Expo modules are configured in **expo-module.config.json**. This file currently is capable of configuring autolinking and module registration. The following properties are available:

-   `platforms` — An array of supported platforms. Acceptable values are `android`, `apple` (or use the more granular `ios` / `macos` / `tvos`), `web` and `devtools` (see [Create a dev tools plugin](/debugging/create-devtools-plugins)).
-   `apple` — Config with options specific to Apple platforms
    -   `modules` — Names of Swift native modules classes to put to the generated modules provider file.
    -   `appDelegateSubscribers` — Names of Swift classes that hook into `ExpoAppDelegate` to receive AppDelegate lifecycle events.
-   `android` — Config with options specific to Android platform
    -   `modules` — Full names (package + class name) of Kotlin native modules classes to put to the generated package provider file.
