Description

All too often, a client website’s data becomes stale and out of date with what is available on the server.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.

Course Overview
Hi, everyone. My name is Jonathan Mills, and welcome to my course, Event Driven Updates with Apollo Subscriptions. I'm a cloud application architect at World Wide Technology, and with modern web applications, keeping what's on the screen up to date with changes happening elsewhere in the application can be a bit of a challenge. And in this course, we're going to talk about one way to solve that problem by using GraphQL and Apollo subscriptions to update the data on the client side in real time as changes are made on the back end. Some of the major topics we're going to cover include building out a subscription API on the back end, so we'll build the back end, consuming that subscription on the front end, securing that subscription using a token‑based authentication, so we're going to secure the API, and then filtering subscriptions by adding some variables to it. Now by the end of this course, you'll know everything you need to do to build out an API and consume an API using Apollo subscriptions. Now before beginning this course, you should be familiar with GraphQL and Apollo. This course is going to build on top of that knowledge that you already have. I hope you'll join me on this journey to learn about event‑driven updates with GraphQL and Apollo at Pluralsight.
