title: Angular 5 global components and their services
body: <p>Looking through Angular's docs, specifically the style guide, they lay out both a shared module and a core module. According to the docs, services should be placed in the core module and components in the shared module. My question is if I have a component, say a custom file upload component, and it also has a corresponding service, where should that component and service reside? It seems to make sense to keep the two together since the service is used with the component, however, this doesn't seem to follow Angular standards. Anyone come across this issue? </p>
