Think about your favorite apps that you use on a daily basis. Chances are that most, if not all, will have some form of real-time functionality. This also means that you, as a developer, will benefit from learning how to build real-time features for the products that you work on. In this course, Building Real-time Apps with React, Socket.io, and RethinkDB, you'll get a solid introduction to the stack used in the course, but more importantly, the patterns required to build real-time apps. First, you'll acquaint yourself with Socket.io and how to get it connected to a component in React. Next, you'll learn how you can use RethinkDB for data persistence and publish/subscribe. Finally, you'll explore how you can handle failover scenarios when dealing with a real-time stack. When you're finished this course, you'll have a solid understanding of the patterns involved when working on a real-time stack and how to overcome common real-time challenges.
