Laravel - Facades

Facades provide a static interface to classes that are available in the application's service container. Laravel facades serve as static proxies to underlying classes in the service container, providing the benefit of a terse, expressive syntax while maintaining more testability and flexibility than traditional static methods.

How to create Facade

The following are the steps to create Facade in Laravel −

• Step 1 − Create PHP Class File.

• Step 2 − Bind that class to Service Provider.

• Step 3 − Register that ServiceProvider to

  Configapp.php as providers.

• Step 4 − Create Class which is this class extends to

  lluminateSupportFacadesFacade.

• Step 5 − Register point 4 to Configapp.php as aliases.

Example

Step 1 − Create a service provider called TestLaravel - Facades by executing the following command.

php artisan make:provider TestLaravel - Facades

Step 2 − After successful execution, you will receive the following output −

Step 3 − Create a class called TestFacades.php at App/Test.

App/Test/TestFacades.php

<?php
   namespace App\Test;
   class TestFacades{
      public function testingFacades() {
         echo "Testing the Facades in Laravel.";
      }
   }
?>

Step 4 − Create a Facade class called “TestFacades.php” at “App/Test/Facades”.

App/Test/Facades/TestFacades.php

<?php

namespace app\Test\Facades;

use Illuminate\Support\Facades\Facade;

class TestFacades extends Facade {
   protected static function getFacadeAccessor() { return 'test'; }
}

Step 5 − Create a Facade class called TestLaravel - Facadess.php at App/Test/Facades.

App/Providers/TestLaravel - Facadess.php

<?php

namespace App\Providers;

use App;
use Illuminate\Support\ServiceProvider;

class TestLaravel - Facades extends ServiceProvider {
   public function boot() {
      //
   }
   public function register() {
      App::bind('test',function() {
         return new \App\Test\TestFacades;
      });
   }
}

Step 6 − Add a service provider in a file config/app.php as shown in the below figure.

config/app.php

Step 7 − Add an alias in a file config/app.php as shown in the below figure.

config/app.php

Step 8 − Add the following lines in app/Http/routes.php.

app/Http/routes.php

Route::get('/facadeex', function() {
   return TestFacades::testingFacades();
});

Step 9 − Visit the following URL to test the Facade.

http://localhost:8000/facadeex

Step 10 − After visiting the URL, you will receive the following output −
