This is a fork from lagdo/symfony-facades with support for symfony 6.

Facades for Symfony services

With this package, Symfony services can be called using facades, with static method syntax.

It is a simpler alternative to passing services as parameters in the constructors of other classes, or using lazy services. It will be especially interesting in the case when a class depends on many services, but calls each of them only occasionally.

Installation

Install the package with composer.

composer require marcbln/symfony-facades

If the project is not using Symfony Flex, then register the Marcbln\Symfony\Facades\FacadesBundle bundle in the src/Kernel.php file.

Usage

A facade inherits from the Marcbln\Symfony\Facades\AbstractFacade abstract class, and implements the getServiceIdentifier() method, which returns the id of the corresponding service.

namespace App\Facades;

use App\Services\MyService;
use Marcbln\Symfony\Facades\AbstractFacade;

class MyFacade extends AbstractFacade
{
    /**
     * @inheritDoc
     */
    protected static function getServiceIdentifier()
    {
        return MyService::class;
    }
}

The methods of the App\Services\MyService service can now be called using the App\Facades\MyFacade facade, like this.

class TheService
{
    public function theMethod()
    {
        MyFacade::myMethod();
    }
}

Instead of this.

class TheService
{
    /**
     * @var MyService
     */
    protected $myService;

    public function __construct(MyService $myService)
    {
        $this->myService = $myService;
    }

    public function theMethod()
    {
        $this->myService->myMethod();
    }
}

Using a service locator

The above facade will work only for services that are declared as public.

A service locator must be declared in the config/services.yaml file, in order to create facades for private services. See the Symfony service locators documentation.

In the following example, the Twig service is passed to the service locator.

    marcbln.facades.service_locator:
        public: true
        class: Symfony\Component\DependencyInjection\ServiceLocator
        tags: ['container.service_locator']
        arguments:
            -
                Twig\Environment: '@twig'

A facade can then be defined for the Twig service.

namespace App\Facades;

use Twig\Environment;
use Marcbln\Symfony\Facades\AbstractFacade;

class View extends AbstractFacade
{
    /**
     * @inheritdoc
     */
    protected static function getServiceIdentifier()
    {
        return Environment::class;
    }
}

Templates can now be rendered using the facade.

use App\Facades\View;

class TheService
{
    public function theMethod()
    {
        ...
        $html = View::render($template, $vars);
        ...
    }
}

Provided facades

This package provides facades for some Symfony services.

Logger

The logger service must be passed to the service locator in the config/services.yaml file.

    marcbln.facades.service_locator:
        public: true
        class: Symfony\Component\DependencyInjection\ServiceLocator
        tags: ['container.service_locator']
        arguments:
            -
                Psr\Log\LoggerInterface: '@logger'

Messages can now be logged using the facade.

use Marcbln\Symfony\Facades\Log;

Log::info($message, $vars);

View

The twig service must be passed to the service locator in the config/services.yaml file.

    marcbln.facades.service_locator:
        public: true
        class: Symfony\Component\DependencyInjection\ServiceLocator
        tags: ['container.service_locator']
        arguments:
            -
                Twig\Environment: '@twig'

Views can now be rendered using the facade.

use Marcbln\Symfony\Facades\View;

$html = View::render($template, $vars);
