Deployment

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

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
