React.js Conf 2015 Keynote 2 - A Deep Dive into React Native

[@ciryon666]

Seen from the perspective of someone who has coded iOS apps since 2009 I'm hugely impressed. This brings the development speed and ergonomics from the web world to native, without compromising with UX. Christopher ported Flexbox to native in two weeks using manual genetic programming?! Insane.

[@tamal]

As a native developer, I'm very, very impressed. Much better than PhoneGap/Cordova and web view stuff. I hope Facebook and dev communities will catch up to new SDKs/APIs that Apple introduces in WWDC and later and enhance #ReactNative quickly. It'll be great if Apple devs also contribute to this. All the best! #ReactJSConf

[@AnkitDuseja]

"If you got an exception, we are not going to hide it like your console always does, we are going to show it in your face!" #epic moment :D

[@BrunoBerisso]

This is very nice but i have some doubts: - What happen with battery life running a JS engine in parallel? - What about memory management (on both sides; JS and ObjC)? - Animations?

[@deniskatinas]

Flexbox and React are great, but the example at 16:55 is super simple with basic CSS 2.1 using two rules, same as in flexbox: jsfiddle.net/kufd1a0g/.

[@sschengyf]

Fabulous. A great thing for web developer to make mobile apps.

[@conw_y]

OMG. ReactJS making better dev tools than Apple!

[@nbkmundotech]

React Native é muito, muito legal!!!! Para quem quiser aprender mais sobre o React Native, usando o ES6, eu fiz uns vídeos no meu canal.

[@conw_y]

11:05 Circularity. ReactJS is bringing back inline styles from the dead. Haha. The more things change, the more they stay the same.

[@ERANOR]

The problem is JavaScript runs on a browser's main thread. CSS animations enable browsers to run operations on new threads and create different layers, which are separated from everything else happening on the main thread. In other words, while your main UI thread will be in heavy use, JavaScript animations might freeze although CSS animations will continue to work. So As the first part of React presentation said that React doesn't run on the main thread, So my question is how the browser manage the css layer if it run inside React thread.

[@xanderbanter3752]

This is awesome...I love this idea :) Can't wait for Android support so I can start playing.

[@kimjisena]

whoa...to think this is how it started react native did win in the end.

[@phil-l]

Would be nice if someone could provide instruction to setup Atom, xcode and the file watcher

[@oeb25]

What is that text editor? It says "Arsenal" at the top left, but I can't seem to find any editors with that name!

[@augre-app]

Atom

[@JoeyClover]

The statements about AutoLayout are incorrect. Autocorrect does allow multi-line text and you don't have to provide it with all 4 values. It just needs to make sense.

[@andrelip1]

So its basically a Titanium rework?

[@nolin8790]

I'm using the scrollView and I want to get the value of contentInset, is anybody having the same experience? Any answer is welcome! Thank you!

[@BrentLagerman]

Is there any roadmap for when Android will be released? Inquiring minds want to know...

[@KemalAhmedIsAwesome]

Apparently this September it'll be released

[@Rockstar-dm6ok]

please provide further support of react native i m more frustrated with flutter in 2022 i more believe in javascript rather than any other programming languagae because it is ease to use

[@Weq5ter]

This would be good if i could write a single view to be portable to all OS's

[@cobetienca]

no offense, but it's really hard for me to understand what he's talking about, can you embedded subtitle? :(

[@505KP]

Yeah, use this guy for the French version, no problem, but for English, get a native speaker.

[@naomipunkclan]

kpublik narrow minded

[@505KP]

Paul Mackinnon balding

[@naomipunkclan]

kpublik this comment says it all. You troll.

[@505KP]

Paul Mackinnon Just demonstrating the amount of intelligent thought you put into your original comment.

[@王宁-z4k]

非常好！ 努力跟上大神的脚步

[@VinceYuan]

One of the problems of using React Native in the app is it is difficult to protect the source code (javascript)

[@gorillapimpin2978]

you can't hide Android apps either. You can get away with obfusticating it but its never impossible to reverse engineer your app.

[@gnack420]

Your source code is almost never doing anything particularly special or revolutionary, it's the functionality and design of the app as a whole that decides whether it succeeds or fails.

[@loquek]

***** what are you trying to hide? :-)

[@saulobmv]

what is the difference between this and PhoneGap?

[@piterwilson]

PhoneGap runs on a webview "... The app executes as a WebView within the native application wrapper, which you distribute to app stores...." docs.phonegap.com/en/4.0.0/guide_overview_index.md.html

[@bzhmaddog]

He says 'like' as many times as Steeve Jobs says 'Amazing'

[@jasonfrazzano]

Why not just put a style tag and a string literal for the whole thing?

[@fahtihi]

Now is a good time to go Hybrid

[@pascalbrewing1189]

fucking awesome

[@RyanLikeU]

Nice job.

[@dortzur90]

WOWOWOWWOWOWO!!!!!!!!!!!!!!

[@tunavargi64]

I would like to buy a hamburger

[@CarlosGomesCabral]

+Tuna VARGI hahahahahahaha

[@robertbain6792]

Still need a Mac to develop iOS apps. 1984 commercial from Apple, yeah, you're the oppressive regime now, Apple.

[@ahmedrebai6042]

very nice technology , #react-native

Why I'm disappointed in React Native The web development Holy Grail right now is to compete directly with (perhaps someday replace) native mobile applications. With React Native the web has lost a huge partner in Facebook for helping make this a reality. What incentive does Facebook have for pushing forward mobile web now that they can just produce native applications with web technology? What incentive do the existing React developers (and the large number of developers that will move to React in the near future) have for building and proving out mobile web use-cases with React Native? None. reefpoints.dockyard.com/2015/01/30/why-i-am-disappointed-in-react-native.html
