Laravel - Facades

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

Laravel comes with many facades. The following table shows the built-in references to the Facade class −

example

Step 1: Create a service provider named TestFacadesServiceProvider by running the following command.

php artisan make:provider TestFacadesServiceProvider

Step 2 − Upon successful execution, you will get the following output −

Step 3 − Create a class named TestFacades.php in App/Test .

Application/Test/TestFacades.php

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

Step 4 − Create a Facade class named "TestFacades.php" in "App/Test/Facades" .

Application/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 Facade class named TestFacadesServiceProviders.php in App/Test/Facades.

App/Providers/TestFacadesServiceProviders.php

<?php

namespace App\Providers;

use App;
use Illuminate\Support\ServiceProvider;

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

Step 6 − Add Service Provider in config/app.php file as shown in the image below.

config/app.php

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

config/app.php

Step 8 - Add the following lines to app/Http/rout.php.

app/http/routes.php

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

Step 9 − Visit the following URL to check Facade.

http://localhost:8000/facadeex

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