Vue Tip: Dynamic Slot Names

Vue Tip: Dynamic Slot Names Image

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:

Child.vue
1<script setup lang="ts">
2defineProps<{ items: Array<{ id: string; name: string }> }>();
3</script>
4
5<template>
6  <div v-for="item in items" :key="item.id">
7    ๐Ÿ‘‹
8    <slot :name="item.name" />
9  </div>
10</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:

Parent.vue
1<script setup lang="ts">
2import Child from './components/Child.vue';
3
4const items: Array<{ id: string; name: string }> = [
5  { id: 1, name: 'Item 1' },
6  { id: 2, name: 'Item 2' },
7];
8</script>
9
10<template>
11  <Child :items="items">
12    <template v-for="item in items" v-slot:[item.name]>
13      <p>Hello from {{ item.name }}</p>
14    </template>
15  </Child>
16</template>

Instead of v-slot:[item.name] you can also use #[item.name] shorthand.
