Domain Events is an architecture pattern in which communication between various modules or components of an application is achieved through domain events. Domain events refer to significant actions or occurrences that take place within a system and are of interest to multiple components of the system. These events are raised by one module and consumed by other modules asynchronously.
The Domain Events architecture pattern follows the principles of Domain-Driven Design (DDD), where the domain model of the system is the core of the application. In this pattern, domain events are sent out from the Domain layer to one or more subscribers in other layers. These subscribers can include event handlers, which are responsible for executing certain actions in response to the raised event.
The Domain Events pattern helps in reducing coupling between different components of the system, as each component only needs to be aware of the events it is interested in. It also helps in ensuring that all relevant parts of the system are notified when significant changes occur, allowing for a more consistent and cohesive application design.
