React Native vs ReactXP: What are the differences?
What is React Native? A framework for building native apps with React. React Native enables you to build world-class application experiences on native platforms using a consistent developer experience based on JavaScript and React. The focus of React Native is on developer efficiency across all the platforms you care about - learn once, write anywhere. Facebook uses React Native in multiple production apps and will continue investing in React Native.
What is ReactXP? A library for cross-platform app development using React and React Native, by Microsoft.
With React and React Native, your web app can share most of 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.
React Native and ReactXP are primarily classified as "Cross-Platform Mobile Development" and "Cross-Platform Mobile" tools respectively.
React Native and ReactXP are both open source tools. React Native with 78.8K GitHub stars and 17.6K forks on GitHub appears to be more popular than ReactXP with 7.77K GitHub stars and 548 GitHub forks.
