mediator-pattern

To decouple components in TypeScript, introduce a central mediator object that coordinates requests and forwards them to the appropriate handlers. This removes the need for direct inter-object calls and eliminates tight dependencies.

Centralizing communication in JavaScript is best achieved by routing messages through a single mediator. This pattern acts as a routing layer, similar to a chatroom, where messages flow through one central hub instead of triggering direct dependencies.

Implementing a mediator with middleware chaining involves initializing a central mediator and progressively adding handlers. This middleware-style processing allows you to compose and extend processing steps without individual components knowing about each other.

You should use a central mediator for UI components and services when direct coupling creates hard-to-maintain code. It is applicable for middleware chains where requests must be routed and coordinated without building tight dependencies between interacting parts.

The mediator pattern does not require external dependencies to work in JavaScript. It only requires a central mediator object or function and support for middleware-style processing to coordinate interactions among multiple components.
