Facades provide astaticinterface to classes that are available in the application's service container. Laravelfacadesserve asstatic proxiesto underlying classes in the service container, providing the benefit of a terse, expressive syntax while maintaining more testability and flexibility than traditional static methods.
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.
Laravel ships with many Facades. The following table show the in-built Facade class references −

Step 1− Create a service provider calledTestFacadesServiceProviderby 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 calledTestFacades.phpatApp/Test.
App/Test/TestFacades.php
Step 4− Create a Facade class called“TestFacades.php”at“App/Test/Facades”.
App/Test/Facades/TestFacades.php

Step 5− Create a Facade class calledTestFacadesServiceProviders.phpatApp/Test/Facades.
App/Providers/TestFacadesServiceProviders.php

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

config/app.php
Step 8− Add the following lines inapp/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 −
