The main idea here is to create a reusable package. Following the principle "Domain Driven development" I define, all objects and the set of interactions we can perform in the objects inside the domain layer. This will not have any dependency. I use interfaces in order to separate definition from the implementation. This help us to do testing.

The, we have subpackages group by dependency. For example app subpackage is for business logic. HTTP is for all related to http functionality such as handlers, routes, etc. I also take into account, creating a wrapper when interacting with dependencies in order to decouple code.
