I'm trying to do affix or scrollspy functionality of Bootstrap 4 on Angular 6. However, I trying to find existing libraries. I found this one JonnyBGod's scrollspy but unfortunately, it is still on Angular 5 and also using the rxjs 5. Are there any existing libraries out there that are already using RxJS 6. can you guys recommend?
BTW, I am trying to at least make JonnyBGod's library work with angular 6 by using the rxjs's migration guide. But if anyone knows any library out there that is natively written using angular 6 it is very much appreciated.
