    ]
  }
}

Usage

Initialize Session

import ExpoIombLibrary from "expo-iomb-library";
import { Platform } from "react-native";

const isIos = Platform.OS === "ios";

const baseURL = isIos ? "<yourIosBaseURL>" : "<yourAndroidBaseURL>";

const offerIdentifier = isIos
  ? "<yourIosIdentifier>"
  : "<yourAndroidIdentifier>";

// Configure and start session
await ExpoIombLibrary.sessionConfiguration({
  baseURL,
  offerIdentifier,
});

Track View Events

import { IOMBViewEvent } from "expo-iomb-library";

await ExpoIombLibrary.logViewEvent({
  type: IOMBViewEvent.APPEARED,
  category: "your-category",
  comment: "your-optional-comment",
});

Set Debug Level

import { IOMBDebugLevel } from "expo-iomb-library";
import { Platform } from "react-native";

if (Platform.OS === "ios") {
  await ExpoIombLibrary.setDebugLogLevel(IOMBDebugLevel.TRACE);
} else {
  await ExpoIombLibrary.setDebugModeEnabled(true);
}

Cleanup

await ExpoIombLibrary.terminateSession();
