The Domain hexagon is the place to start developing a hexagonal application. Based on the domain, we derive all other hexagons. We can say that the Domain hexagon is the brain of hexagonal systems because the core fundamental business logic resides in such a hexagon.
So, in this chapter, we will start to explore how to structure from the very bottom of a hexagonal application project using a Java module approach. This will help us ...
