GoogleAnalyticsBridge npm version Build Status

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');

Content

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);
  });

JavaScript API

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')

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.

GoogleAnalyticsSettings.setDispatchInterval(30);

setOptOut(enabled)
