Introduction

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 includes the Expo SDK, Modules API, Go app, CLI, Router, documentation, and various other supporting tools. Expo Application Services (EAS) is a platform of hosted services that are deeply integrated with Expo open source tools. EAS helps you build, ship, and iterate on your app as an individual or a team.

Read the Expo Community Guidelines before interacting in the repository. Thank you for helping keep the Expo community open and welcoming!

🗺 Project Layout

• packages All the source code for Expo modules, 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 modules. You'll do most of your testing in here.
• apps/expo-go This is where you can find the source code for Expo Go.
• apps/expo-go/ios/Exponent.xcworkspace is the Xcode workspace. When developing iOS, always open this instead of Exponent.xcodeproj because the workspace also loads the CocoaPods dependencies.
• docs The source code for https://docs.expo.dev
• templates The template projects you get when you run npx create-expo-app
• react-native-lab This is our fork of react-native used to build Expo Go.
• guides In-depth tutorials for advanced topics like contributing to the client.
• tools contain 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.
