📏 Rules

This project follows clean architecture rules. Each of the layers communicates with each other using abstraction and the lower layers know nothing about the upper layers.

We can distinguish four layers in this repository:

• api - here a server is prepared to communicate with the outside world using the REST API powered by express. With the lower layer it communicates only using the command bus and query bus.

• app - this layer is responsible for the implementation of commands and queries available in the application. According to the CQRS pattern.

• infrastructure - layer responsible for concrete implementations of external tools, e.g. persistence layer is implemented using postgresql.

• core - layer that is responsible for creating and managing domain objects.
