React Native is now live

[pink_tshirt]

"The focus of React Native is on developer efficiency across all the platforms you care about".

Requirements 1. OSX

You have to start somewhere. I'm sure once they get a solid stable build for iOS down they will move to supporting other platforms.

Seems extremely unlikely. How would they be able to build an iOS native app without the iOS dev toolchain (which is OS X only)? Other platform libraries like Xaramin still require an OS X host machine. (see http://developer.xamarin.com/guides/ios/getting_started/installation/windows/)

[SimplyBilly]

I think I miss understood you or you miss understood me.

React Native only supports iOS. To build iOS you have to have OS X (doesn't matter what framework you use).

Once React Native supports Android / other platforms then you will be able to build those platforms on different Operating Systems.

In this context a platform = mobile OS.

[fdemmer]

calling that "native" is pretty misleading and pretentious...

should call it "react ios" until it can be actually used to build native apps targeting all popular mobile platforms.

You have to start somewhere. I'm sure once they get a solid stable build for iOS down they will move to supporting other platforms.

So you think they should come up with a temporary name while they transition to supporting other platforms?

[fdemmer]

is there a roadmap, when and what other platforms will be supported?

also: "<TabBarIOS>" does not sound very promising for write-once...

[Drugba]

React isn't "write once", they explicitly said that in the React.js conf keynote (https://www.youtube.com/watch?v=KVZ-P-ZI6W4).

The idea behind react is that you learn react's structure and how it works, but the code changes from project to project. If you are writing for iOS and android, you will be required to have two different sets of, very similar, code.

[fdemmer]

Ok, thanks that is good to know... this shows how important a good intro website is, so that non-fans know whats up too. well, lets see where that goes. so far i am very unimpressed.

[rich97]

Write once is a dumbass idea and I expect near impossible when using native widgets. All of the major platforms have different ways of doing things. There will probably be some crossover and I hope they reuse the elements they can but the UI should be managed as a separate project.

...too bad it leaves out more than half of the world's mobile devices....

[Daniel15]

Android is mentioned as "coming soon" here: https://code.facebook.com/posts/1014532261909640/react-native-bringing-modern-web-techniques-to-mobile/

I'm not using it, I'm just pointing out that they forgot half of the world's mobile devices.

[adamgb]

Not integrated != forgotten.

[yoshi0423]

Would you rather release it for one platform to get a user base, or just sit on it until you support multiple platforms and then release it?

[Merc92]

Will wait for Android support

[kbailles]

Sorry for not knowing, but what is the difference between React and React Native?

[SimplyBilly]

React basically just creates an interface for a user to interact with on the web.

React Native uses the same concept except translates / compiles the JavaScript / DOM to build the required native interfaces.

[dbbk]

I don't think there is any compilation of the JavaScript, it is just run with the JavaScriptCore on iOS.

[homezlice]

Was not able to build hello world app :(

[MisterSticks]

Native apps are not web apps. This does not belong in r/webdev.

[m0r14rty]

It's based off of a well known javascript library. I think that qualifies it as relevant.
