Mediator​

  • Before

    • Tightly coupled components with function’s endpoint in the controller class.
    • No business logic isolation from components that has no relation with business logic
    • Enormous and Monolithic Controller files.

  • After

    • Deal with controllers as just a layer of abstraction that encapsulate business logic beneath it!
