Usage

Below is an example that utilizes this library along with enhanced ecommerce functionality and react-native-ab for A/B testing.

import React from 'react-native';
const {
  StyleSheet,
  Text,
  View,
  TouchableHighlight
} = React;
import { Experiment, Variant } from 'react-native-ab';
import {
  Analytics,
  Hits as GAHits,
  Experiment as GAExperiment
} from 'react-native-google-analytics';
import DeviceInfo from 'react-native-device-info';

let ga = this.ga = null;

export default class App extends React.Component {
  state = {
    experiments: {},
  }

  componentWillMount() {
    let clientId = DeviceInfo.getUniqueID();
    ga = new Analytics('UA-XXXXXXXX-X', clientId, 1, DeviceInfo.getUserAgent(), extra = {});
    let screenView = new GAHits.ScreenView(
      'Example App',
      'Welcome Screen',
      DeviceInfo.getReadableVersion(),
      DeviceInfo.getBundleId()
    );
    ga.send(screenView);
  }

  render() {
    return (
      <View style={styles.container}>
        <TouchableHighlight onPress={this._resetExperiment}>
          <View>
            <Experiment
              ref="welcomeMessageTest"
              name="welcome-message"
              onChoice={this._onChoice}>
              <Variant name="standard">
                <Text style={styles.welcome}>
                  Welcome to React Native!
                </Text>
              </Variant>
              <Variant name="friendly">
                <Text style={styles.welcome}>
                  Hey there! Welcome to React Native!
                </Text>
              </Variant>
              <Variant name="western">
                <Text style={styles.welcome}>
                  Howdy, partner! This here is React Native!
                </Text>
              </Variant>
            </Experiment>
          </View>
        </TouchableHighlight>
        <TouchableHighlight onPress={this._addImpression}>
          <Text style={styles.addImpressionTest}>
            Add GA Impression
          </Text>
        </TouchableHighlight>
        <TouchableHighlight onPress={this._sendEvent}>
          <Text style={styles.sendEventTest}>
            Send GA Event
          </Text>
        </TouchableHighlight>
        <Text style={styles.instructions}>
          To get started, edit index.ios.js
        </Text>
        <Text style={styles.instructions}>
          Press Cmd+R to reload,{'\n'}
          Cmd+Control+Z for dev menu
        </Text>
      </View>
    );
  }

  _onChoice = (testName, variantName) => {
    let experiment = new GAExperiment(testName, variantName);

    let state = {...this.state};
    state.experiments[testName] = experiment;
    this.setState(state);
  }

  _resetExperiment = () => {
    this.refs.welcomeMessageTest.reset();
  }

  _sendEvent = () => {
    let experiment = this.state.experiments['welcome-message'];
    let gaEvent = new GAHits.Event(
      'Demos',
      'send',
      'React Native',
      100,
      experiment
    );
    ga.send(gaEvent);
  }

  _addImpression = () => {
    var gaImpression = new GAHits.Impression(
      "P12345",
      "Product Name",
      "Product List",
      "Product Brand",
      "Product Category",
      "Product Variant",
      0, // Position
      200 // Price
    );
    ga.add(gaImpression);
  }
}

const styles = StyleSheet.create({
  container: {
    flex: 1,
    justifyContent: 'center',
    alignItems: 'center',
    backgroundColor: '#F5FCFF',
  },
  welcome: {
    fontSize: 20,
    textAlign: 'center',
    margin: 10,
  },
  instructions: {
    textAlign: 'center',
    color: '#333333',
    marginBottom: 5,
  },
  sendEventTest: {
    color: 'blue',
    fontSize: 16,
    textAlign: 'center'
  },
  addImpressionTest: {
    color: 'green',
    fontSize: 16,
    textAlign: 'center'
  }
});

Example of how to use custom dimensions:

  // Add a custom dimension with a given index & name
  ga.addDimension(1, 'male'); // This will add &cd1=male to all hits
  ga.addDimension(2, 'female');
  // To remove a custom dimension
  ga.removeDimension(1);
