Usage

Bundler (Webpack, Rollup)

import Vue from 'vue'
import LZ_PIWIK from 'lz-piwik'

Vue.use(LZ_PIWIK, {
  // Configure your matomo server and site by providing
  host: 'https://matomo.example.com',
  siteId: 5,

  // Changes the default .js and .php endpoint's filename
  // Default: 'matomo'
  trackerFileName: 'matomo',

  // Overrides the autogenerated tracker endpoint entirely
  // Default: undefined
  // trackerUrl: 'https://example.com/whatever/endpoint/you/have',

  // Overrides the autogenerated tracker script path entirely
  // Default: undefined
  // trackerScriptUrl: 'https://example.com/whatever/script/path/you/have',

  // Enables automatically registering pageviews on the router
  router: router,

  // Enables link tracking on regular links. Note that this won't
  // work for routing links (ie. internal Vue router links)
  // Default: true
  enableLinkTracking: true,

  // Require consent before sending tracking information to matomo
  // Default: false
  requireConsent: false,

  // Whether to track the initial page view
  // Default: true
  trackInitialView: true,

  // Run Matomo without cookies
  // Default: false
  disableCookies: false,

  // Enable the heartbeat timer (https://developer.matomo.org/guides/tracking-javascript-guide#accurately-measure-the-time-spent-on-each-page)
  // Default: false
  enableHeartBeatTimer: false,

  // Set the heartbeat timer interval
  // Default: 15
  heartBeatTimerInterval: 15,

  // Whether or not to log debug information
  // Default: false
  debug: false,

  // UserID passed to Matomo (see https://developer.matomo.org/guides/tracking-javascript-guide#user-id)
  // Default: undefined
  userId: undefined,

  // Share the tracking cookie across subdomains (see https://developer.matomo.org/guides/tracking-javascript-guide#measuring-domains-andor-sub-domains)
  // Default: undefined, example '*.example.com'
  cookieDomain: undefined,

  // Tell Matomo the website domain so that clicks on these domains are not tracked as 'Outlinks'
  // Default: undefined, example: '*.example.com'
  domains: undefined,

  // A list of pre-initialization actions that run before matomo is loaded
  // Default: []
  // Example: [
  //   ['API_method_name', parameter_list],
  //   ['setCustomVariable','1','VisitorType','Member'],
  //   ['appendToTrackingUrl', 'new_visit=1'],
  //   etc.
  // ]
  preInitActions: []
});

// Now you can access piwik api in components through
this.$matomo

// or
window._paq.push

// or through
window.Piwik.getTracker

For available operations see the matomo api docs

Note on async loading

This plugin loads the matomo.js asynchronously, which means it is possible that $matomo is not (yet) loaded. Furthermore anti-tracking plugins on browsers might block matomo.js entirely. You should always guard your calls to $matomo, or use window._paq.push:

this.$matomo && this.$matomo.trackPageView()

// Or...

window._paq.push(['trackPageView'])

Note on external link tracking

When using the option to trackExternalLinks, lz-piwik ensures the corresponding Matomo method is called after each navigation event. Matomo scans the entire DOM for external links and adds its link handling. This means that if your external links are rendered dynamically these links may not be picked up. You need to call this method manually if links might not exist after the page has finished rendering (for example if the links come from some REST call). For more information refer to https://developer.matomo.org/guides/spa-tracking#link-tracking

this.$matomo && this.$matomo.enableLinkTracking()

// Or...

window._paq.push(['enableLinkTracking'])

Nuxt

Nuxt can work by creating a plugin that will load VueMatomo with SSR disabled. Note how the router is passed in the second snippet:

// nuxt.config.js

export default {
  plugins: [
    { src: '~/plugins/tydic-lz-piwik.js', ssr: false }
  ]
}

// plugins/lz-piwik.js

import Vue from 'vue'
import VueMatomo from 'lz-piwik'

export default ({ app }) => {
  Vue.use(VueMatomo, {
    router: app.router

    /** Other configuration options **/
  })
}

Ignoring routes

It is possible to ignore routes using the route meta:

{
  path: '/page-2',
  name: 'Page2',
  component: Page2,
  meta: {
    analyticsIgnore: true
  }
}

Managing consent

First of all load the plugin with the requireConsent option enabled:

Vue.use(VueMatomo, {
  // ...
  requireConsent: true
})

Matomo has a built in way to give and remember consent. The simplest way is to simply use this method provided by Matomo:

<button @click="handleConsent()">Accept Cookies</button>

handleConsent() {
  this.$matomo.rememberConsentGiven()
}

Another option is to use your own implementation for remembering consent. In that case you can simply call this.$matomo.setConsentGiven() on each page load when you establish that the user has given consent.

Build

Bundle the js and css of to the dist folder:

npm run build
