Access slotProps in script setup

[fabianwohlfart]

Like here https://vuejs.org/guide/components/slots.html#scoped-slots

<!-- <MyComponent> template -->
<div>
  <slot :text="greetingMessage" :count="1"></slot>
</div>

<MyComponent v-slot="slotProps">
  {{ slotProps.text }} {{ slotProps.count }}
</MyComponent>

is it possible to access the slotProps in the <script setup>?
Like so

<template>
  <MyComponent v-slot="slotProps">
    {{ slotProps.text }} {{ slotProps.count }}
  </MyComponent>
<template>

<script setup>
const slotProps = useSomething()
</script>

?

<script lang="ts" setup>
function foo({ text, count }) {
  return `${text} ${count}`;
}
</script>

<template>
  <MyComponent v-slot="slotProps">
    {{ foo(slotProps) }}
  </MyComponent>
<template>

Great. Thanks for the answer. Is a function the only way to access the data, or is there also another solution to access the slotProps directly in the root of the setup?

You can only access slot props inside the slot, it is a part of the component encapsulation. Though the foo here is inside the script, it's still a part of the rendering logic. If you want to share a component's internal state with its parent, a better way is to use emit.

@fabianwohlfart think about it this way. Nothing is stopping you from including your <MyComponent> multiple times, and each instance would have its own version of "slotProps", so accessing this "simply" inside the setup script doesn't make sense, unless you were to get this only in the context of a specific <MyComponent> instance. You may be able to reference a specific instance of a component via <MyComponent ref="someName"> and then const someName = ref( null ) in your setup script, then dig within that and you'll probably find what you're looking for -- but that's usually not worth the complexity, IMO, and then you're entangling components in the wrong direction, and probably relying dangerously on Vue internal structures. If you're going down that route, use composables instead.
