This project is a simple example of how to incrementally apply the components of event sourcing into an existing system.
It starts with a basic rails app with a single account.rb model.
Checkout each branch and compare it to the previous one to learn about:
001_encapsulate_changes- name the events002_create_event_objects- create an object for events003_unify_event_handling- use generic interface for handling events004_persist_events- create in-memory event-store for saving/retrieving005_projectors- create subscribers and projectors, separate read & write objects006_commands- create command objects for handling requests and validations007_reactors- react to event by doing something else
