A library for building cross-platform apps

  • With React and React Native, your web app can share most its logic with your iOS and Android apps, but the view layer needs to be implemented separately for each platform.
  • We have taken this a step further and developed a thin cross-platform layer we call ReactXP.
  • If you write your app to this abstraction, you can share your view definitions, styles and animations across multiple target platforms.
  • 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.
  • A few platform-specific props and style attributes have been exposed, but we have tried to keep these to a minimum.


The authors of React use the phrase “learn once, write anywhere”. With React and React
Native, your web app can share most its logic with your iOS and Android apps, but the view
layer needs to be implemented separately for each platform. We have taken this a step further
and developed a thin cross-platform layer we call ReactXP. If you write your app 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.


@Vjeux: I designed React Native APIs to be x-platform: iOS, Android, web and others. So glad Microsoft is making it real!

Share most of your code between the web, iOS, Android, and Windows.

Create great-looking, responsive web pages and mobile apps that feel native.

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. A few platform-specific props and style attributes have been exposed, but we have tried to keep these to a minimum.

ReactXP is meant to be as lightweight as possible. The “core” components and APIs are limited to the functionality required for almost all applications. Extensions to ReactXP expose more specialized functionality in a similar cross-platform manner.
