In this Vue tip, I want to show you how to use dynamic slot names in Vue.
This can be useful for scenarios like a multi-step form or a table component.
Let's take a look at how you can dynamically generate slots at runtime:
<script setup lang="ts">
defineProps<{ items: Array<{ id: string; name: string }> }>();
</script>
<template>
<div v-for="item in items" :key="item.id">
👋
<slot :name="item.name" />
</div>
</template>
In your parent component you can now use the v-slot:[item.name] syntax to dynamically generate a slot name for each item in the items array:
<script setup lang="ts">
import Child from './components/Child.vue';
const items: Array<{ id: string; name: string }> = [
{ id: 1, name: 'Item 1' },
{ id: 2, name: 'Item 2' },
];
</script>
<template>
<Child :items="items">
<template v-for="item in items" v-slot:[item.name]>
<p>Hello from {{ item.name }}</p>
</template>
</Child>
</template>
Instead of v-slot:[item.name] you can also use #[item.name] shorthand.
