Rails Event Store

Rails Event Store (RES) is a library for publishing, consuming, storing and retrieving events. It's your best companion for going with an event-driven architecture for your Rails application.

You can use it:

  • as your Publish-Subscribe bus
  • to decouple core business logic from external concerns in Hexagonal style architectures
  • as an alternative to ActiveRecord callbacks and Observers
  • as a communication layer between loosely coupled components
  • to react to published events synchronously or asynchronously
  • to extract side-effects (notifications, metrics etc) from your controllers and services into event handlers
  • to build an audit-log
  • to create read-models
  • to implement event-sourcing
