Build OS X desktop apps using React Native and Cocoa.
<View>
<Button onClick={() => alert('clicked')} />
</View>
$ npm install react-native-desktop-cli -g
$ react-native-desktop init MyProject
$ cd MyProject
$ open osx/MyProject.xcodeproj
Since it's simply just a fork, you can follow the same instruction on facebook.github.io/react-native.
Disclaimer. Having previous experience with React Native highly recommended. There is no success story for any RN desktop app yet, so it's not proven by production use.
Feel free to ask anything on #react-native-desktop
channel if you run into problems (and you probably will).
