Event Driven Application

Presented by Prasetyo Wicaksono (@praswicaksono)

In this talk I want to present Event Driven Application by using mediator pattern. It would help decouple your code but beware there are some cons by using this pattern such as hard to track if your apps grown bigger.

3. Event @phpconfasia  event is an action or occurrence recognized by software that may be handled by the software. Computer events can be generated or triggered by the system or by the user. Event can be defined as "a significant change in state“ – wikipedia

9. Mediator Interface @phpconfasia
10. Hook @phpconfasia  In computer programming, the term hooking covers a range of techniques used to alter or augment the behavior of an operating system, of applications, or of other software components by intercepting function calls or messages or events passed between software components. Code that handles such intercepted function calls, events or messages is called a "hook". - wikipedia
11. Example @phpconfasia
12. Prioritize Listener @phpconfasia Client Event Mediator 1 – Make sure title is upper case 2 - Uppercase Title 3 - Sanitize Body
13. I can’t handle this @phpconfasia
14. Notify Only ‘Hooks’ @phpconfasia  Don't change behavior  Only notify activity such as logging, sending email, updating cache
15. Example @phpconfasia
16. Notify Only ‘Hook’ + Background Process = @phpconfasia
