AmsterdamPHP Monthly Meeting - July/2019
18 Jul 2019 at Amsterdam

The Big Ball of Mud is the most serious problem I see in the majority of the code bases I look at. But why do we keep falling into that trap? What are the root problems behind it? How can we avoid, escape, and stay out of it? In this talk, you will learn about the architecture mental map (https://herbertograca.com/2017/11/16/explicit-architecture-01-ddd-hexagonal-onion-clean-cqrs-how-i-put-it-all-together) I use to answer these questions. We will briefly revisit a few established software development and architecture ideas and see how you can put them in your service, exemplifying with some bits of code and tooling, to help keep the mud out of your application. The main topics of the talk are: - The Big Ball of Mud problem - Overview of DDD, Hexagonal, Onion, Screaming, Clean, CQRS - How to organise the code base to reflect architecture boundaries - How to enforce the architecture boundaries
