Vue Analytics

Simple implementation of Google Analytics in Vue.js

Standard - JavaScript Style Guide


This plugin will helps you in your common analytics tasks. Dispatching events, register some dimensions, metric and track views from Vue components.

Requirements

  • Vue.js. >= 2.0.0
  • Google Analytics account. To send data to

Optionnals dependencies

  • Vue Router >= 2.x - In order to use auto-tracking of screens

Configuration

npm install vue-ua -S
or
yarn add vue-ua
if you use Yarn package manager

Here is an example of configuration, compose with it on your own :

import VueAnalytics from 'vue-ua'
import VueRouter from 'vue-router'
const router = new VueRouter({routes, mode, linkActiveClass})

Vue.use(VueAnalytics, { appName: '', // Mandatory appVersion: '', // Mandatory trackingId: '', // Mandatory debug: true, // Whether or not display console logs debugs (optional) vueRouter: router, // Pass the router instance to automatically sync with router (optional) ignoredViews: ['homepage'], // If router, you can exclude some routes name (case insensitive) (optional) trackPage: true|false, // Whether you want page changes to be recorded as pageviews (website) or screenviews (app), default: false createOptions: { // Optional, Option when creating GA tracker, ref: https://developers.google.com/analytics/devguides/collection/analyticsjs/field-reference siteSpeedSampleRate: 10, }, globalDimensions: [ // Optional {dimension: 1, value: 'MyDimensionValue'}, {dimension: 2, value: 'AnotherDimensionValue'} ], globalMetrics: [ // Optional {metric: 1, value: 'MyMetricValue'}, {metric: 2, value: 'AnotherMetricValue'} ] })

Documentation

Once the configuration is completed, you can access vue analytics instance in your components like that :

export default {
    name: 'MyComponent',
    data () {
      return {
        someData: false
      }
    },
    methods: {
      onClick: function() {
        this.$ua.trackEvent('Banner', 'Click', 'I won money!')
        // OR
        this.$analytics.trackEvent('Banner', 'Click', 'I won money!')
      }
    },
    mounted () {
      this.$ua.trackView('MyScreenName')
    }
}

You can also access the instance anywhere whenever you imported

Vue
by using
Vue.analytics
. It is especially useful when you are in a store module or somewhere else than a component's scope.

Sync analytics with your router

Thanks to vue-router guards, you can automatically dispatch new screen views on router change ! To use this feature, you just need to inject the router instance on plugin initialization.

This feature will generate the view name according to a priority rule : - If you defined a meta field for you route named

analytics
this will take the value of this field for the view name. - Otherwise, if the plugin don't have a value for the
meta.analytics
it will fallback to the internal route name.

Most of time the second case is enough, but sometimes you want to have more control on what is sent, this is where the first rule shine.

Example :

javascript
const myRoute = {
  path: 'myRoute',
  name: 'MyRouteName',
  component: SomeComponent,
  meta: {analytics: 'MyCustomValue'}
}

This will use

MyCustomValue
as the view name.
