While I still my post, I realize it is a bad practice.</p> <p>Last week I found some <a href="http://www.kamilgrzybek.com/">great articles</a> about <a href="https://martinfowler.com/tags/domain%20driven%20design.html">Domain Driven Design</a>. While I have been trying out various patterns and design principles like Clean Architecture and Domain Driven Design I was still finding out how to implement domain events. While doing some exercises I came up with a solution to validate domain entities with asynchronous validations which I want to share.</p>
