Expo is an open-source platform for making universal native apps that run on Android, iOS, and the web. It includes a universal runtime and libraries that let you build native apps by writing React and JavaScript. This repository is where the Expo client software is developed, and includes the client apps, modules, apps, and more. The Expo CLI repository contains the Expo development tools.

🗺 Project Layout

  • packages All the source code for the Unimodules, if you want to edit a library or just see how it works this is where you'll find it.
  • apps This is where you can find Expo projects which are linked to the development Unimodules. You'll do most of your testing in here.
  • docs The source code for https://docs.expo.io
  • templates The template projects you get when you run expo start
  • react-native-lab This is our fork of react-native. We keep this very close to the upstream but sometimes need to add quick fixes locally before they can land.
  • guides In-depth tutorials for advanced topics like contributing to the client.
  • android contains the Android project.
  • home contains the JavaScript source code of the app.
  • ios contains the iOS project.
  • ios/Exponent.xcworkspace is the Xcode workspace. Always open this instead of Exponent.xcodeproj because the workspace also loads the CocoaPods dependencies.
  • tools contains build and configuration tools.
  • template-files contains templates for files that require private keys. They are populated using the keys in template-files/keys.json.
  • template-files/ios/dependencies.json specifies the CocoaPods dependencies of the app.
