Install

• Add @forked-prs/nuxt-facebook-pixel-module dependency to your project

yarn add --dev @forked-prs/nuxt-facebook-pixel-module # or npm install --save-dev @forked-prs/nuxt-facebook-pixel-module

Getting Started

• Add @forked-prs/nuxt-facebook-pixel-module to the buildModules section of nuxt.config.js

export default {
  buildModules: [
    ['@forked-prs/nuxt-facebook-pixel-module', {
      track: 'PageView',
      pixelId: 'FACEBOOK_PIXEL_ID',
      disabled: false,
      debug: false,
    }]
  ]
}

:warning: If you are using Nuxt < v2.9 you have to install the module as a dependency (No --dev or --save-dev flags) and use modules section in nuxt.config.js instead of buildModules.

Using top level options

export default {
  buildModules: [
    '@forked-prs/nuxt-facebook-pixel-module'
  ],
  facebook: {
    track: 'PageView',
    pixelId: 'FACEBOOK_PIXEL_ID',
  }
}

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 {
  buildModules: [
    '@forked-prs/nuxt-facebook-pixel-module'
  ],

  facebook: {
    pixelId: '123456789012345', // Used as fallback if no runtime config is provided
  },

  publicRuntimeConfig: {
    facebook: {
      /* module options */
      pixelId: process.env.FB_PIXEL_ID || 'some-staging-key',
      disabled: false,
      debug: !!process.env.FB_PIXEL_DEBUG,
    }
  },
}

Disabling the pixel (for GDPR)

If you'd like to install the pixel disabled, and enable it later after the user has consented to its use, you can do so by setting disabled: true in the pixel configuration:

{
  buildModules: [
    '@forked-prs/nuxt-facebook-pixel-module',
  ],
  facebook: {
    ...
    disabled: true
  },
}

By Default it is disabled in development mode you can set debug: true

to enable while in dev or if using conjuction with runtimeconfig you can set FB_PIXEL_DEBUG=true in your .env

Now, in your component, you can call the following in order to start the pixel and track the current page.

this.$fb.enable()

Module options

List of possible options in the module:

Option	Default	Required	Description
pixelId	null	true	The unique pixel identifier provided by Facebook.
track	PageView	false	Default tracking event.
version	2.0	false	Tracking version.
disabled	false	false	Disable the Pixel by default when initialized. Can be enabled later through $fb.enable().

Facebook pixel instance

The tracking pixel instance is available on all vue component instances as $fb. It has the following methods:

Method	Purpose	Equivalent to
enable()	If you had previously set disabled: true in config, enables the pixel and tracks the current page view	$fb.init(), $fb.track()
init()	Initialises the pixel	fbq('init', <options.pixelId>)
track(event, parameters)	Sends a track event with optional parameters. It's PageView by default if the event is not defined.	fbq('track', <options.track>, parameters)
query(key, value, parameters)	Call the underlying fbq instance with anything else. The parameters attribute is optional.	fbq(key, value, parameters)
