Deployment

When to Use

Use this skill when you need deploy Expo apps to production with EAS — build and submit to the iOS App Store, Google Play Store, and TestFlight, configure eas.json build and submit profiles, manage app versions and build numbers, publish App Store metadata and ASO, and deploy web bundles and API routes via EAS...

This skill covers deploying Expo applications across all platforms using EAS (Expo Application Services).

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

Expo Router API routes deploy together with the web bundle on EAS Hosting — eas deploy ships both. To author or configure the API routes themselves, use the expo-api-routes skill.

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 ./references/testflight.md for credential setup
See ./references/ios-app-store.md for App Store submission

Android

Set up Google Play Console service account
Configure tracks: internal → closed → open → production
See ./references/play-store.md for detailed setup

Web

EAS Hosting provides preview URLs for PRs
Production deploys to your custom domain
See ./references/workflows.md for CI/CD automation

Automated Deployments

EAS Workflows automate the build → submit → update → deploy pipeline for CI/CD. See ./references/workflows.md for deployment-oriented examples. To author or validate workflow YAML, use the expo-cicd-workflows skill — it works from the live workflow schema.

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

Limitations

Use this skill only when the task clearly matches its upstream product or API scope.
Verify commands, API behavior, pricing, quotas, credentials, and deployment effects against current official documentation before making changes.
Do not treat generated examples as a substitute for environment-specific tests, security review, or user approval for destructive or costly actions.
