Usage Examples

Firebase Analytics Setup (iOS)

// AppDelegate.swift
import FirebaseCore
import FirebaseAnalytics

@main
class AppDelegate: UIResponder, UIApplicationDelegate {
    func application(_ application: UIApplication,
                     didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
        FirebaseApp.configure()
        return true
    }
}

// Analytics Helper
struct AnalyticsManager {
    static func logEvent(_ name: String, parameters: [String: Any]? = nil) {
        Analytics.logEvent(name, parameters: parameters)
    }

    static func setUserId(_ userId: String) {
        Analytics.setUserID(userId)
    }

    static func setUserProperty(_ value: String?, forName name: String) {
        Analytics.setUserProperty(value, forName: name)
    }

    static func logScreenView(screenName: String, screenClass: String) {
        Analytics.logEvent(AnalyticsEventScreenView, parameters: [
            AnalyticsParameterScreenName: screenName,
            AnalyticsParameterScreenClass: screenClass
        ])
    }
}

Firebase Analytics Setup (Android)

// AnalyticsManager.kt
class AnalyticsManager @Inject constructor(
    private val analytics: FirebaseAnalytics
) {
    fun logEvent(name: String, params: Map<String, Any>? = null) {
        analytics.logEvent(name, params?.toBundle())
    }

    fun setUserId(userId: String?) {
        analytics.setUserId(userId)
    }

    fun setUserProperty(name: String, value: String?) {
        analytics.setUserProperty(name, value)
    }

    fun logScreenView(screenName: String, screenClass: String) {
        analytics.logEvent(FirebaseAnalytics.Event.SCREEN_VIEW) {
            param(FirebaseAnalytics.Param.SCREEN_NAME, screenName)
            param(FirebaseAnalytics.Param.SCREEN_CLASS, screenClass)
        }
    }
}

private fun Map<String, Any>.toBundle(): Bundle {
    return Bundle().apply {
        this@toBundle.forEach { (key, value) ->
            when (value) {
                is String -> putString(key, value)
                is Int -> putInt(key, value)
                is Long -> putLong(key, value)
                is Double -> putDouble(key, value)
                is Boolean -> putBoolean(key, value)
            }
        }
    }
}

Event Schema

// analytics/events.ts
export const AnalyticsEvents = {
  // User Events
  USER_SIGNED_UP: 'user_signed_up',
  USER_LOGGED_IN: 'user_logged_in',
  USER_LOGGED_OUT: 'user_logged_out',

  // Feature Events
  FEATURE_USED: 'feature_used',
  ITEM_VIEWED: 'item_viewed',
  ITEM_ADDED_TO_CART: 'item_added_to_cart',
  PURCHASE_COMPLETED: 'purchase_completed',

  // Engagement Events
  SHARE_CLICKED: 'share_clicked',
  NOTIFICATION_RECEIVED: 'notification_received',
  NOTIFICATION_OPENED: 'notification_opened',
} as const;

export interface EventParameters {
  user_signed_up: { method: 'email' | 'google' | 'apple' };
  item_viewed: { item_id: string; item_name: string; category: string };
  purchase_completed: { transaction_id: string; value: number; currency: string };
}
