Deployment This skill covers deploying Expo applications across all platforms using EAS (Expo Application Services). References Consult these resources as needed: ./references/workflows.md -- CI/CD workflows for automated deployments and PR previews ./references/testflight.md -- Submitting iOS builds to TestFlight for beta testing ./references/app-store-metadata.md -- Managing App Store metadata and ASO optimization ./references/play-store.md -- Submitting Android builds to Google Play Store ./references/ios-app-store.md -- iOS App Store submission and review process Quick Start Install EAS CLI npm install -g eas-cli eas login Initialize EAS npx eas-cli@latest init This creates eas.json with build profiles. Build Commands Production Builds

iOS App Store build

npx eas-cli@latest build -p ios --profile production

Android Play Store build

npx eas-cli@latest build -p android --profile production

Both platforms

npx eas-cli@latest build --profile production Submit to Stores

iOS: Build and submit to App Store Connect

npx eas-cli@latest build -p ios --profile production --submit

Android: Build and submit to Play Store

npx eas-cli@latest build -p android --profile production --submit

Shortcut for iOS TestFlight

npx testflight Web Deployment Deploy web apps using EAS Hosting:

Deploy to production

npx expo export -p web npx eas-cli@latest deploy --prod

Deploy PR preview

npx eas-cli@latest deploy EAS Configuration Standard eas.json for production deployments: { "cli" : { "version" : ">= 16.0.1" , "appVersionSource" : "remote" } , "build" : { "production" : { "autoIncrement" : true , "ios" : { "resourceClass" : "m-medium" } } , "development" : { "developmentClient" : true , "distribution" : "internal" } } , "submit" : { "production" : { "ios" : { "appleId" : "your@email.com" , "ascAppId" : "1234567890" } , "android" : { "serviceAccountKeyPath" : "./google-service-account.json" , "track" : "internal" } } } } Platform-Specific Guides iOS Use npx testflight for quick TestFlight submissions Configure Apple credentials via eas credentials See ./reference/testflight.md for credential setup See ./reference/ios-app-store.md for App Store submission Android Set up Google Play Console service account Configure tracks: internal → closed → open → production See ./reference/play-store.md for detailed setup Web EAS Hosting provides preview URLs for PRs Production deploys to your custom domain See ./reference/workflows.md for CI/CD automation Automated Deployments Use EAS Workflows for CI/CD:

.eas/workflows/release.yml

name : Release on : push : branches : [ main ] jobs : build-ios : type : build params : platform : ios profile : production submit-ios : type : submit needs : [ build - ios ] params : platform : ios profile : production See ./reference/workflows.md for more workflow examples. Version Management EAS manages version numbers automatically with appVersionSource: "remote" :

Check current versions

eas build:version:get

Manually set version

eas build:version:set -p ios --build-number 42 Monitoring

List recent builds

eas build:list

Check build status

eas build:view

View submission status

eas submit:list
