Expo Application Services
API Reference

EAS Build

EAS Build is a hosted service for building app binaries for your Expo and React Native projects.
It makes building your apps for distribution simple and easy to automate by providing defaults that work well for Expo and React Native projects out of the box, and by handling your app signing credentials for you (if you wish). It also makes sharing builds with your team easier than ever with internal distribution (using ad hoc and/or enterprise "universal" provisioning), deeply integrates with EAS Submit for app store submissions, and has first-class support for the expo-updates library.
It's the next generation of the expo build:[ios/android] command — designed to work for any native project, whether or not you also use the managed workflow. It's the fastest way to get from npx create-expo-app, expo init or npx react-native init to app stores.

Learning about the limitations

EAS Build is a new and rapidly evolving, so we recommend getting familiar with the current limitations.
