Layers
Learn about the layers in hexagonal architecture and how they interact with each other.
We'll cover the following...
As with any other architectural pattern, hexagonal architecture defines some layers that should be followed. We will learn about these layers in this lesson.
The layers of hexagonal architecture
Hexagonal architecture defines four layers to structure a component. As was mentioned before, these layers are focused on all of the parts that an application consists of, such as frameworks, database connections, business flows, and so on. Let’s look at them one by one.
Domain objects layer
Located in the center of the hexagon, a domain contains all of the objects related to the business. In DDD terms, business objects ...
