Sample code used during GeeksHubs online meetup talk 23/04/2020.
Simple ticketing system using concepts of Hexagonal Architecture and leveraging separation of concerns.
The code is divided in two main layers:
Core
- Entities: Business Objects
- Repositories: Interfaces to interact with the entities
- Interactors: Business logic, actions that the system can perform.
Inputs and Outputs
- DataSources: Outputs of our system implementing Repositories and connected to storage systems.
- Controllers: Inputs of our system encapsulating the transport layer. They should trigger the Interactors.
Note: The purpose of this code is to be used as a guide to explore hexagonal architecture and it is not supposed to run in production.
