by our content editors in Storyblok and there's a use case where we would like to define layout properties (using Tailwind's classes) through props that will be coming from Storyblok components.
As an example,
I am passing the width prop through storyblok giving a value of w-1/2 which is a Tailwind class. As you see on the right the class is applied just fine to the element but there's no actual impact on the page. I have tried the same with many other classes (either for background or border colors or for text styling etc, tried to use Tailwind classes as props coming from Storyblok but didn't work).
My only guess is that Nuxt is a server side application and the CSS gets compiled on build time, therefore any new class binding to the DOM will not reflect the actual CSS that they represent. Is this right? If yes, is there a way to make this happen and work?
The code for the widthSetter component is as simple as that
<template>
{{blok.width}}
<div v-editable="blok" :class="[ blok.width ]">
<component
v-for="value in blok.blocks"
:key="value._uid"
:is="value.component"
:blok="value"
/>
</div>
</template>
<script lang="ts" setup>
const props = defineProps({
blok: {
type: Object,
required: true,
},
})
</script>
You need to add Complete Class Names.
As there is no w-1/2 in your code, TW won't generate the class.
You can workaround the issue by adding the class to safelist.
Doc: https://tailwindcss.com/docs/content-configuration#safelisting-classes
module.exports = {
safelist: ['w-1/2'],
//...
}
Then w-1/2 utility will be generated regardless if it shows up in your code or not.

Find nearest parent Vue component of template ref (Vue 3)

When a Vue template ref is mounted, I want to get the nearest parent Vue component. This should be generic and work for any template ref so I've put it in a composition function (but that's just an implementation detail).
I had this working but my implementation used elem.__vueParentComponent while iteratively searching an element's ancestors. While reading the Vue source code I saw __vueParentComponent was only enabled for dev mode or if dev tools is enabled in production. Thus, I don't want to rely on that flag being enabled.
I thought this might be possible using vnodes but this isn't easily google-able. Here's an example of what I'm trying to do:
function useNearestParentInstance(templateRef) {
function getNearestParentInstance(el) {
// code here
}
onMounted(() => {
const el = templateRef.value;
const instance = getNearestParentInstance(el);
// do something with instance
});
}
<template>
<div>
<SomeComponent>
<div>
<div ref="myElem"></div>
</div>
</SomeComponent>
</div>
</template>
<script>
export default {
setup() {
const myElem = ref();
// nearest would be SomeComponent's instance in this case
useNearestParentInstance(myElem);
...
}
}
</script>
If you want the nearest vue parent you can simply use
ref().$parent // Not sure if syntax is same in vue3
ref().$parent will get the first vuecomponent that is the parent of the ref that you placed.

Generate Vue Component with vanilla JS

I am currently using the bootstrap table component to display a list (bootstrap-table.com)
This component (or jQuery plugin wrapped within a vue component) has a formatter for each column.
example with source code: https://examples.bootstrap-table.com/#welcomes/vue-component.html#view-source
I need to build a more complex set of links which involve some js processing that could easily be done with vue.
Instead of the formatter returning the <a> tag I would like to return the contents of a <component>. I have tried this but haven't been able to render a component.
I'm almost sure this is impossible because the child component is not previously binded which means the component won't be "reactive".
As an alternative I can build a js function that generates all the required links.
Another phrasing for this question would be: Is there any possibility to generate a vue component from vanilla js?
The above was not possible the way was tried because the components cannot be simply rendered like html tags as they can have methods and computed data therefore they must be compiled.
It looks like the solution for the above situation is using the Vue.compile() method:
const template = `
<ul>
<li v-for="item in items">
{{ item }}
</li>
</ul>`;
const compiledTemplate = Vue.compile(template);
new Vue({
el: '#app',
data() {
return {
items: ['Item1', 'Item2']
}
},
render(createElement) {
return compiledTemplate.render.call(this, createElement);
}
});

Can I get Vue.js component as an instance?

I try to get the template of Vue.js component since I need it for another function.
First,
I have a function that needs a Vue.js component template because I want the data in the template to dynamically change and not just some static HTML.
Secondly,
I have a problem to get a template from Vue.js component. Maybe they are not allowed to do that but I am not sure. I am new to Vue.js.
But from my understanding of JS, maybe this can happen.
I am tried to do something like this:
let vmComponent = Vue.component('VueComponent', {
data() {
return {
title: 'I am a Vue.js component manually.'
}
},
template: `
<div>
<h2>Template Exchange</h2>
<h3>{{ title }}</h3>
</div>`,
});
console.log(vmComponent.template);
I hope to get the HTML string when I run vmComponent.template
If this way of doing things is not possible. Is there any other ways I can get Vue.js component template as HTML String.
For example, maybe in a new.Vue({})
It's possible to access component template with vmComponent.options.template.
A template can be declared as a string for reuse:
export const template = `...`;
const vmComponent = Vue.component('VueComponent', {
template,
...
});
This may not work with pre-compiled templates.
