This project is a set of class to manage dependency injection of application's part of a clean architecture app,
independently of the framework used.

Packagist : https://packagist.org/packages/small/clean-application

Install

composer require small/clean-application

Parameters

Parameters are managed to automatically inject them in UseCase constructor.

You can set parameters through the facade static object :

\Small\CleanApplication\Facade::setParameter('test', [ 'host' => 'http://clean.com', 'port' => 80 ]);

You can also get them through the facade :

echo \Small\CleanApplication\Facade::getParameter('test.host');

Output :

http://clean.com

UseCase class

Simple case

A use case is a class materialization of use case that implement SmallCleanApplicationContractUseCaseInterface.

For example, here is simply use case that return a string :

        

         Copy after login
        
       

You can use it using facade :

use Small\CleanApplication\Test\Feature\Fixture\UseCase\TestUseCase; use \Small\CleanApplication\Test\Feature\Fixture\UseCase\TestRequest; echo \Small\CleanApplication\Facade::execute(TestUseCase::class, new TestRequest());

Output :

a

Injecting another use case in your use case

You can inject another use case in the use case constructor :

getBefore() . $this->testUseCase->execute($request)->getStatus() ); } }

The property testUseCase will automatically be created as TestUseCase object.

Injecting parameters in your use case

You can inject parameters in your use case by typing and naming property in your use case constructor :

testUseCase_param . $request->getBefore() . $this->testUseCase->execute($request)->getStatus() ); } }

The underscrore ('_') separate array keys of parameters structure. Here is an example matching with the
$testUseCase_param :

\Small\CleanApplication\Facade::setParameter('testUseCase', ['param' => 'p']);

Interfaces

Three interface structure your code :

• SmallCleanApplicationContractUseCaseInterface: All your use cases must implement this interface
• SmallCleanApplicationContractRequest: All your use case requests must implement this interface
• SmallCleanApplicationContractResponse: All your use case response must implement this interface

Here's ourTestDependencyexample request class :

before; } }

And his interface :

        

         Copy after login
        
       

And here is the response implementation :

status; } }

And his interface :

        

         Copy after login
