kickstarter/event-sourcing-rails-todo-app-demo

This system is a minimal Rails-based demonstration of an event-sourcing architecture for managing TodoLists and TodoItems. It implements a command-driven workflow where user actions generate domain events that are persisted and dispatched to asynchronous reactors. The codebase includes a custom code generator to scaffold commands, events, and reactors, alongside database migrations and comprehensive test coverage for the core domain models.
