Component providers, same ones after navigation
We have a set of services that we want to be provided at the component level. The goal is to have the same instances of those services per composant.
The issue with putting it in the providers of the component is that the providers are actually tied to the element and not the component per se. So when you navigate to another page then come back, a new service is created.
To resolve that issue we created a custom RouteReuseStrategy where the component is reused when navigating but that brings a whole new set of problems because the ngOnInit and ngOnDestroy aren't called and that brings a whole set of other issues.
So what I'm asking is how can we manage to have the Services at the component level but not have the services recreated on every navigation?
