Subscribe to observable is returning undefined

Question

So I am trying to subscribe to a simple service that return data from a local JSON file.

I have managed to get the service working, I can log it out in the function

Answer 1

you can do it like this:

In your app-component:

public getDataFromService() {
  this._api.getData(this);
}


public setData(data: any){
 this.data=data;
}

In your service/api.ts:

public getData(obj: appComponentModel){
    this.http.get(url).subscribe(res => obj.setData(res));
}
