This is a complete RxJS tutorial with details explanations, code examples and a lot of references to further sharpen your skills. In this tutorial, you will learn the core concepts of reactive programming and how to achieve them in RxJS. Learning RxJS could be hard, especially to think in a reactive programming way. But, trust me it is worth learning. I have tried to provide you the ultimate tutorial with guidelines, so you don’t have to struggle much finding the resources.

Course Prerequisites

RxJS helps in doing a lot of complex events handling in a simple and clean way. Therefore, you are expected to understand the following concepts well before learning RxJS in detail.

  • Functions, Events, and Error handling mechanisms in JavaScript
  • Asynchronous JavaScript Patterns (especially, the Callbacks and Promises).
  • Basic knowledge of Data handling in JS.

Course Contents

  1. Introduction to RxJS and reactive programming
  2. RxJS Building Blocks
  3. RxJS Observable in depth
  4. RxJS Subscription – represents a disposable resource
  5. RxJS Subject in-depth – Multicast values
  6. RxJS Scheduler – asyncScheduler, queueScheduler, asapScheduler
  7. RxJS buffer operator
  8. RxJS ajax operator – Creation operators

Useful references and tools:

  1. Rx Visualizer – An animated playground for Rx Observables
  2. RecativeX Official documentation
  3. Official RxJS
  4. Learn RxJS ebook
  5. What the heck is the event loop anyway?
