🔥 Vue Tip: Dynamic Slot Names

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">

          2 defineProps<{ items: Array<{ id: string; name: string }> }>();

          3 </script>

          4 

          5 <template>

          6   <div v-for="item in items" :key="item.id">

          7     👋

          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">

          2 import Child from './components/Child.vue';

          3 

          4 const 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.
