Why create a wrapper and not use the Rails Event Store itself?
R.E.S. is an awesome project, but, in our opinion, it lacks Rails simplicity and elegance (conventions and less boilerplate). It’s an advanced tool for advanced developers. We’ve been using it in multiple projects in a similar way, and decided to extract our approach into this gem (originally private).
Secondly, we wanted to have a store implementation independent API that would allow us to adapterize the actual event store in the future (something like
ActiveEventStore.store_engine = :rails_event_store or
ActiveEventStore.store_engine = :hanami_events).
