How to create custom facade in laravel 5.2?

Step 1:Create class file app/ItSolution/DemoClass.php

In Following step, first you should create “ItSolution” directory in app folder and create file DemoClass.php(app/ItSolution/DemoClass.php).now copy the following code in your DemoClass.php file.

app/ItSolution/DemoClass.php

namespace AppItSolution;
class DemoClass {
    public function productImagePath($image_name)
    {
        return public_path('images/products/'.$image_name);
    }
    public function changeDateFormate($date,$date_format){
		return CarbonCarbon::createFromFormat('Y-m-d H:i:s', $date)
					->format($date_format);
	}
}

Step 2:Create ServiceProvider

In this step you should create service provider for bind class, so fire your terminal or cmd this following command:

php artisan make:provider 'DemoClassServiceProvider'

Ok, now you can find new file DemoClassServiceProvider.php in your providers(app/Providers) directory.So, Basically open app/Providers/DemoClassServiceProvider.php and copy the following code:

app/Providers/DemoClassServiceProvider.php

namespace AppProviders;
use IlluminateSupportServiceProvider;
use App;
class DemoClassServiceProvider extends ServiceProvider
{
    /**
     * Bootstrap the application services.
     *
     * @return void
     */
    public function boot()
    {
        //
    }
    /**
     * Register the application services.
     *
     * @return void
     */
    public function register()
    {
         App::bind('democlass', function()
        {
            return new AppItSolutionDemoClass;
        });
    }
}

Step 3:Create Facade Class

In this step create another class app/ItSolution/DemoClassFacade.php, In this class you have to extend “IlluminateSupportFacadesFacade” class, copy following link:

namespace AppItSolution;
use IlluminateSupportFacadesFacade;
class DemoClassFacade extends Facade{
    protected static function getFacadeAccessor() { return 'democlass'; }
}

Step 4:Register Service Provider

Simple Register your service provider in Configapp.php like this way :

// In providers array
AppProvidersDemoClassServiceProvider::class,

And also add aliase for facade in this file like this way :

// In aliases array
'DemoClass'=> AppItSolutionDemoClassFacade::class

Step 5:composer dump

This is the last step and you have to do just composer dump-autoload in your terminal:

composer dump-autoload

At Last you can use this way:

Route::get('democlass', function(){
    $imagepath = DemoClass::productImagePath('image.jpg');
    print_r($imagepath);
});
