Installation

Install analytics and @analytics/google-tag-manager packages

npm install analytics
npm install @analytics/google-tag-manager

How to use

The @analytics/google-tag-manager package works in the browser. 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'

const analytics = Analytics({
  app: 'awesome-app',
  plugins: [
    googleTagManager({
      containerId: 'GTM-123xyz'
    })
  ]
})

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

/* Track a custom event */
analytics.track('cartCheckout', {
  item: 'pink socks',
  price: 20
})

After initializing analytics with the googleTagManager plugin, data will be sent into Google Tag Manager whenever analytics.page, or analytics.track are called.

See additional implementation examples for more details on using in your project.

Configuring GTM

Make sure you have your google tags manager setup to fire on Page views.

Please see this example on wiring up "virtual page views" in google tag manager.

If you are using a SPA you want to listen to history changes as well.

See the full list of analytics provider plugins in the main repo.

Using multiple instances of GTM

As noted in the GTM docs, it's possible to load multiple instances of google tag manager on the page. This method is not exactly recommended by analytics experts if you can avoid it by using a single container. But if you must! You can!

import Analytics from 'analytics'
import googleTagManager from '@analytics/google-tag-manager'

const GTMOne = googleTagManager({ containerId: 'GTM-123xyz' })
// For instance 2, override the plugin 'name' and provide the 2nd GTM container ID
const GTMTwo = Object.assign({}, googleTagManager({ containerId: 'GTM-456abc'}), {
  name: 'google-tag-manager-two'
})

// Load up analytics
const analytics = Analytics({
  app: 'awesome-app',
  plugins: [
    GTMOne,
    GTMTwo
  ]
})

// Both instances will be loaded into the page

This functionality has been added by the wonderful @zobzn!

Custom name for dataLayer-object

The dataLayer is by default set to window.dataLayer. This can be changed by setting dataLayerName in plugin configuration.

import Analytics from 'analytics'
import googleTagManager from '@analytics/google-tag-manager'

const analytics = Analytics({
  app: 'awesome-app',
  plugins: [
    googleTagManager({
      containerId: 'GTM-123xyz',
      dataLayerName: 'customDataLayer',
    })
  ]
})
// dataLayer is initialized to window.customDataLayer

Tracking if JS is disabled

The analytics library will load the Google Tag manager javascript onto the page. This will work for every web site visitor that has javascript enabled.

For the small number of people who might have javascript disabled you will want to add the following <noscript> tags to the HTML of your site as outlined in GTM install docs

Add the following HTML to your site & replace GTM-XXXX with your container ID.

<!-- Google Tag Manager (noscript) -->
<noscript><iframe src="https://www.googletagmanager.com/ns.html?id=GTM-XXXX"
height="0" width="0" style="display:none;visibility:hidden"></iframe></noscript>
<!-- End Google Tag Manager (noscript) -->

If you are using multiple containers, you will want to add one <noscript> tag for each.

These days, apps typically don't even work without JS enabled & users must turn in on to use a site. So it's up to you & your use case if you want to add the additional <noscript> tags.
