> React Native Notes by Rishabh - Topic 20

### 1. Fastlane Mobile Automation (`Fastfile`) 🏎️

Ruby-based mobile automation standard jo code signing, building, screenshot generation, aur App Store uploads automate karta hai:

```ruby
# fastlane/Fastfile
default_platform(:ios)

platform :ios do
  desc "Push a new beta build to Apple TestFlight"
  lane :beta do
    setup_ci
    match(type: "appstore", readonly: true) # Automated git-based code signing
    increment_build_number(xcodeproj: "RishabhKaksha.xcodeproj")
    build_app(workspace: "RishabhKaksha.xcworkspace", scheme: "RishabhKaksha")
    upload_to_testflight(skip_waiting_for_build_processing: true)
  end
end
```

### 2. EAS Build Cloud Matrix Configuration (`eas.json`)

```json
{
  "cli": { "version": ">= 10.0.0" },
  "build": {
    "production": {
      "ios": { "simulator": false },
      "android": { "buildType": "app-bundle" },
      "env": { "APP_ENV": "production" }
    }
  },
  "submit": {
    "production": {
      "android": { "serviceAccountKeyPath": "./google-service-key.json" },
      "ios": { "appleId": "rishabh@boostengine.in", "ascApiKeyPath": "./AuthKey.p8" }
    }
  }
}
```

### 3. Master Comparison Matrix

### 4. Interview Ke 3 Sawal Is Topic Se

1. **Android App Bundle (`.aab`) `.apk` se behtar kyu hai?** -> Google Play Dynamic Delivery use karke user ke specific device architecture (CPU, Screen density, Language) ke anusaar compressed custom APK serve karta hai (Saves 35% download size).
2. **`fastlane match` (Fastlane Match Git Sync) kya karta hai?** -> Team ke saare iOS developers aur CI machines ke beech certificates aur provisioning profiles ko private encrypted Git repo me sync rakhta hai.
3. **Internal Testing vs Closed Testing vs Production in Google Play Console me kya difference hai?** -> Internal Testing instant download link deti hai (Up to 100 testers); Closed testing structured feedback manage karti hai; Production global release rollout karti hai.
