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
  Config\app.php as providers.
• Step 4 − Create Class which is this class extends to
  lluminate\Support\Facades\Facade.
• Step 5 − Register point 4 to Config\app.php as aliases.

Example

Step 1 − Create a service provider called TestFacadesServiceProvider by executing the following command.

1	php artisan make:provider TestFacadesServiceProvider

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

1 2 3 4 5 6 7 8

<?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

1 2 3 4 5 6 7 8 9

<?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 TestFacadesServiceProviders.php at App/Test/Facades.

App/Providers/TestFacadesServiceProviders.php

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17

<?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 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

1 2 3

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

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

1	http://localhost:8000/facadeex

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