How did the whole idea to create React start and how many people worked on developing and implementing it at Facebook initially?

Hi Rem, Do you have any productivity hacks that you can recommend? Also do you actively write Node.js apps these days?

I have the following questions : What types of apps should use MobX for state management? What types of apps shouldn't use MobX? Thanks for this AMA. :)

I also wonder about the same. May be worth asking this as a question here? :D

I used to write integration tests for only 20% of the code. Sure, I write a lot of unit tests but integration tests are a different ball game altogether. The amount of time and energy that you have to put through to design integration tests IMHO is not worth it. I rely on the combination of unit test + manual checks, maybe I can run away with it because I have never worked on such a scale project!

I don't think so, at least not soon enough.I definitely see bots automating a lot of stuff that we do through utility web apps but they will always be a complimentary feature not a substitute.

There is no better/worse way to do it. It all depends on your strengths, if you know ES6, go with plain classes, or else React.createClass is good as well. However, considering that ES6 will be standard in near future, I would recommend you go with plain classes.

NodeJs is a good option coupled with frameworks like angular or react/flux in frontend. However, I feel meteor has lots of black magic and I haven't really heard a real big app being built in meteor so I would avoid meteor in this case.

I am still unsure why the entire Node ecosystem depended on this package. It barely takes two mins to write this function yourself. Any ideas? @fibric @Kleo @rajkumarpb @aniforprez @cliffrowley ?

Spot on buddy!!
