Downstream

Services & Skills

Share on

Downstream is a straightforward way to implement communication between Rails Engines using the Publish-Subscribe pattern. The gem allows decreasing the coupling of engines with events. An event is a recorded object in the system that reflects an action that the engine performs, and the params that lead to its creation.
