Resources for Learning AEM Sling Context-Aware Configurations

Since learning how to use Sling Context-Aware Configurations (CA-Config) was a rabbit hole of information, I wanted to provide one source for learning how to use CA-Configs in Adobe Experience Manager (AEM) 6.2+.  I have ordered these in the way that I think it’s easiest to understand the possibilities of where and when you would use CA-Configs.

Overview

The most informative resource is this series of blog posts from Jörg Hoh here: https://cqdump.wordpress.com/sling-context-aware-configuration/.  I recommend reading the series from beginning to end as a starting point. Here are links to the individual posts in order:

Apache Sling Documentation

Once you have this base level understanding I think the Apache Sling documentation makes more sense and becomes useful: https://sling.apache.org/documentation/bundles/context-aware-configuration/context-aware-configuration.html

wcm.io Context-Aware Configuration Editor Template

You may have noticed references to the wcm.io editor for CA-Configs.  The next thing to dive into is learning more about the editor.  There is a useful YouTube video from the 2017 AdaptTo() conference by Stefan Seifert which also discusses using CA-Configs in AEM.

Here is the documentation which explains the editor http://wcm.io/caconfig/ and its usage (with screenshots) http://wcm.io/caconfig/editor/usage.html
