QUESTION
I'm very new to IoC idea and I'm trying to jump over the Service Locator pattern. I chose the Kangaru implementation. Suppose I want to use Audio and Logger services in different places of my app. What I have now:
...ANSWER
Answered 2021-Jun-06 at 02:01The main advantages of using a library to handle dependency injection is:
- The automation of boilerplate code
- Having a central place that contains the instance about the current context
Using a dependency injection container, you have that single entity that contains the all the instances. It can be tempting to send that thing everywhere since you'll have the whole context available, but I would advise against.
In the kangaru documentation, I added this in the guidelines:
This library is a great tool to minimize coupling, but coupling with this library is still coupling.
So for example, if void f();
(as a free function) needs the logger, then it should be passed as parameter.
