Infermedica Modular Analytics

This package provides a common interface for sending data to web analytics tools like Google Analytics or Amplitude. Only basic functionality of tracking page views and events is currently supported.

Installation

$ npm install --save-dev @infermedica/modular-analytics

Configuration

The analytics interfaces has to be configured in Webpack configuration file through webpack.DefinePlugin:

new webpack.DefinePlugin({
  __analytics: JSON.stringify({
    debug: {
      isEnabled: true
    },
    googleAnalytics: {
      isEnabled: true,
      key: '<your-key>'
    },
    googleAdWords: {
      isEnabled: true,
      key: '<your-key>'
    },
    googleTagManager: {
      isEnabled: true
    },
    amplitude: {
      isEnabled: true,
      key: '<your-key>',
      allowProprties: [], // optional
      disallowProperties: ['application', 'user', 'section', 'event_details'], // optional
    },
    infermedicaAnalytics: {
      isEnabled: true,
      topic: '<your-topic>',
      environment: process.env.NODE_ENV,
      firebaseConfig: {
        apiKey: '<your-firebase-api-key>',
        authDomain: '<your-firebase-auth-domain>',
        appId: '<your-firebase-app-id>',
      },
      allowProperties: ['application', 'user', 'section', 'event_details'], // optional
      disallowProperties: [], // optional
    },
  })
})

You can use the above configuration to enable or disable individual modules. Use isEnabled to specify if particular module should be included in a final build.

Please note that isEnabled must be a boolean value (but you can still compute it from other variables), so Webpack's tree shaking algorithm can correctly detect and remove unused modules.

Usage

To use the module, you need to import the Analytics object and call its methods.

import {Analytics} from '@infermedica/modular-analytics';

Page view tracking

To track page views, use:

Analytics.trackView();

or:

Analytics.trackView('View Name');

Event tracking

To track events, use:

Analytics.trackEvent('Event name');

You can also pass additional properties, e.g.:

Analytics.trackEvent('Event name', {
  user_rating: 5
});

You can use the event for all modules or decide with modules should be used for this event, e.g.:

Analytics.trackEvent('Event name', {
  user_rating: 5
}, ['aplitude', 'googleTagManager'])

You can disable event for all modules, e.g.:

Analytics.trackEvent('Event name', {
  user_rating: 5
}, ['aplitude', 'googleTagManager'], true)

Conversion tracking

To track events, use:

Analytics.trackConversion('conversion-label');

The "conversion-label" will be passed to gtag function as follow:

window.gtag('event', 'conversion', {send_to: __analytics.googleAdWords.key + '/' + conversionLabel});

Setting global properties

You can set global properties that will be automatically added to each tracked event:

Analytics.setGlobalProperties('instance', 'my-page.example.com');

Multiple properties can be set at once, e.g.:

Analytics.setGlobalProperties({
  instance: 'my-page.example.com',
  interface_language: 'en',
});

Note that global properties can be overridden by parameters passed to trackEvent calls.

Usage with Vue.js

This package can be used as a Vue.js plugin:

import {VueAnalytics} from '@infermedica/modular-analytics';

Vue.use(VueAnalytics);

You can access it anywhere via Vue.$analytics:

Vue.$analytics.setGlobalProperties(...);
Vue.$analytics.trackView(...);
Vue.$analytics.trackEvent(...);

or with this.$analytics inside of Vue.js components:

this.$analytics.setGlobalProperties(...);
this.$analytics.trackView(...);
this.$analytics.trackEvent(...);

Supported analytics tools

Currently the following providers are supported:

• Google Analytics
• Google Tag Manager (Analytics & AdWords)
• Amplitude
• Infermedica Analytic

Other analytics tools are easy to integrate with this module and we might add their support in the future.
