Event Sourcing and CQRS Sample
A sample event-sourced CQRS application demonstrating domain events, command handling, and read model construction.
What is Event Sourcing and CQRS Sample?
Event Source CQRS Sample is a demonstration application that implements Event Sourcing and Command Query Responsibility Segregation (CQRS) patterns. It models a shop item's lifecycle—including buying, paying, and payment timeout scenarios—by capturing all state changes as domain events. The project serves as a practical reference for understanding how to structure applications using these architectural patterns.
Developers and architects learning or evaluating event sourcing and CQRS patterns, particularly those building domain-driven applications with complex state management needs.
It provides a clear, concise example of ES/CQRS implementation with a real-world shop item domain, making it easier to grasp these patterns without the overhead of a full production system.
