Check if named slot exists in your page with Vue.js

In the Composition API we have the runtime function useSlots() that can be used to check if our slot exist or not, to do that we need to import it from Vue and check the existence of slot directly in template.

<template>
    <div>
        <nav
            v-if="slots.myNamedSlot"
        >
            <slot name="myNamedSlot" />
        </nav>
    </div>
</template>

<script setup>
import { useSlots } from 'vue'

// this const will be avaiable on template
const slots = useSlots()
</script>

<style>
</style>

Attention: slots elements are dynamic and not reactive, so we need to check them directly in template.

That's it!

See'ya!
