Google Analytics integration for use with React Native apps built on Expo. Most of the other Google Analytics libraries I've found require linking, which is not supported with Expo. This library does not require linking.
Please create issues for any bugs you find or features you would like added.
npm install expo-analytics --save
Your React Native app's screen resolution, app name, app ID, app version and multiple other parameters will be automatically resolved and sent with each hit or event.
Sending page hits or screen hits is done by constructing a new PageHit or ScreenHit instance and passing it to the hit function of an Analytics instance.
import { Analytics, PageHit } from 'expo-analytics';
const analyticsProxy = new Analytics('UA-XXXXXX-Y');
analyticsProxy.hit(new PageHit('Home'));
You can also optionally include any additional supported parameters you would like.
import { Analytics } from 'expo-analytics';
// pass in the user ID (uid), referrer (dr) and campaign name (cn)
const analyticsProxy = new Analytics('UA-XXXXXX-Y', { uid: '999', dr: 'github.com', cn: 'get_more_views' });
You can also send custom events by constructing a new Event instance and passing it to the event function. Events have four parameters.
- Event Category
- Event Action
- Event Label (optional, but recommended)
- Event Value (optional, integer)
These parameters are passed to the Event constructor in that order.
import { Analytics, Event } from 'expo-analytics';
const analyticsProxy = new Analytics('UA-XXXXXX-Y');
analyticsProxy.event(new Event('Video', 'Play', 'The Big Lebowski', 123));
Learn more about custom events.
The Google Analytics API is a bit particular. If you're not seeing Real Time hits in your Analytics console you can turn on debug mode for this package and the exact URL request being sent will be printed to the console.
import { Analytics, PageHit } from 'expo-analytics';
const analyticsProxy = new Analytics('UA-XXXXXX-Y', null, { debug: true });
analyticsProxy.hit(new PageHit('IsItWorking'));
