React and Redux

React and Redux Courseware (RCTRDX)

Web DevelopmentJavaScriptReact

React makes creation of beautiful and capable web applications possible with much less work. It allows software developers to write ultra-modern web-based programs as part of large teams. Redux makes the management of web data extremely controllable. The combination of the two is powerful!

Using short, to-the-point TED-style lectures, this course leads you through both of these JavaScript libraries from scratch. We'll lay a foundation of the tooling for both libraries. Then we launch into an understanding of Redux from the ground-up, moving all the way into advanced topics like middleware and asynchronous Ajax calls through dispatchers. Finally, we'll learn how React works and how to integrate Redux into it.

We will get you up and running rapidly, preparing you for real-world application development with a deep understanding of React components and well-structured applications. If you are new to React and Redux, or if you've been working with it but not quite getting how it really works, this is the course for you!
