This document discusses Sitecore SXA and JSS snippets. It provides an agenda that includes explaining SXA shared data and snippets, custom JSS snippets, and a demo. It notes that SXA snippets are not supported by SXA JSS out of the box and describes creating a custom JSS snippet component and layout service to address this. Potential improvements to the custom snippet are also mentioned such as replacing HTTP calls and using Redis caching.
