Dependency Injection Explained
In today's stream, I talk about the basics of dependency injection. Dependency injection is a very common software design pattern that implements inversion of control for resolving dependencies.
What is a dependency? A dependency is an object that another object depends on.
What is injection? Injection is the passing of a dependency to a dependent object that would use it.
Essentially, dependency injection is a technique of injecting dependencies into objects that require them via either a constructor argument, or a property setter.
The intent behind dependency injection is to achieve separation of concerns of construction and use of objects. This can increase readability, extensibility, testing, and code reuse.
