Within a service provider, you always have access to the container via the $this->app property. Secondly, if you are writing a Laravel package that you plan to share with other Laravel developers, you may need to bind your package's services into the container.Īlmost all of your service container bindings will be registered within service providers, so most of these examples will demonstrate using the container in that context. So, when would you ever manually interact with the container? Let's examine two situations.įirst, if you write a class that implements an interface and you wish to type-hint that interface on a route or class constructor, you must tell the container how to resolve that interface. In many cases, thanks to automatic dependency injection and facades, you can build Laravel applications without ever manually binding or resolving anything from the container. Even though we never have to interact with the container to write this code, it is managing the injection of these dependencies behind the scenes: For example, you might type-hint the Illuminate\Http\Request object on your route definition so that you can easily access the current request. Thanks to zero configuration resolution, you will often type-hint dependencies on routes, controllers, event listeners, and elsewhere without ever manually interacting with the container. Once you taste the power of automatic and zero configuration dependency injection it feels impossible to develop without it. 4) After that, solder a 220 Ohm resistor between pin 3 and pin 8 of the IC. 3) Solder the female header pins on the veroboard. 2) Solder a 33K Ohm resistor between pin 2 & 3 of the IC. Also short pin 2 & 6 of the 555 timer IC. Additionally, you may type-hint dependencies in the handle method of queued jobs. Useful Steps 1) Solder the NE555 timer IC on the veroboard. Thankfully, many of the classes you will be writing when building a Laravel application automatically receive their dependencies via the container, including controllers, event listeners, middleware, and more. It means you can develop your application and take advantage of dependency injection without worrying about bloated configuration files. In this example, hitting your application's / route will automatically resolve the Service class and inject it into your route's handler.
