I am trying to trigger component method with parameter from service.
Lets say I have component
myComponent.ts
myMethod(myParameter: string){
...
}
How can i trigger that method with custom parameter from service? I know its not best practice.
>Solution :
The approach you have described is distinctly "un-Angular". Services don’t call methods on components.
As mentioned in the comments on your post, the "correct" way of achieving the behaviour you want (component reacts to change in service) is to use an Observable.
Your service will expose some form of Observable-like stream (Observable, Subject, BehaviorSubject) and the component will subscribe to it in order to react to its emissions.
Yes it’s "more difficult", but it’s the best practice and the only clean way of achieving what you’re looking for.
