Question

Implementing Vue components dynamically within a v-for loop based on specific conditions

My JS array is structured like this:

[{type:'text', data: 'some text'},{type: 'image',  data: 'link/to/image'}]

Each value of type corresponds to a different Vue component (<text-block>, <image-block>). I want to use a v-for loop to iterate over this array and dynamically create the appropriate Vue component based on the type.

Most examples of v-for demonstrate creating multiple instances of the same element, such as multiple <li> elements. Is there a method to generate different elements within a v-for loop?

Answer №1

If you want to conditionally render elements, you can simply use the v-if directive:

<div v-for="(item, i) in items" :key="i">
    <text-element v-if="item.type === 'text'"></text-element>
    <image-element v-if="item.type === 'image'"></image-element>
</div>

Another way to achieve the same is by using dynamic components:

<div v-for="(item, i) in items" :key="i">
    <dynamic-component :is="item.type + '-element'"></dynamic-component>
</div>

Just make sure to import the components and define them within the instance.
