This example shows an Action Domain Responder user interface subsystem, with the corresponding domain logic and data source elements, for a naive blogging system.
This is not a running example, in the sense that it cannot be dropped onto a web server and begin operating properly.
However, there is a full test suite in the
tests/ directory. (These are more properly considred integration rather than unit tests, but they will do for the purpose of this example.) Issue
composer install followed by
./vendor/bin/phpunit to run the tests.
There is no authentication, authorization, or session mechanism included. While necessary in a real system, they would increase the complexity of the example and make it more difficult to discern the separation of concerns.
The Action classes depend on 3rd-party HTTP Request and Response interfaces.
Each Action picks apart the incoming request to pass individual typehinted Domain method arguments. A differently-constructed Domain might require a different input signature, such as a data transfer object or a catch-all array of all possible request values.
The base ApplicationService class protects all the "real" service methods behind the magic
__call() method. This allows the service to implement some functionality common to all the service methods, such as exception handling, though it does get in the way of IDE auto-completion.
The BlogService methods return a domain Payload that wraps the domain results and includes a status indicator. This standardizes the domain return signature, makes the BlogResponder work much more readable.
The domain logic uses a Data Mapper for data source interactions (BlogMapper et al.).
Each Responder calls a method corresponding to the domain Payload status to build the HTTP Response.
The base Responder class depends on a 3rd-party HTTP Request interface and Response object.
The base BlogResponder class depends on a 3rd-party PHP-based Template View system. The templates are located in
