Laravel allows access to a variety of classes called Services. Some services are available out of the box, but you can create them by yourself. A service can be used in multiple files of the application, like controllers. Let's imagine a Service OurService implementing a getNumber() method returnin...

In a Service Provider register method we can bind an interface to an implementation: public function register() { App::bind( UserRepositoryInterface::class, EloquentUserRepository::class ); } From now on, everytime the app will need an instance of UserRepositoryInterface, Larave...

The Service Container is the main Application object. It can be used as a Dependency Injection Container, and a Registry for the application by defining bindings in the Service Providers Service Providers are classes where we define the way our service classes will be created through the applicatio...

This method will work on modern versions of Arch, CentOS, CoreOS, Debian, Fedora, Mageia, openSUSE, Red Hat Enterprise Linux, SUSE Linux Enterprise Server, Ubuntu, and others. This wide applicability makes it an ideal as a first approach, with fallback to other methods if you need to also identify o...

To cancel a call to requestAnimationFrame, you need the id it returned from when it was last called. This is the parameter you use for cancelAnimationFrame.
