React Native Deployment

Priority: P2 (MEDIUM)

Workflow: Ship Production Release with EAS Build

1. Configure eas.json with development, preview, and production profiles
2. Set environment variables in .env.production
3. Run eas build --platform all --profile production
4. Verify build artifact on EAS dashboard
5. Submit to stores: eas submit --platform ios / eas submit --platform android
6. For JS-only hotfixes, publish OTA: eas update --branch production

Over-the-Air (OTA) Updates

CodePush (Microsoft)

• JS-Only Updates: Update JS bundle without app store review.
• Staging/Production: Use separate deployments.
• Install: npm install react-native-code-push
• Limitations: Cannot update native code (Obj-C, Java, Swift, Kotlin).

Expo Updates

• Expo Projects: Built-in OTA updates via channels (dev, staging, prod).
• Install: expo install expo-updates

Build Configurations

Expo (EAS Build)

See deployment reference for EAS build profile configuration and CLI commands.

React Native CLI

• Android: Use productFlavors in build.gradle (dev, staging, prod).
• iOS: Use Xcode schemes.
• Fastlane: Automate builds and uploads (fastlane ios release).

Environment Management

• react-native-config: .env files for API URLs, keys.
• Separate Configs: .env.dev, .env.staging, .env.production.

Anti-Patterns

• No OTA for Native Changes: Requires store release.
• No Secrets in Code: Use .env & CI secrets.
• No Manual Builds: Automate with CI/CD.
