This is great, but I was wondering if react-native-file-upload provided any improvements over the functionality provided in React Native proper, and if so, what. A few months ago I polyfilled XMLHttpRequest and FormData so that file upload scenarios should be possible, on both iOS and Android. Check out https://github.com/facebook/react-native/blob/fe42a28de12926c7b3254420ccb85bef5f46327f/Examples/UIExplorer/XHRExample.ios.js#L215-L230 for instance.

If there is anything that's missing from React Native, I'd love to hear about it. It'd be great to get those features into React Native. Thanks!
