Capstone - Designing a Notification System

1. How This Capstone Works

Seven lessons, seven ways to move data. Now we find out whether you can use them together. Communication patterns are not steps you apply in order. They are a decision you make once per arrow in your diagram. A notification system is a good final exam, because it contains every kind of arrow this module taught: facts coming in, jobs flowing through, calls going out to providers, webhooks coming back, streams going down to browsers, and deliveries crossing into other companies' systems.
