How to render dynamic component defined in JSON using Vue.js
Storyblok is the first headless CMS that works for developers & marketers alike.
With Vue.js it is unbelievably easy to render dynamic components, which we can utilize to render content with specific components and layouts by only using their name.
A basic content JSON that should be rendered
The content JSON below contains an array called
body which consists of multiple objects with different fields and one attribute called
component which allows us to determine what component we should use to render its content.
Dynamic components in use
All we have to do to render the above array of objects is to loop through the array itself. Below you can see that we're using a
template tag, even tho it would be possible add it directly to the
component tag itself (I find it a bit more readable for this tutorial).
Looping through the content array
Use dynamic components
Now to actually use the dynamic components we pass the name of the component in the
:is attribute as shown below. To allow the component to access the current instance properties we're using the
block property and pass the current
block object itself. We use
blok in our tutorials as they are not components but instance of component schemas. Since Vue does require a
:key while looping through content we're going to use the property
_uid which can basically be anything but should be unique in your content tree.
Create and include your components
We're using two nested components one is called
foo and the other one is called
Once created you can import the component in your Vue component which contains component approach, or register them globally.
There are only two points different between
bar as one uses the property
headline and the other
title to showcase that the components can be completely different from their structure. They can even contain another content array and use the
component approach in them as well to build a more complex layout.
Editing the JSON
You can now add more components of the type
bar with different
title/headline values and they will be rendered as if you would add them statically under each other. The order in the JSON defines the order of them being rendered.
With Storyblok you're able to build such a structure with reusable and nestable components. Using the
blocks field type you are able to add the exact behavior as you would edit the JSON directly, but in an easy to use interface. After adding the content in the interface you're able to consume our Content Delivery API. You can try it yourself and exchange the static content by loading content from our API.
