# expo-dev-launcher

`expo-dev-launcher` is an npm package installable in any Expo or React Native project. Once installed, any Debug builds of your application will gain the ability to load projects from Expo CLI. Release builds of your application will not change other than the addition of a few header files. This package is intended to be included in your project through [`expo-dev-client`](https://docs.expo.dev/versions/latest/sdk/dev-client/).

## Documentation

You can find more information in the [Expo documentation](https://docs.expo.dev/develop/development-builds/introduction).

## Contributing

The Dev Launcher UI is built with native platform UI toolkits:

- **iOS**: SwiftUI (see `ios/SwiftUI/`)
- **Android**: Jetpack Compose (see `android/src/debug/java/expo/modules/devlauncher/compose/`)

Local development is usually done through [`bare-expo`](/apps/bare-expo). Recompile `bare-expo` after making changes to the native code.
