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.
Facade Class Reference
Laravel ships with many Facades. The following table show the in-built Facade class references −
Facade | Class | Service Container Binding |

Event | Illuminate\Events\Dispatcher | events |
File | Illuminate\Filesystem\Filesystem | files |
Gate | Illuminate\Contracts\Auth\Access\Gate | |

Example
Step 1 − Create a service provider called TestFacadesServiceProvider by executing the following command.
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
< ?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 TestFacadesServiceProviders.php at 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 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 −
