RxJS In-Depth – Ben Lesh

[_benlesh]

I paired on the source code with Jeff Cross and Rob Wormald for their talk and mine. It can be found here:

I think around 15:00 there's a mistake. He says "if you tell it to stop producing values, that's the producer telling the consumer it knows it's done, so the completion handler won't fire. The completion handler is for when the producer wants to tell the consumer that it's done successfully".

I would swap the order producer<=>consumer the first time it appears for it to make sense. When calling unsubscribe it's the consumer telling the producer "I don't care", so the completion handler is not fired (I think).

Fantastic explanation of Observables! Thanks!

Awesome talk. Thinking in Rx has been challenging, so these videos help a ton.

Great presentation and comparison of promises vs observables. Plus the honesty in the final advice on not believing in any zero drawback technology :) Thanks !

Good talk. I need to practice rxjs alot before everything goes down my head...

I think the term "set" is misleading, and "stream" is definitely the proper term here. The values you get from an Observable are ordered, and not necessarily unique.

Good talk, though.

I wonder if this technology could be applied to HTML5 videos. This could allow a good way to "stop downloading" the videos, and reconnecting in case there's a problem.

Anyone know if they'll add in Rx.Subject class to Angular 2?

What presentation tool did he use to create these animations or text greying out? You can see an example of animation around 9.42

介绍 filter map reduce 的时候，比较了 数组操作和流操作的不同

If that was in depth, I'd hate to see a summary version.

Any idea which is the editor he's using?
