Out-of-Tree Platforms

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

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.

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.
