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.
