React Native Deployment

React Native Deployment

Priority: P2 (MAINTENANCE)

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 Projects: Built-in OTA updates via channels (dev, staging, prod).

• Install: expo install expo-updates

Build Configurations

Expo (EAS Build)

{
  "build": {
    "development": { "developmentClient": true },
    "preview": { "distribution": "internal" },
    "production": { "autoIncrement": true }
  }
}

eas build --platform ios --profile production

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.
