RxJS in Action

Overall this is a very comprehensive book about the Rx.js. I was already familiar with functional programming knowing Haskell. There is very little cruft -- especially excluding a bit of hyperbole about "Testing is inherently built into functional programs." You'll learn a bit about a Pouch DB, a bit about Websockets, and a bit about React (a chapter I didn't much value).All in all, I feel like I have a great foundation in Rx.js. I saw it being used in Angular and it set me back and had me saying "need to learn that." Now I've got a good foundation.A few questionable examples, and I'm rounding up to the nearest star. =)

Why is every book on RxJS written by people more interested in smelling their own farts than clearly and concisely explaining the technology to a professional audience?“RxJS In Action” is a meandering text with no respect its audience. Writing style aside (which is as infuriatingly verbose as it is oddly worded) the book contains half the information as volumes 1/4th its page count.Skip it.“Well Mike, you unsettlingly handsome devil, what should I read to learn RxJS?” Good question. Unfortunately there are no good books on the subject. Buy any of them and by the time you’re done gawking at the ridiculous diagrams and playing with stupid marble toys online, you’re going to have to rip open the source to figure out wtf is going on, just like everyone else.Seriously, just read the source code. RxJS is a beautiful piece of technology that’s being held hostage by a faux-academic cult determined to make any writing about RxJS either a baffling oversimplification or an inscrutable pseudo-treatis on a dozen unrelated topics and the philosophy of the <WHATEVER> operator, oh yeah, and how it relates to Kant or some nonsense. At what point between a Masters and a PhD do they extract your ability to communicate with other human beings? I really want to know.Every book has some insane example project (a game in RxJS!) but few cover the implementation of custom operators. OperatorFunction<T, R>? Nope. Here’s a few dozen scraps of high-level sample code that look nothing like anything you’ll need to write in production.Books like “RxJS In Action” make me hate my job.

This book is not for beginners, it assumes knowledge of functional programming (e.g. lodash/Ramda) or functional reactive programming such as RxJava/BaconJs. That said, I highly recommend it to anyone doing a lot of work with Angular 2 since RxJs integral part of the framework. If you are a senior javascript engineer, then you have to read it.

I learned a lot about RxJS. Definitely a good read

Very good and informative introduction to RxJS. If you are new to Javascript Function Reactive paradigm , this is a must read.

Loads of text to explain some high-level ideas, the author ignores the fact that the abstract idea comes from coding. I am not that experienced to reflect if rxjs is good or not, I not to one who tends to create the spec for rxjs. All I what is what is some tricks for rxjs.In a nutshell, the author put too much irrelevant stuff and ignore the core

I've got also Rx.NET in Action and I wanted to have a deeper understanding of the library used in a javascript environment. Well actually as I'm also experimenting angular 5 I wanted to master better observable and observable operators. This book is very complete with so many good examples and best practices. Highly recommended.

Update: 10.10.2020This book is from 2017 but is still up to date. The learning curve is very high but it is worth to learning. It makes life a lot easier when you develop with rxjs. Thanks to the author. He did a great job with this book.
