GoogleAnalyticsBridge

Google Analytics Bridge is built to provide an easy interface to the native Google Analytics libraries on both iOS and Android.

Why a native bridge? Why not use just JavaScript?

The key difference with the native bridge is that you get a lot of the metadata handled automatically by the Google Analytics native library. This will include the device UUID, device model, viewport size, OS version etc.

You will only have to send in a few parameteres when tracking, e.g:

import { GoogleAnalyticsTracker } from "react-native-google-analytics-bridge";
let tracker = new GoogleAnalyticsTracker("UA-12345-1");

tracker.trackScreenView("Home");
tracker.trackEvent("testcategory", "testaction");

Use environment's Google Service Version (due to crash on Google Service version 12

You can specify googlePlayServicesVersion in "android/gradle.properties". Otherwise, it will take default version

e.g. googlePlayServicesVersion=11.8.0

Problems with tracking? Visitors not showing up?

This is NOT (normally) an error with this library. Please read this guide on how to set up your Google Analytics account/property for mobile analytics.

Installation and linking libraries

• For React Native >= 0.40 use version 5.0.0 (and up) of this module.
• For React Native < 0.40 use version 4.0.3.

Install with npm: npm install --save react-native-google-analytics-bridge

Or, install with yarn: yarn add react-native-google-analytics-bridge

Either way, then link with: react-native link react-native-google-analytics-bridge

If it doesn't work immediately after this, consult the manual installation guide. Both Android and iOS has a couple of prerequisite SDKs linked and installed.

Important: Does this library work with Expo? We have to sort of invert the question a bit, because it should be: does Expo work with other libraries? And the answer is no:

The most limiting thing about Expo is that you can’t add in your own native modules without detaching and using ExpoKit.

This includes using create-react-native-app which also makes use of Expo.

Usage

// You have access to three classes in this module:
import {
  GoogleAnalyticsTracker,
  GoogleTagManager,
  GoogleAnalyticsSettings
} from "react-native-google-analytics-bridge";

// The tracker must be constructed, and you can have multiple:
let tracker1 = new GoogleAnalyticsTracker("UA-12345-1");
let tracker2 = new GoogleAnalyticsTracker("UA-12345-2");

tracker1.trackScreenView("Home");
tracker1.trackEvent("Customer", "New");

// The GoogleAnalyticsSettings is static, and settings are applied across all trackers:
GoogleAnalyticsSettings.setDispatchInterval(30);
// Setting `dryRun` to `true` lets you test tracking without sending data to GA
GoogleAnalyticsSettings.setDryRun(true);

// GoogleTagManager is also static, and works only with one container. All functions here are Promises:
GoogleTagManager.openContainerWithId("GT-NZT48")
  .then(() => {
    return GoogleTagManager.stringForKey("pack");
  })
  .then(pack => {
    console.log("Pack: ", pack);
  })
  .catch(err => {
    console.log(err);
  });

Providing an existing GTM container

In some scenarios it might be helpful to provide an opened GTM container to the bridge. Some possible scenarios where this could be helpful:

• You want to preload some config before loading the jsbundle. For instance checking an experiment variable to determine which jsbundle to load.
• You have a brownfield app that mixes native UI and react native UI that should share the same container.
• You want to try and make sure that the container is loaded before starting the app.

This will require that you are familiar with the native api for GTM on whatever platforms you want to support. Generally the process is to load your container at startup, and hold the creation of the react native bridge until the container is loaded. On iOS you can then initialize an RCTGoogleTagManagerBridge and set the container property. On Android the process is similar, but you will need to supply the ContainerHolder to the GoogleAnalyticsBridgePackage instead.

JavaScript API

• GoogleAnalyticsTracker
• GoogleAnalyticsSettings
• GoogleTagManager

GoogleAnalyticsTracker API

new GoogleAnalyticsTracker(trackerId, customDimensionsFieldsIndexMap = {})

• trackerId (required): String, your tracker id, something like: UA-12345-1
• customDimensionsFieldsIndexMap (optional): {{fieldName: fieldIndex}} Custom dimensions field/index pairs

import { GoogleAnalyticsTracker } from "react-native-google-analytics-bridge";
let tracker = new GoogleAnalyticsTracker("UA-12345-1");

Google Analytics expects dimensions to be tracked by indices, and not field names. To simplify this, you can construct a tracker with a customDimensionsFieldsIndexMap. With this, you can map field names to indices, e.g:

let tracker2 = new GoogleAnalyticsTracker("UA-12345-3", { test: 1 });
tracker2.trackScreenViewWithCustomDimensionValues("Home", { test: "Beta" });

Here the underlying logic will transform the custom dimension, so what ends up being sent to GA is { 1: 'Beta' }. This should make it easier to use custom dimensions. If you do not provide a customDimensionsFieldsIndexMap, the custom dimensions are passed through untouched.

trackScreenView(screenName)

• screenName (required): String, name of current screen

Important: Calling this will also set the "current view" for other calls. So events tracked will be tagged as having occured on the current view, Home in this example. This means it is important to track navigation, especially if events can fire on different views.

See the Google Analytics docs for more info

tracker.trackScreenView("Home");

trackEvent(category, action, optionalValues)

• category (required): String, category of event
• action (required): String, name of action
• optionalValues: Object
  • label: String
  • value: Number

See the Google Analytics docs for more info.

tracker.trackEvent("testcategory", "testaction");
// or
tracker.trackEvent("testcategory", "testaction", {
  label: "v1.0.3",
  value: 22
});

trackTiming(category, value, optionalValues)

• category (required): String, category of the timed event
• value (required): Number, the timing measurement in milliseconds
• optionalValues: Object
  • name (required): String, the name of the timed event
  • label: String, the label of the timed event

See the Google Analytics docs for more info.

tracker.trackTiming("testcategory", 13000, { name: "LoadList" }); // name option is required
// or
tracker.trackTiming("testcategory", 13000, {
  name: "loadList",
  label: "v1.0.3"
});

Important: For iOS you can only use this method if you have done the optional step 6 from the installation guide. Only enable this (and link the appropriate libraries) if you plan to use advertising features in your app, or else your app may get rejected from the AppStore.

See the Google Analytics for more info.

GoogleAnalyticsSettings API

Settings are applied across all trackers.

setDryRun(enabled)

When enabled the native library prevents any data from being sent to Google Analytics. This allows you to test or debug the implementation, without your test data appearing in your Google Analytics reports.

GoogleAnalyticsSettings.setDryRun(true);

setDispatchInterval(intervalInSeconds)

• intervalInSeconds (required): Number, indicating how often dispatches should be sent

Events, screen views, etc, are sent in batches to your tracker. This function allows you to configure how often (in seconds) the batches are sent to your tracker. Recommended to keep this around 20-120 seconds to preserve battery and network traffic. This is set to 20 seconds by default.
