EAS (Expo Application Services) Deployment Patterns
Expo Application Services (EAS) deployment pattern library for React Native and Expo apps — EAS Build for iOS and Android native builds in the cloud, EAS Submit for App Store Connect and Google Play Console uploads, EAS Update for OTA updates without app store review (shipping JavaScript fixes in hours instead of days), eas.json build profiles (development / preview / production), credentials management (Apple certificates, provisioning profiles, keystores), environment variables per profile, build caches, internal distribution via Ad-Hoc or TestFlight Internal Testing, monorepo support with workspaces, and integration with CI (GitHub Actions). Use when building or deploying a React Native / Expo app to iOS or Android, configuring build profiles, managing signing credentials, pushing OTA updates, or automating mobile deployment via CI. Differentiates from platform-specific skills (deploy-app-store, deploy-play-store) by covering the build pipeline, not the store submission workflow.
