Get angular 2 service inside a custom class instantiated by me

Question

Im building an angular 2 app, and i need a way to get a reference to a service/class that is injected/instantiated by angular framework.

I have a generic class...let

Answer 1

As far as I know you have two choices:

1) Manually pass the service into the Custom class constructor.

let x = new Custom(this.userService);

2) Make the Custom class a service as well. Then it will participate in Angular's DI.
