Pre-release version of the Expo development launcher package for testing.
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.
You can find more information in the Expo documentation.
The expo-dev-launcher repository consists of two different parts, the exported package, which includes the native functions, located in the android, ios and src folders and the Dev Launcher interface, located under the bundle folder.
Local development is usually done through bare-expo.
