Events Service
Explore how to add subscribe and unsubscribe features to an Angular application. Learn to determine event creators, update event member lists, and write tests for these functionalities using mocked services and HTTP requests.
We'll cover the following...
At the moment, our dashboard only displays events that users create themselves. In this chapter, we’ll provide users the ability to subscribe to events created by other users, which will also be populated within the dashboard calendar.
We’ll add another module to our event view page that displays a list of the event’s members. In addition to the list of members, we’ll also add a button that will allow users to subscribe and unsubscribe to the event.
Below is our updated code. Use this code to make further changes.
