ReactXP
Library for cross-platform app development
... to this abstraction, you can share your view definitions, styles and animations across multiple target platforms. Of course, you can still provide platform-specific UI variants, but this can be done selectively where desired. ReactXP is designed with cross-platform development in mind. In general, it exposes APIs, components, props, styles and animation parameters that are implemented in a consistent way across React JS (HTML) and React Native for iOS and Android.
