How to access host component from directive?
Say I have the following markup:
<my-comp myDirective></my-comp>
Is there any way I can access the component instance from the directive?
More specifically I want to be able to access the properties and methods of MyComponent from MyDirective, ideally without adding anything to the HTML above.
Answer
You can just inject it
class MyDirective {
constructor(private host:MyComponent) {}
A severe limitation is, that you need to know the type of the component in advance.

It also provides some workarounds for when you don't know the type in advance.
