Rocketman help build event-based/pub-sub code in Ruby

Rocketman is a gem that introduces Pub-Sub mechanism within your Ruby code.The main goal of Rocketman is not to replace proper message buses like Redis PubSub/Kafka, but rather be a stepping stone. You can read more about the rationale behind the project down below.As with all Pub-Sub mechanism, this greatly decouples your upstream producer and downstream consumer, allowing for scalability, and easier refactor when you decide to move Pub-Sub to a separate service.Rocketman also works without Rails.
