mediator-pattern

You can decouple components by introducing a central mediator that intercepts requests and routes them to appropriate handlers. This prevents direct component-to-component communication and reduces tight coupling in complex system architectures.

The mediator pattern is a design pattern that centralizes communication between multiple components. You should use it in scenarios with multiple interacting components, such as chat rooms, event routing, or cross-module coordination, to improve maintainability.

To set up a central mediator for request routing, instantiate a Mediator object and register your specific handlers. Once handlers are registered, you can route requests through the mediator to observe the decoupled communication flow.

Yes, the mediator pattern supports middleware-style processing chains. The central mediator can use these chains to modify and forward requests sequentially before delegating them to the appropriate handlers for execution.

You should avoid using a centralized mediator for component communication if your architecture has very few interacting components. Introducing a mediator in simple systems adds unnecessary routing overhead and complexity instead of improving maintainability.
