In Vue JS, how to pass a component as a prop (or a slot) of another component, while been able to set it's own props from a grandchild component ?
Parent :
<template>
<Child>
<SomeComponent />
</Child>
</template>
Child :
<template>
<GrandChild>
<slot></slot>
</GrandChild>
</template>
Grandchild :
<template>
<slot :content="content"></slot> //Setting the props of <SomeComponent/> here
</template>
Use "v-slot:default"!
Parent :
<template>
<Child>
<template v-slot:default="slotProps">
<SomeComponent :content="slotProps.content"/>
</template>
</Child>
</template>
Child :
<template>
<GrandChild>
<template v-slot:default="slotProps">
<slot :content="slotProps.content"></slot>
</template>
</GrandChild>
</template>
Grandchild :
<template>
<slot :content="content"></slot>
</template>
I recommend you refer to this document.

How can I render the header slot to the table component from the child component? This code is not working:
Table component
<template>
<div>
<slot name="header"></slot>
</div>
</template>
Parent component
<template>
<div>
<component :is="currentComponent" > </component>
</div>
</template>
<script>
export default {
data() {
return {
currentComponent: 'Table'
};
},
};
</script>
Child component
<template>
<div>
<parent-component>
<template slot="header">
<h1>test</h1>
</template>
</parent-component>
</div>
</template>
Tried the code above but it dosent work
Expecting to render title from child component
Solution:
Table component
<template>
<div>
<slot name="header"></slot>
</div>
</template>
Parent component
**<template>
<div>
<component :is="currentComponent" >
<template v-for="(_, name) in $slots" #[name]="slotData">
<slot :name="name" v-bind="slotData || {}" />
</template>
</component>
</div>
</template>**
<script>
export default {
data() {
return {
currentComponent: 'Table'
};
},
};
</script>
Child component
<template>
<div>
<parent-component>
<template slot="header">
<h1>test</h1>
</template>
</parent-component>
</div>
</template>
Given the following "wrapper component" DefaultButton for a Quasar QBtn, I make use of v-bind="$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>

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>
