# 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

```bash
npm install -g eas-cli
eas login
```

### Initialize EAS

```bash
npx eas-cli@latest init
```

This creates `eas.json` with build profiles.

## Build Commands

### Production Builds

```bash
# 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

```bash
# 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:

```bash
# 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:

```json
{
  "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:

```yaml
# .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"`:

```bash
# Check current versions
eas build:version:get

# Manually set version
eas build:version:set -p ios --build-number 42
```

## Monitoring

```bash
# List recent builds
eas build:list

# Check build status
eas build:view

# View submission status
eas submit:list
```

# Expo Deployment


## Overview

Deploy Expo applications to production environments, including app stores and over-the-air updates.


## When to Use This Skill

Use this skill when you need to deploy Expo apps to production.

Use this skill when:
- Deploying Expo apps to production
- Publishing to app stores (iOS App Store, Google Play)
- Setting up over-the-air (OTA) updates
- Configuring production build settings
- Managing release channels and versions


## Instructions

This skill provides guidance for deploying Expo apps:

1. **Build Configuration**: Set up production build settings
2. **App Store Submission**: Prepare and submit to app stores
3. **OTA Updates**: Configure over-the-air update channels
4. **Release Management**: Manage versions and release channels
5. **Production Optimization**: Optimize apps for production


## Deployment Workflow


### Pre-Deployment

1. Ensure all tests pass
2. Update version numbers
3. Configure production environment variables
4. Review and optimize app bundle size
5. Test production builds locally


### App Store Deployment

1. Build production binaries (iOS/Android)
2. Configure app store metadata
3. Submit to App Store Connect / Google Play Console
4. Manage app store listings and screenshots
5. Handle app review process


### OTA Updates

1. Configure update channels (production, staging, etc.)
2. Build and publish updates
3. Manage rollout strategies
4. Monitor update adoption
5. Handle rollbacks if needed


## Best Practices

- Use EAS Build for reliable production builds
- Test production builds before submission
- Implement proper error tracking and analytics
- Use release channels for staged rollouts
- Keep app store metadata up to date
- Monitor app performance in production
