What you’ll learn

  • Code in Github repository with downloadable ZIP files per section
  • Learn the RxJs library via Practical Examples
  • Become familiar with an extended subset of RxJs Operators
  • Understand in detail the core notions of Reactive Programming

  • Just a bit of Javascript
  • No previous knowledge of Typescript or Angular is needed
  • No previous knowledge of RxJs is needed, we will start from scratch


This Course in a Nutshell  (note: this course includes the Typescript Jumpstart E-Book)

This course is a complete practical guide for the RxJs library (Reactive Extensions for Javascript).

If you are a developer just getting started with the Angular ecosystem, or even if you already have some experience with it, the part that you will find the hardest to wrap your head around is RxJs.

And this is because RxJs and Reactive Programming have a steep learning curve that makes it hard to just jump in into an existing program and learn these concepts by example. With RxJs that approach will simply not work. Instead, we need to start at the beginning and learn some baseline reactive design concepts first.

In this course, we will start by presenting a couple of baseline concepts, and then we will provide you with an extended catalog of RxJs operators that will in practice cover the vast majority of your daily needs.

Also, the goal here is not to cover every single operator, but instead to choose an extended subset that contains the most commonly used operators, and provide practical examples for each. RxJs In Practice RxJs In Practice

Another goal of the course is to show how RxJs is meant to be used for building programs using Reactive Design as opposed to an imperative programming style.

Course Overview RxJs In Practice RxJs In Practice

We will start by quickly introducing RxJs: we will cover the notions of Stream and Observable, and we will answer common questions such as: what is RxJs, when to use it and why, what problem does it solve?

We will then write our own Observable from first principles: we will implement our own HTTP observable that will allow us to handle backend HTTP requests while supporting error handling and cancellation.

After this quick introduction, we will dive straight into the practical examples covering a large variety of operators. We will cover the operators by explaining their behavior using the official RxJs marble diagrams, and then we will complement that with a practical example.

Who this course is for:

  • Developers trying to make sense of the RxJs library
  • Developers looking to learn Reactive Programming
  • Developers trying to understand how to build Applications in a Reactive Design style
