📄️ Introduction
In the ports and adapters model, the application is divided into two distinct parts:
📄️ Use Cases
A use case in this context is an encapsulated piece of business logic that performs a specific function or process in response to a request from an external source. For example, in a banking application, a use case might be "Transfer Money", "Check Balance", or "Create New Account". Each of these use cases represents a distinct set of steps or actions that need to be performed to achieve a particular business objective.
📄️ Primary vs Secondary Adapters
Adapters can be classified as primary or secondary based on the purpose of the adapter and direction of data flow relative to the core application.
📄️ Benefits of Hexagonal Architecture
Improved Testability
📄️ An Insurance Themed Example
Let's implement a use case for lodging an insurance claim. This use case will demonstrate the practical application of hexagonal architecture principles and the benefits they offer, including improved testability, flexibility, ease of maintenance, scalability, enhanced portability, and facilitation of domain-driven design.
