Dependency Injection

Introduction

doMynation uses dependency injection to wire dependencies across the framework.

Container-Aware Entities

Below is the list of classes and methods supplied by the framework that are aware of the dependency injection container, which means they can be injected dependencies via constructor arguments or function/method arguments:

• The Module::boot() method

• Closures of simple routes

• Constructor of Actions and their optional validate() method

• Constructor of RouteMiddleware

Core Dependencies

The framework registers and makes the following dependencies available in any container-aware entity:

Class/Interface	Description
