Command and event patterns

By: Miro Svrtan

Idea behind commands is to encapsulate all of the information needed for an action: making our domain less fragile and simple.

Event pattern help us decouple code and make it easily extendable: without modifying user registration process we can easily add more features like send ‘welcome SMS’ or ‘notify support to check new user’.

You will be building a small app using commands and events and you’ll see how nice and cool it is!
