The developer's workshop covered the setup and usage of Couchbase Server, with four lab sections: setting up Couchbase, using Couchbase, building a full-stack application, and creating a simple cluster. The materials are open sourced, including slides, code samples in multiple programming languages, and completed versions for reference. Participants can provide feedback through GitHub issues or pull requests to enhance the workshop. Additionally, the creator offers customization services for conferences, user groups, or businesses interested in hosting a similar workshop.
