I only ever use these RxJS operators to code reactively

Показать описание

In this video, I cover the 10(ish) operators I most frequently use when coding reactively in Angular. We take a look at the theory for each one, along with a realistic example of where I have used it recently.

You are the man! There is such a shortage of angular and angular related content on YouTube. Especially content as good as this. Please keep up this good work. You’re really helping a lot!

The best channel I have seen so far. thanks a lot <3

why not use `from` in front of the `map` operator, then `toArray()` to aggregate the xfm? If you need to process the array as an array in your stream first, you can just `switchMap` into the `from`...

`concatMap` is great for enforcing synchronicity... but you have to ensure your observables actually complete... which (in certain scenarios) they'll stay open unexpectedly if you don't explicitely tell them to complete.

Great content. Would you plan to create mini projects for angular using reactive programming ??

have too many proprietary restrictions on the user and I want more freedom in importing and exporting projects, soft and video editing

Even a basic tutorial video is pretty much too complicated. I've just accepted I'll never make a soft using soft soft

Great videos and explanations - providing real world uses cases are some of the best parts of your videos. There is not enough of these types of videos with Angular and RxJS out there and you are providing a great service to the community with your videos and clear real world explanations!! Keep up the great work

Fantastic presentation! You definitely helped to clear the air with the differences between switchMap, concatMap, and mergeMap! Truly appreciate the effort here!

Great explanation as always! The operators you showed are indeed those that we also use the most on our projects.
I will share the link to this video with my colleagues who are still kinda new to RxJs so they can watch and learn at their own pace 🙂
