expo-workflows

CI/CD pipelines with GitHub Actions automate Expo app builds and updates by triggering workflows on code changes. Configure GitHub Actions workflows to run EAS Build for iOS and Android, manage environment variables, and deploy OTA updates via EAS Update, eliminating manual build steps and reducing deployment time.

EAS Build profiles are defined in eas.json and specify build settings for iOS and Android environments. Create separate profiles for development and production to standardize build configuration, manage dependencies, set environment variables, and ensure consistent builds across team members.

OTA updates via EAS Update deliver app changes without app store resubmission by pushing updates to connected devices. Configure expo-updates in your project, push updates through EAS Update, and users receive changes automatically on next app launch, accelerating iteration cycles.

Environment variables are managed through eas.json configuration and GitHub Actions secrets, automating setup across managed and bare Expo workflows. This standardizes configuration deployment, prevents manual errors, and ensures consistent environment setup for builds and OTA updates.

eas.json is the central configuration file required for both iOS and Android builds with EAS Build. It defines build profiles, environment variables, credentials, and platform-specific settings, enabling consistent automated builds across both platforms from a single configuration.
