HexagonalJsonApi

This is a very simple pattern for modeling Rails JSON API requests in different layers based on their different responsibilities:

• Use Case Services - Each service executes a single Controller action's work
• Validators - Services use one or more Validator objects to validate/authorize the request
• Presenters - Formats the result data returned by the Service execution
• Data Objects - Services encapsulate the result data in a single data object which can pass through the narrow interface between the Service and the Presenter.
• Responses - Encapsulates the final response to give back to the Controller

The app's business logic can be further abstracted out into logic classes that are invoked by the Services.

Benefits:

• Each layer is segregated and can be tested independently.
• Narrow, Hardened interfaces between the different layers.
• Service and Presenter combinations can be changed easily.
