This lesson is part of the Rxjs and Reactive Patterns Angular Architecture Course - https://angular-university.io/course/reactive-angular-architecture-course?utm=yt1&couponCode=RXJS_YOUTUBE_LAUNCH This course is fully up to date with the Angular 4 release. In this lesson we are going to learn how to leverage the Angular Dependency Injection System to manage state that is local to a certain section of the page. We are going to learn how to create state that is local to a given section via a Local Service, and we are going to see how the service will be linked to the lifecycle of the host component and how both the service and the data will get cleaned up transparently and automatically as we navigate around the page.
