laravel-clean-architecture

Package to simply setup a Clean Architecture Application in Laravel.

Requirements

• PHP >= 7.4;
• composer.

Installation

composer require onramplab/laravel-clean-architecture

Features

UseCase

The UseCase class combines both DTO and business logic into single class in order to reduce the number of files since the DTO usually is tight to a specific use case. Here are the features when creating your own UseCase classes:

• Define a DTO
  • Define fields with validation rules (You can create your own validation attributes).
• Define the business logic.

Usefull logs

By using our exception handler, you will have better logging and API error response (We follows JSON API Spec). It will include more contexts.

Here is the example of api error response:

{
  "errors": [
    {
      "title": "Fake Domain Exception",
      "detail": "A fake message",
      "status": 400
    }
  ]
}

Here is the example of error log context:

{
  "detail": "A fake message",
  "adapter": {
    "type": "API",
    "route": "test-route",
    "method": "GET",
    "url": "http://localhost/test-route",
    "input": []
  },
  "errors": [
    {
      "title": "Unable To Do Something",
      "detail": "A fake message",
      "exception_class": "OnrampLab\\CleanArchitecture\\Exceptions\\UseCaseException",
      "stacktrace": [
        "## /var/www/html/tests/Unit/Exceptions/HandlerTest.php(149)",
        "#0 /var/www/html/vendor/phpunit/phpunit/src/Framework/TestCase.php(1548): OnrampLab\\CleanArchitecture\\Tests\\Unit\\Exceptions\\HandlerTest->handleUseCaseException2()"
      ]
    },
    {
      "title": "Fake Domain Exception",
      "detail": "A fake message",
      "exception_class": "OnrampLab\\CleanArchitecture\\Tests\\Unit\\Exceptions\\FakeDomainException",
      "stacktrace": [
        "## /var/www/html/tests/Unit/Exceptions/HandlerTest.php(146)",
        "#0 /var/www/html/vendor/phpunit/phpunit/src/Framework/TestCase.php(1548): OnrampLab\\CleanArchitecture\\Tests\\Unit\\Exceptions\\HandlerTest->handleUseCaseException2()"
      ]
    }
  ]
}

    • DomainException
    • CustomDomainException
  • Application Layer
    • UseCaseException
    • InternalServerException
  • Adapter Layer
    • Low level exception

How To

How to create an use case

namespace App\UseCases;

use OnrampLab\CleanArchitecture\UseCase;
use Spatie\LaravelData\Attributes\Validation\Url;

class DoSomethingUseCase extends UseCase
{
    #[Url()]
    public string $url;

    public function handle(): string
    {
        return 'do something';
    }
}

And then in your controller:

use App\Http\Controllers\Controller;
use App\UseCases\DoSomethingUseCase;
use Illuminate\Http\Request;

class DoSomethingController extends Controller
{
    public function doSomething(Request $request)
    {
        $result = DoSomethingUseCase::perform([
            'url' => $request->input('url'),
        ]);

        return response()->json([
            'result' => $result,
        ]);
    }
}

How to replace exception handler

Make your Laravel default handler to extend our Handler. For example:

namespace App\Exceptions;

use OnrampLab\LaravelExceptions\Handler as ExceptionHandler;

class Handler extends ExceptionHandler
{
   // ...
}

How to add custom validation attributes

You can follow the document in Creating your validation attribute.

Changelog

To keep track, please refer to CHANGELOG.md.

Contributing

1. Fork it.
2. Create your feature branch (git checkout -b my-new-feature).
3. Make your changes.
4. Run the tests, adding new ones for your own code if necessary (phpunit).
5. Commit your changes (git commit -am 'Added some feature').
6. Push to the branch (git push origin my-new-feature).
7. Create new pull request.

Also please refer to CONTRIBUTION.md.

Folder Structure

This will create a basic project structure for you:

• /build is used to store code coverage output by default;
• /src is where your codes will live in, each class will need to reside in its own file inside this folder;
• /tests each class that you write in src folder needs to be tested before it was even "included" into somewhere else. So basically we have tests classes there to test other classes;
• .gitignore there are certain files that we don't want to publish in Git, so we just add them to this fle for them to "get ignored by git";
• CHANGELOG.md to keep track of package updates;
• CONTRIBUTION.md Contributor Covenant Code of Conduct;
• LICENSE terms of how much freedom other programmers is allowed to use this library;
• README.md it is a mini documentation of the library, this is usually the "home page" of your repo if you published it on GitHub and Packagist;
• composer.json is where the information about your library is stored, like package name, author and dependencies;
• phpunit.xml It is a configuration file of PHPUnit, so that tests classes will be able to test the classes you've written;
• .travis.yml basic configuration for Travis CI with configured test coverage reporting for code climate.

Tech Features

• PSR-4 autoloading compliant structure;
• PSR-2 compliant code style;
• Unit-Testing with PHPUnit 6;
• Comprehensive guide and tutorial;
• Easy to use with any framework or even a plain php file;
• Useful tools for better code included.
