Rails_event_store

Overview

Rails Event Store (RES) is a versatile library designed for publishing, consuming, storing, and retrieving events. It serves as a valuable tool for implementing an event-driven architecture in your Rails application. With RES, you can decouple core business logic, create communication layers between components, react to events synchronously or asynchronously, extract side-effects from controllers and services, build audit logs, create read models, and implement event sourcing.

Features

• Publish-Subscribe Bus: Facilitates decoupling of core business logic from external concerns in Hexagonal style architectures.
• Alternative to ActiveRecord Callbacks and Observers: Provides a different approach to managing callbacks and observers in Rails applications.
• Communication Layer: Enables communication between loosely coupled components.
• Synchronous and Asynchronous Event Reaction: Allows reacting to published events in real-time or asynchronously.
• Extract Side-Effects: Helps in moving side-effects such as notifications and metrics out of controllers and services.
• Build Audit Logs and Read Models: Supports the creation of audit logs and read models within the Rails application.
• Event Sourcing: Facilitates the implementation of event sourcing for data storage and retrieval.
