When a manager gives us the requirements for an application feature, they don't care too much about how we build it. And often times, they think that hard things will be easy.

Dealing with time and coordinating different types of events can be tricky.

Luckily, we have RxJS to help!

In this course, you will use RxJS to build a loading spinner in an app that meets the ever-changing requirements from a mock Product Manager.

You'll also learn how to implement a "Konami Code" style feature that listens for a correct sequence of keys to be typed in a set amount of time.

Follow the thought process that Rares uses as he breaks problems down into manageable pieces that remain flexible, and become more comfortable solving problems reactively.

What you'll learn:

  • RxJS Operators: flatMap, mapTo, merge, scan, and more
  • Creating observables
  • Building operators
  • Converting written requirements to code
  • Reactive problem solving

    What did you like about this course?

    An incredible course! Thanks for it!

    The only improvement that comes to my mind is to explain more about what the operators do and provide more knowledge about reactive programming in general since it is hard to grasp every concept if you have a little experience with reactive programming.

    What would make this collection a 7 for you?

    Good level of problem to solve, but for me various choices were made where alternative options were not discussed, so the format is "do X", not "we could do X or Y but X is better because...". One example would be whether showSpinner and hideSpinner is 2 separate observables, or observable 1 with true/false values emitted. Is it a truism that 2 separate is always better, or is the choice made because you wanted to use takeUntil?

    What would make this course a 7 for you?

    A little more care in naming functions and variables. As an example of this issue: it can become confusing when you name the argument the same as the function (comboKeys).
