AEM Headless CMS

Your campaign looks sterling. You’re excited to get it out there. But as your team begins to deploy the content across different websites, mobile apps, and channels, frustration sets in. The hours of tedious re-publishing and updating the same content in multiple CMSs feel endless…

It’s time to permanently fix the process. Consider moving to a headless CMS, where you can create content in one place and have it automatically reused across various digital platforms.

Yet, an idea is only as good as its execution. You need a powerful, reliable, and scalable CMS.

The good news is that the leading CMS on the market, Adobe Experience Manager (AEM), works perfectly as a Headless CMS. Let’s see if that’s the solution you’re looking for.

What a Headless CMS Is

If a content management system separates content creation from content delivery, we can call it Headless. It means that you have a console and a repository built as one part (body). It’s the backend where you create and store content. You can connect this backend to any and many frontends (heads), such as apps or sites, to display the content to users.

Headless content management solutions are also called API-first CMSs. That’s because they connect to the sites and apps via APIs (neck). With every site and app having its own layout and design, the APIs define how your CMS is going to exchange information with them. The goal is to make all pieces of content appear in the right places and form coherent digital experiences.

Think about the content created in the console of a Headless CMS—texts, images, CTAs, and other pieces—as a set of building blocks. These blocks are sourced by developers building apps and sites, who fit them into pages of various shapes and designs.

How Headless Differs From Traditional

A traditional CMS (also called headful CMS) isn’t that flexible. It allows you to create and publish content on a particular property, with a particular design. First, you define the layout for pages on that property. Second, you create content that fits in this layout. If you need the same content on another property, you should go to another headful CMS and repeat the steps.

Most often traditional CMSs work on the backend of websites. They deliver content to browsers as static HTML pages. Headless CMSs are used on the backend of web apps (SPAs), mobile apps, and other JavaScript apps. They deliver content to the apps as JSON files. The following image illustrates the difference between headless and headful CMSs.

But let’s dig a little deeper and compare the two types of CMSs in detail.

The differences between the architectures and capabilities of headless and headful CMSs are huge. Yet, if necessary you can get the benefits from both and have a Hybrid CMS, where some content will live as static HTML pages for a site and another part will be fed into apps via APIs.

Now, let’s explore the possibilities that arise when AEM is transformed into a headless CMS.

How Adobe’s Headless CMS Works

Every Headless CMS has a complex system running under the hood and provides users with a unique content authoring experience. Let’s look at the AEM features that work together to bring to life the headless approach to content creation and delivery.

Content Services and HTTP APIs

One option to deliver content in a headless way is by using AEM Content Services. This feature helps you produce content in a traditional way. You’ll compose a Page out of AEM Components using a Template in a Drag-and-Drop Editor. The only difference is that you’ll get your content saved as an API Page in JSON data format instead of a regular HTML page.

Content Services will turn your API pages into REST API endpoints. Every endpoint will have a URL. Your mobile apps, IoT or smart device apps, in-store screens, or other properties, will be able to connect to these endpoints, consume content, and display it in their interfaces.

For example, you want the Contact Us page to be displayed in your mobile app and on your in-store screen. Then, you’ll put together information that should appear on this page, such as headlines, sales team members, CTA’s, etc., and save it as an API page. Each of the apps will consume the data and fit it into its own design and layout.

Content Fragments and GraphQL APIs

For a more granular and tailored content delivery, you can make your CMS and apps exchange smaller chunks of content rather than pages. For this, you can go down to the level of the AEM Content Fragments feature and send fragments of content to apps using GraphQL APIs.

To make it work, you’ll first create the information architecture for future Content Fragments. You’ll set Content Fragment Models using a Form-Based Editor. These models define the structure of data in future Content Fragments, by naming concepts and their attributes.

Using the models, you’ll create various Content Fragments—self-contained items of structured content—and store them organized in folders as AEM Assets.

You’ll be able to manage your Content Fragments through a Content Fragments console or AEM Assets console. At the same time, your frontend apps will be able to reach them directly through GraphQL API endpoints.

GraphQL is a query language that helps apps send requests to your CMS that target specific Content Fragments and get particular attributes from them for further processing and display. It allows getting various data in one request, which optimizes API usage and works for any app because it transfers data in JSON format.

For example, your mobile app can send a request to your CMS to source pictures, names, and titles of sales team members that should be displayed on the Contact Us page. GraphQL will reach all Content Fragments containing the sales team profiles, read through the attributes, pick only those that were requested, and send them to the app. The app will process this data and fit it into the page.

GraphQL vs. Content Services

Choosing between AEM GraphQL and AEM Content Services depends on your specific project requirements. Both APIs have pros and cons.

GraphQL may be the right choice if you need precise control over data retrieval, efficient network usage, and minimum API requests.

Steps to Headless Content Delivery

Let’s now describe the exact steps that you should make to prepare content and set up Headless AEM CMS.

1. Content modeling. Define the structure of your content in AEM by creating Content Fragments Models and Experience Fragments.
2. API Configuration. Enable and configure the GraphQL APIs in AEM to expose your content for headless consumption.
3. Templating and styling. Create templates and stylesheets in AEM to provide structure and visual consistency to your content. Customize the templates to generate JSON or XML representations. Use the AEM style system for branding and styling the output.
4. Frontend development: Build a frontend mobile or web app using JS frameworks (React, Angular, or Vue.js) and connect it to AEM to consume the headless content.
5. Testing and optimization. Validate content retrieval, rendering, and performance across various devices and channels. Optimize and refine your setup based on user feedback and insights from analytics tools.

With these steps, you can configure AEM as a powerful headless CMS, separating content management from delivery.

Challenges of using AEM as Headless CMS

Using AEM as a headless CMS offers numerous benefits, however, there are challenges to consider:

• Initial setup and configuration complexity. Setting up AEM as a headless CMS may require technical expertise and effort that’s currently missing from your team.
• Learning curve. Users may need time to familiarize themselves with AEM’s headless CMS features and workflows.
• Additional front-end development requirements. You should have custom frontend apps that would consume and display headless content.
• Managing multiple APIs and content delivery. Proper management and synchronization of multiple APIs and content delivery systems is required.
