Development	Local development	Internal	`development`
Staging	Pre-production testing	Internal	`staging`
Production	Live app releases	Store	`production`

Development Workflow

1. Feature Development

# Create feature branch
git checkout -b feature/new-authentication

# Start development server
pnpm start

# Make changes and test locally
pnpm test
pnpm lint

# Commit changes
git add .
git commit -m "feat: add biometric authentication"
git push origin feature/new-authentication

2. Testing & QA

# Run full test suite
pnpm test:all

# Build for staging
eas build --profile staging --platform all

# Deploy OTA update for testing
eas update --branch staging-branch --message "Feature testing"

3. Release Process

# Update version
npm version minor

# Create release tag
git tag v1.2.0
git push origin v1.2.0

# Automated process will:
# - Build production app
# - Submit to app stores
# - Deploy OTA update
# - Create GitHub release

CI/CD Pipeline

Automated Workflows

Quality Checks (on every push/PR)
- TypeScript type checking
- ESLint code quality
- Unit and integration tests
- E2E testing on Android
Preview Builds (on hotfix branches)
- Quick EAS updates for testing
- PR preview links
- Staging channel deployment
Release Automation (on git tags)
- Production builds
- App store submission
- GitHub release creation
- OTA update deployment

Monitoring & Analytics

Build Status: EAS Dashboard
App Performance: Expo Analytics
Crash Reporting: App Store Connect / Google Play
User Analytics: Custom analytics integration

Best Practices

Code Quality

TypeScript: Strict type checking enabled
ESLint: Comprehensive linting rules
Prettier: Consistent code formatting
Husky: Pre-commit hooks for quality checks

Testing Strategy

Unit Tests: Component and utility testing
Integration Tests: API and navigation flows
E2E Tests: Critical user journeys
Manual Testing: Device-specific validation

Performance

Bundle Size: Monitor and optimize app size
Memory Usage: Profile and fix memory leaks
Startup Time: Optimize app launch performance
Network: Efficient API calls and caching

Security

Environment Variables: Secure credential management
API Security: Proper authentication and authorization
Data Protection: Secure local storage
Code Obfuscation: Production build security

Troubleshooting

Common Development Issues

Metro Bundler Issues

# Clear Metro cache
pnpm start --clear

# Reset Metro bundler
npx react-native start --reset-cache

Build Failures

# Clear EAS cache
eas build --clear-cache

# Check build logs
eas build:list --limit 5
eas build:view <build-id>

OTA Update Problems

# Check channel configuration
eas channel:list

# Verify update deployment
eas update:list --branch production-branch

# Rollback if needed
eas update:rollback --branch production-branch
