@nuxtjs/gtm

Google Tag Manager Module for Nuxt.js

This is a temporary fork so we can utilise the new Runtime Config options

ℹ️ If coming from v1 (@nuxtjs/google-tag-manager) please read v2 release notes.

Setup

Add @thomaswilliammcclean/nuxtgtm dependency to your project

yarn add @nuxtjs/gtm # or npm install @nuxtjs/gtm

Add @nuxtjs/gtm to the modules section of nuxt.config.js

export default {
  modules: [
    '@nuxtjs/gtm',
  ],
  gtm: {
    id: 'GTM-XXXXXXX'
  }
}

Runtime Config

You can use runtime config if need to use dynamic environment variables in production. Otherwise, the options will be hardcoded during the build and won't be read from nuxt.config anymore.

export default {
  modules: [
    '@nuxtjs/gtm'
  ],

  gtm: {
    id: 'GTM-XXXXXXX', // Used as fallback if no runtime config is provided
  },

  publicRuntimeConfig: {
    gtm: {
      id: process.env.GOOGLE_TAG_MANAGER_ID
    }
  },
}

Options

Defaults:

export default {
  gtm: {
    enabled: undefined, /* see below */
    debug: false,

    id: undefined,
    layer: 'dataLayer',
    variables: {},

    pageTracking: false,
    pageViewEventName: 'nuxtRoute',

    autoInit: true,
    respectDoNotTrack: true,

    scriptId: 'gtm-script',
    scriptDefer: false,
    scriptURL: 'https://www.googletagmanager.com/gtm.js',

    noscript: true,
    noscriptId: 'gtm-noscript',
    noscriptURL: 'https://www.googletagmanager.com/ns.html'
  }
}

`enabled`

GTM module uses a debug-only version of $gtm during development (nuxt dev).

You can explicitly enable or disable it using enabled option:

export default {
  gtm: {
    // Always send real GTM events (also when using `nuxt dev`)
    enabled: true
  }
}

`debug`

Whether $gtm API calls like init and push are logged to the console.

Manual GTM Initialization

There are several use cases that you may need more control over initialization:

Block Google Tag Manager before user directly allows (GDPR realisation or other)
Dynamic ID based on request path or domain
Initialize with multi containers
Enable GTM on page level

nuxt.config.js:

export default {
 modules: [
  '@nuxtjs/gtm'
 ],
 plugins: [
  '~/plugins/gtm'
 ]
}

plugins/gtm.js:

export default function({ $gtm, route }) {
  $gtm.init('GTM-XXXXXXX')
}

Note: All events will be still buffered in data layer but won't send until init() method getting called.
Note: Please consult with Google Tag Manager Docs for more information caveats using multiple containers.

Router Integration

You can optionally set pageTracking option to true to track page views.

Note: This is disabled by default to prevent double events when using alongside with Google Analytics so take care before enabling this option.

The default event name for page views is nuxtRoute, you can change it by setting the pageViewEventName option.

Usage

Pushing events

You can push events into the configured layer:

this.$gtm.push({ event: 'myEvent', ...someAttributes })

Development

Clone this repository
Install dependencies using yarn install or npm install
Start development server using yarn dev or GTM_ID=<your gtm id> yarn dev if you want to provide custom GTM_ID.
