A common approach to website development is to build components that can be reused across different web pages. The benefit to this approach is that you end up doing less duplicate work by managing the components rather than managing duplicate content across different pages. Popular JavaScript frameworks like React, Vue and Angular utilize this concept on the application code level to much success. How can we benefit from this approach on the content management level?
In this tutorial I'm going to show you how to build a component-based website using React and the Cosmic CMS. The goal is to save developers and content managers time and provide a scalable content model.
Build the Content Model
* Prereqs: This article assumes you have an understanding of Cosmic concepts: Object Types, Objects and Metafields. If you need to brush up on these concepts, go to the Getting Started guide.
Using Cosmic Object Types and Metafields, we can create composable components that can be used across website pages. For our example we will create three Object Types:
1. Pages
2. Sections (components used in Pages)
3. Team Members (used in the Team Section)
Let's look at each Object Type:
Pages
All Pages will include the following:
1. Title (Text)
2. Content (HTML Textarea)
3. Sections (Multiple Objects Relationship Metafield)
The Multiple Objects Relationship Metafield will be used to manage the Page Sections.
Team Members
Metafields:
1. Name (Text Metafield)
2. Image (File Metafield)
3. Quote (Plain Textarea Metafield)
Sections
The Sections Object Type will be more dynamic and allow for different Metafields.
Team Section
Metafields:
1. Headline
2. Multiple Object Relationship Metafield (Team)
- Name
- Image
- Quote
Add your team members:
Signup Section
Metafields:
1. Headline (Text Metafield)
2. Image (File Metafield)
3. Content (HTML Metafield)
4. CTA (Text Metafield)
Add Sections to Pages
Now that we have our Sections set up, we can add them to our Pages:
Code it up
Now that we have our content saved, let's do some coding. Download the React starter:
git clone https://github.com/cosmicjs/react-starterNow go into the Page component and edit it to look like this:
As you can see, we've added Section List on our Page Object. Our Section List and Section components looks like this:
Output of the Section component is determined by the data passed via the section prop.
In Conclusion
The Cosmic CMS is a great solution for building component-based websites. In our example, we created a Page Object with a Multiple Object Metafield connected to a Sections Object Type to add our Section components. The benefit to this approach is that we can now manage the section content in one place and reuse it across pages without having to go into each page to edit duplicate data.
