Out-of-Tree Platforms

React Native is not only for Android and iOS devices - our partners and the community maintain projects that bring React Native to other platforms, such as:

From Partners

• React Native macOS - React Native for macOS and Cocoa.
• React Native Windows - React Native for Microsoft's Universal Windows Platform (UWP).

From Community

• React Native tvOS - React Native for Apple TV and Android TV devices.
• React Native Web - React Native on the web using React DOM.
• React Native Skia - React Native using Skia as a renderer. Currently supports Linux and macOS.

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 npx 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.
