Apart from structured and formatted text, rich text elements can also contain references to content components and content items, and links to content items.Let’s see how to deal with these references so your rich text is displayed correctly.
How structured rich text helps you
One of the benefits of using an API-first CMS like Kontent.ai is that you’re able to clearly structure your content so it can be used in any channel. But you don’t want to be restricted to needing to know exactly what content will be included ahead of time.Structure is great, but your content creators want the freedom to add various amounts of various kinds of content. For this, you can add structure to your rich text with content components and linked items.The major difference between content components and linked items is that components exist only inside a single content item, while linked items can be reused across your project. You can read more about when to use components and when linked items.With Kontent.ai, you can link content items together in two ways:
In a rich text element – here, your items are included within the text, which requires additional work from your app to render them. This way is covered here.
This article will look at how to add structure to your rich text through examples of components. For your rich text, the principle is the same for components and linked items. The items and components can be distinguished in the JSON response, but it's not necessary for these purposes.There are two ways to implement the structure on your front end:
Defining resolvers for content types that might appear in the rich text.
Using templates or specific views for structured blocks.
With most technologies, you can choose whether to take a global approach with resolvers or iterate over blocks, such as by making use of design templates for blocks within your app.Choosing to use a structured model can help ensure you don’t need to know what type of content is being added to your rich text, as your hierarchy will be created automatically.
Resolve items and components in rich text
This example shows how to resolve embedded content in articles. The tweets can be inserted either as components or content items. You can use this approach for any other type of structured content in your rich text elements.If you don’t adjust your application, any content item or component inserted in rich text elements resolves to an empty object reference, which won’t be rendered on the page.
For the final HTML, you could also work with embedded tweets, such as by calling the Twitter API.
Resolve hyperlinks to content items
This example will show you how to resolve links to content item used within the body of articles. Without adjusting your application, any link in a rich text element that points to a content item will contain an empty value. Let’s see how to resolve such links correctly.
The URL to a content item linked in the rich text element is now correctly resolved.
Resolve linked content
When your content creators build pages by linking content items together, your app needs to know how to get all these individual items and resolve them.
