PHP UK Conference 2018 - Barney Hanlon - Command and (e)mission Control

This talk explores the use of event dispatchers and command buses in applications, emphasizing their role in enhancing understanding within the context of Domain-Driven Design. The speaker discusses the significance of clearly differentiating between Events and Commands as applications grow smaller and adopt a hexagonal architecture. Through a practical example, the session illustrates how to effectively use command buses and event dispatchers together to create clean CQRS-based applications, promoting a more structured approach to application design.
