analytics-plugin-defer v1.0.0

Defer plugin for analytics

Facilitates defering other analytics plugins and their associated events tracked with analytics. For example delay loading google-tag-manager in order to increase PageSpeed and once the deferred plugin is loaded then relay the events that occured prior to it loading to the now loaded plugin.

Installation

npm install analytics analytics-plugin-defer

How to use

To use, install the package, include in your project and initialize the plugin with analytics.

Below is an example of how to use the browser plugin.

import Analytics from 'analytics';
import googleTagManager from '@analytics/google-tag-manager';
import deferPlugin from 'analytics-plugin-defer';

const analytics = Analytics({
  app: 'example',
  plugins: [
    deferPlugin({ plugins: ['google-tag-manager'] }),
    googleTagManager({
      containerId: 'GTM-123456',
      enabled: false,
    }),
  ],
});

/* Track a page view */
analytics.page();

/* Track a custom event */
analytics.track('customEvent', {
  signup: true,
});

/* Identify a visitor */
analytics.identify('user', {
  firstName: 'Foo',
  lastName: 'Bar',
});

/* Deferred plugin will only load and be sent above events once the user iteracts with the page */

After initializing analytics with the analyticsDefer plugin, tracking data will be stored temporarily whenever analytics.page, analytics.track, or analytics.identify are called and will only be sent after there is interaction with the page upon which the deferred plugin is then loaded and the events are replayed.
