Rails Event Store (RES) is a Ruby library for publishing, consuming, storing, and retrieving domain events, built on Active Record. It serves as a publish-subscribe bus and event store for implementing event-driven architectures, event sourcing, CQRS, and audit logs in Rails applications.

Use cases

• implement event sourcing in a Rails application
• replace ActiveRecord callbacks and observers with domain events
• decouple core business logic from external concerns in hexagonal architecture
• build an audit log of domain events
• create read models with CQRS
• publish and subscribe to events synchronously or asynchronously
• extract side-effects like notifications and metrics into event handlers
• communicate between loosely coupled components

When to choose

• you are building a Rails application and want event-driven architecture
• you need event sourcing or CQRS with Active Record as the persistence layer
• you want to decouple domain logic from framework concerns like callbacks and observers
• you need a pub-sub event bus with sync/async handlers inside a monolith

When to avoid

• you need a standalone distributed event broker across services (consider Kafka or a dedicated event store)
• your project is not Ruby/Rails based
• you only need simple background job processing without event semantics
• you require non-ActiveRecord databases without an adapter
