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
