It is Frontend Tech Online meetup!
Here is the plan:
18:00 - 18:05 Introduction
18:05 - 18:10 RxJS in 5 minutes
18:10 - 18:40 How to Build Your Own DevTools Extension
18:40 - 19:10 Hidden power of RxJS AsyncScheduler.delegate
19:10- 19:30 QnA, Panel discussion (Open Talk)
🚀 Aliaksei Kuncevič - This time we will talk a lot about RxJS so I've decided to give a quick 5 minutes intro in to RxJS for these who are not familiar with Observables and Reactive Programming concepts.
🔥 Nicholas Jamieson - Nicholas is freelance front-end developer, in Brisbane, Australia. He is an RxJS core team member and the author of several popular, open-source, RxJS-related packages. He blogs regularly, writing about RxJS concepts, internals and use cases.
These days Nicholas is working on building a DevTools extension for RxJS. In this talk, he'll show how Chrome/Firefox/Edge DevTools work, what's possible with a DevTools extension and how you can build your own.

💥 Oleksandr Poshtaruk - Senior front-end dev. Last 4+ years I’ve been working in commercial projects heavily using Angular and RxJS. He is a writer for ‘Angular-in-Depth’ blog. Speaker. "Hands-on RxJS" and “RxJS unit testing” Udemy video-courses and “Angular can waste your time” Youtube series author.
Observables unit testing is an important part of development. If code is asynchronous - RxJS uses AsyncScheduler to emit values. To test such Observables we may substitute AsyncScheduler with TestScheduler or VirtualTimeScheduler. So scheduler argument had to be added to method definition - and break code/test segregation! But there is a better solution - AsyncScheduler.delegate prop. And in my talk I will tell you how to use it (and how RxJS uses it too:)
