The service container binding key is also included where applicable. Search Electrical Inspection Establish or Upgrade Service Customer Guides. For the best experience using the FastBridge Learning system, please run a system compatibility check. This is a useful tool for quickly digging into the API documentation for a given facade root. For example, given the following route:īelow you will find every facade and its underlying class. However, since facades use dynamic methods to proxy method calls to objects resolved from the service container, we actually can test facades just as we would test an injected class instance. Typically, it would not be possible to mock or stub a truly static class method. This is useful during testing since you can inject a mock or stub and assert that various methods were called on the stub. One of the primary benefits of dependency injection is the ability to swap implementations of the injected class. If your class is getting too large, consider splitting it into multiple smaller classes. So, when using facades, pay special attention to the size of your class so that its scope of responsibility stays narrow. The Chino Valley Unified School District is committed to equal opportunity for all individuals in education and employment. Using dependency injection, this potential is mitigated by the visual feedback a large constructor gives you that your class is growing too large. Since facades are so easy to use and do not require injection, it can be easy to let your classes continue to grow and use many facades in a single class. The primary danger of facades is class "scope creep". However, some care must be taken when using facades. Furthermore, because of their unique usage of PHP's dynamic methods, they are easy to test. They provide a terse, memorable syntax that allows you to use Laravel's features without remembering long class names that must be injected or configured manually. So, we can easily access a facade like so:įacades have many benefits. It's perfectly fine if you don't totally understand how facades work under the hood - just go with the flow and continue learning about Laravel.Īll of Laravel's facades are defined in the Illuminate\Support\Facades namespace. 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. Laravel ships with many facades which provide access to almost all of Laravel's features. Facades provide a "static" interface to classes that are available in the application's service container. Throughout the Laravel documentation, you will see examples of code that interacts with Laravel's features via "facades".
