The Complete RxJS Course

Learn and master the extremely popular reactive JavaScript library RxJS in this modern and up-to-date complete course.

Why did I create this course

When I first started my personal RxJS journey it felt quite intimidating, I didn’t really understand what was happening behind the scenes and often the documentation was not enough for me to fully understand how I could use a certain operator and when to use it.

However, eventually things started to click in my mind, after some practice and many years of professional experience with RxJS.

Through this course I want to lower this barrier of entryfor beginners by simplifying the RxJS library concepts as much as possible and to reduce the amount of effort needed to properly learn the powerful & extremely popular RxJS library. People that already have some knowledge of RxJs can also benefit from this course.

A couple of reasons why this course is different from any other RxJS tutorial online:

1. This course will be taught by an instructor that has actually used RxJS professionallyin a production environment of a thriving company. By learning RxJS through the perspective of my practical experience you will also learn things that are not directly found in the official documentation.

2. In this course we will be going straight to the point, by giving you all the juicy detailsin the span of a couple of hours.

3. We’ll be using interesting diagrams & analogies to explain the behaviors of all the RxJS elements and make it simple to understand what is going on.

4. In this course you will be using the latest RxJS versionavailable so you will not be learning about outdated concepts in RxJS.

5. You can expect exercisesthat are connected to real life situationsso that you get a real grip on the most important RxJS elements in a practical context. There will also be quizzes for you to solve after each major section.

6. In terms of operators we will focus on the most important ones that are used daily in real life so that we won’t waste any extra time or energy on the less important ones.

These are some of the topics we will cover in this course:

• Fundamental concepts

• Observables

• Subscriptions

• Observers

• Creation operators

• Pipeable operators

• Subjects

We will “kick-off” this course by starting with the foundation of RxJS by going through the fundamental concepts on which the RxJS library is built upon. You can’t build a house without a solid foundation!

Then we’ll go through the basics of Observables, how they function & behave, but also we’ll take a look at what’s happening inside. You’ll be quite surprised that it’s not some random magic!

After that we’ll look at Subscriptions,what they are, how to manage themand which approach is the best and why.

Throughout this course we’ll also explore the whole variety of different Observerfunctions and how we can use them for different use cases.

And of course we will also be taking a look at the most important creation & pipeableoperators. Creation operators do some of the heavy lifting for us while the Pipeable operatorsare more into transforming & influencing data flows.

We’ll wrap up the course by checking out the Subjectswhich are like the more sharing family member of the Observable.
