Event Driven Updates with Apollo Subscriptions

What you'll learn

All too often, a client website’s data becomes stale and out of date with what is available on the server. A standard way to handle that is by implementing a polling system that has the client ping the server for up to date information at regular intervals. But there is a better way! In this course, Event Driven Updates with Apollo Subscriptions, you’ll learn to implement GraphQL subscriptions to keep your client and server in sync. First, you’ll learn how to implement subscriptions on the client side and explore what that means. Next, you’ll discover how to implement that subscription on the client side and keep your client page up to date. Finally, you’ll explore how to authenticate and filter subscriptions on both sides of the application. When you’re finished with this course, you’ll have the skills and knowledge of Apollo needed to build real time applications that keep their information up to date.
