Out-of-Tree Platforms

React Native is not only for Android and iOS - there are community-supported projects that bring it to other platforms, such as:

• React Native Windows - React Native support for Microsoft's Universal Windows Platform (UWP) and the Windows Presentation Foundation (WPF)
• React Native DOM - An experimental, comprehensive port of React Native to the web. (Not to be confused with React Native Web, which has different goals)
• React Native Turbolinks - React Native adapter for building hybrid apps with Turbolinks 5.
• React Native Desktop - A project aiming to bring React Native to the Desktop with Qt's QML. A fork of React Native Ubuntu, which is no longer maintained.
• React Native macOS - An experimental React Native fork targeting macOS and Cocoa
• React Native tvOS - adaptation of React Native for Apple tvOS
• alita - An experimental, comprehensive port of React Native to mini-program(微信小程序).

Creating your own React Native platform

Right now the process of creating a React Native platform from scratch is not very well documented - one of the goals of the upcoming re-architecture (Fabric) is to make maintaining a platform easier.

Bundling

As of React Native 0.57 you can now register your React Native platform with React Native's JavaScript bundler, Metro. This means you can pass --platform example to react-native bundle, and it will look for JavaScript files with the .example.js suffix.

To register your platform with RNPM, your module's name must match one of these patterns:

• react-native-example - It will search all top-level modules that start with react-native-
• @org/react-native-example - It will search for modules that start with react-native- under any scope
• @react-native-example/module - It will search in all modules under scopes with names starting with @react-native-

You must also have an entry in your package.json like this:

{

"rnpm": {

"haste": {

"providesModuleNodeModules": ["react-native-example"],

"platforms": ["example"]

}

}

}

"providesModuleNodeModules" is an array of modules that will get added to the Haste module search path, and "platforms" is an array of platform suffixes that will be added as valid platforms.
