Getting Started

Add nnuxt3-meta-pixel to modules section of nuxt.config.js.

{
  modules: [
    'nuxt3-meta-pixel',
  ],
  facebook: {
    /* module options */
    track: 'PageView',
    pixelId: 'FACEBOOK_PIXEL_ID',
    autoPageView: true,
    disabled: false
  },
}

Automatically track PageView

By default, the module won't trigger any tracking event on route change. To enable this behaviour, you must specify the autoPageView option and set to true in the Nuxt module options.

{
  modules: [
    'nuxt3-meta-pixel',
  ],
  facebook: {
    /* module options */
    pixelId: 'FACEBOOK_PIXEL_ID',
    autoPageView: true
  },
}

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:

{
  modules: [
    'nuxt3-meta-pixel',
  ],
  facebook: {
    ...
    disabled: true
  },
}

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

this.$fb.enable()

The pixel can be disabled again later on by using the .disable() method.

Multiple pixel codes according to route

It's possible to use multiple pixel codes according to the user's route. This can be made through the pixels property. The pixels property expects an array of options.

{
  modules: [
    'nuxt3-meta-pixel',
  ],
  facebook: {
    pixelId: 'DEFAULT_PIXEL_ID',
  },
}

Per this example, whenever the user is on the /my-custom-route, it will use the FACEBOOK_PIXEL_ID instead of the DEFAULT_PIXEL_ID. For all the other routes, it will use the default one.

Note : Since the pixels property is an array of options, any other valid option (track, manualMode, ...) can be passed.

Advanced Matching

To send custom user data when initializing the FB Pixel you'll have to disable the plugin in your Nuxt config file and enable it once you've set the user data.

Run the following from your Vue component once you've access to the user data:

this.$fb.setUserData({ external_id: 32323, fn: 'John' })
this.$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() and disabled again with $fb.disable().
debug	false	false	By default, tracking in development mode is disabled. By specifying true, you manually allow tracking in development mode.
manualMode	false	false	By default, Facebook will trigger button click and page metadata. Set to true to disable this behaviour. See more informations
autoPageView	false	false	If set to true, automatically triggers a PageView track event on every page change.

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()
disable()	Disables the pixel again
setPixelId()	Change the default pixelId & trigger an init it
setUserData(userData)	Used to set user data that'll be used once the fbq init function is called. See Advanced Matching.
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)
