I am trying to create a wrapper component around an existing component (q-table from the quasar-framework).
<!-- MyTable.vue -->
<template>
<q-table :title="title" ...>
<template v-slot:top="props">
...
</template>
<template v-slot:body="props">
<q-tr :props="props">
...
</q-tr>
</template>
</q-table>
</template>
<template v-slot:body="props"> and <template v-slot:top="props"> are slots of the q-table component.
How to overwrite these slots in the App.vue:
<!-- App.vue -->
<template>
<div>
<my-table>
???
</my-table>
</div>
</template>

I currently do this to enable slots and scoped slots usage.
<template>
<v-text-field
v-bind="computedAttrs"
v-on="$listeners"
>
<!-- Cycling through slots -->
<template v-for="(_, name) in $slots">
<template :slot="name">
<slot :name="name"></slot>
</template>
</template>
<!-- Cycling through scoped slots -->
<template
v-for="(_, name) in $scopedSlots"
#[name]="data"
>
<slot
:name="name"
v-bind="data"
></slot>
</template>
</v-text-field>
</template>
I don't understand why I cannot do this to enable slots usage.
<template>
<v-text-field
v-bind="computedAttrs"
v-on="$listeners"
>
<!-- Cycling through slots -->
<template
v-for="(_, name) in $slots"
#[name]
>
<slot :name="name"></slot>
</template>
<!-- Cycling through scoped slots -->
<template
v-for="(_, name) in $scopedSlots"
#[name]="data"
>
<slot
:name="name"
v-bind="data"
></slot>
</template>
</v-text-field>
</template>
I saw people doing this, but I don't understand why it doesn't work for me. What am I doing wrong?
Note: I'm using Vue2.
Given the following "wrapper component" DefaultButton for a Quasar QBtn, I make use of v-bind="$attrs" and a v-for loop for passing down the slots.
DefaultButton.vue
<template>
<q-btn v-bind="$attrs" color="primary" outline rounded>
<template v-for="(_, slot) in $slots" #[slot]="scope">
<slot :name="slot" v-bind="scope || {}" />
</template>
</q-btn>
</template>
<script setup></script>
Now if I'd like to create another wrapper for DefaultButton.vue, is it necessary to repeat inserting v-bind="$attrs" and the slot template?
SomeIconButton.vue
<template>
// Is this sufficient?
<default-btn icon="some-icon"></default-btn>
// Or is this required?
<default-btn v-bind="$attrs" icon="some-icon">
<template v-for="(_, slot) in $slots" #[slot]="scope">
<slot :name="slot" v-bind="scope || {}" />
</template>
</default-btn>
</template>
<script setup />
</script>
I am currently using a simple implementation of slots in Vue 2. I have my parent component using MyComponent and slotting in OtherComponent. My MyComponent code
uses <slot></slot> for the content. How would I make changes to the slots to adapt for Vue 3's v-slot since slot is deprecated?
Parent.vue
<MyComponent>
<template v-slot="slotProps">
<OtherComponent
:data="slotProps.data"
>
</OtherComponent>
</template>
</MyComponent>
MyComponent.vue
<template>
<div class="container">
<template v-for="(item, index) in data">
<slot :item="item"></slot>
</template>
</div>
</template>
Passing a header component as a named slot into router-view. But router-view not exactly displaying it. Normally this was work in vue 2. But it's not with vue 3. Is the way doing it changed or is it impossible to do it now?
header component
<template>
<header id="g-header">
<figure>
<img id="logo"
src="#/assets/images/logo.jpg"
alt="The beautiful MDN logo.">
</figure>
<nav id="g-nav" class="flex justify-space-between">
<a v-for="(link, idx) in links" :key="idx"
class="flex justify-center align-center capitalize"
:href="link.val">{{ link.text }}</a>
</nav>
</header>
</template>
router-view component
<template>
<div id="moduleA" class="modules">
<router-view class="moduleA-children">
<template #header>
<app-header></app-header>
</template>
</router-view>
</div>
</template>
children view component
<template>
<div id="step1">
<slot name="header"></slot>
<div class="row">the named slot OR default slot not showing</div>
</div>
</template>
Is there a way to accomplish this? Or do I missing something here?
In Vue Router 4, <router-view> exposes the component to render as a v-slot prop, named Component, which would be used with the built-in <component> tag. You could pass any slots to the component within that <component> tag:
<router-view v-slot="{ Component }">
<component :is="Component">
<template #header>
<app-header></app-header>
</template>
</component>
</router-view>

Lets say, I have the following vuejs structure:
<!-- MainComponent.vue -->
<template>
<childcomponent></childcomponent>
</template>
<!-- ChildComponent.vue -->
<template>
<div>
<grandchild></grandchild>
</div>
</template>
<!-- GrandchildComponent.vue -->
<template>
<div>
FooBar
<slot name="actions"></slot>
</div>
</template>
If I want to set a value for the grandchild-slot "actions" in the child-component, I have to do this:
<!-- ChildComponent.vue -->
<template>
<div>
<grandchild>
<template slot="actions">Actions from ChildComponent</template>
</grandchild>
</div>
</template>
But how to bypass "actions" from the MainComponent? I tried this, but thats not working:
<!-- MainComponent.vue -->
<template>
<childcomponent>
<template slot="actions" slot-scope="props">
Actions from MainComponent
</template>
</childcomponent>
</template>
<!-- ChildComponent.vue -->
<template>
<div>
<grandchild>
<slot name="actions">
<template slot="actions" slot-scope="props">
Actions from ChildComponent
</template>
</slot>
</grandchild>
</div>
</template>
After a lot of research, I think the only possible way of doing it, is only over the render function (https://v2.vuejs.org/v2/guide/render-function.html).
The main idea behind it is to write instead of html templates for ChildComponent.vue and GrandchildComponent.vue custom render functions.
