eseménybuszokkal

Eseménybuszokkal, which translates to "event buses" in English, refers to a software design pattern used for inter-process communication and decoupling components within an application. Instead of direct communication between specific sender and receiver objects, components publish events to an event bus, and other components subscribe to specific types of events. When an event is published, the event bus delivers it to all subscribed listeners.

This pattern promotes loose coupling, meaning that components do not need to know about each other's existence directly. A component only needs to know about the event bus and the events it's interested in. This makes the system more flexible, as components can be added, removed, or modified without affecting other parts of the application, as long as they adhere to the defined event contract.

Event buses are commonly used in various architectures, including microservices, event-driven architectures, and complex monolithic applications. They can facilitate asynchronous communication, allowing processes to continue their work without waiting for a response. This can improve performance and responsiveness. Common implementations involve message queues or dedicated event bus libraries. The choice of implementation often depends on factors like scalability requirements, message persistence needs, and the complexity of the event routing logic.
