A Nuxt 3 module thats injects Meta Pixel (Facebook Pixel)
$ npm install --save nuxt3-meta-pixel
// or
$ yarn add nuxt3-meta-pixel
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
},
}
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
},
}
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
},
}
How to access $fb ?
import { useNuxtApp } from '#app';
const nuxtApp = useNuxtApp()
console.log(nuxtApp.$fb)
Now, in your component, you can call the following in order to start the pixel and track the current page.
nuxtApp.$fb.enable()
The pixel can be disabled again later on by using the .disable()
method.
It's possible to use multiple pixel codes according to the user's route. This can be made through the pixels
property.
The pixels
property expects an array of options.
{
modules: [
'nuxt3-meta-pixel',
],
facebook: {
pixelId: 'DEFAULT_PIXEL_ID',
},
}
Per this example, whenever the user is on the /my-custom-route
, it will use the FACEBOOK_PIXEL_ID
instead of the DEFAULT_PIXEL_ID
. For all the other routes, it will use the default one.
Note : Since the pixels
property is an array of options, any other valid option (track
, manualMode
, ...) can be passed.
To send custom user data when initializing the FB Pixel you'll have to disable the plugin in your Nuxt config file and enable it once you've set the user data.
Run the following from your Vue component once you've access to the user data:
nuxtApp.$fb.setUserData({ external_id: 32323, fn: 'John' })
nuxtApp.$fb.enable()

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. |
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', |
track(event, parameters) | Sends a track event with optional parameters . It's PageView by default if the event is not defined. |
fbq('track', |
query(key, value, parameters) | Call the underlying fbq instance with anything else. The parameters attribute is optional. |
fbq(key, value, parameters) |
