Vue Analytics

Simple implementation of Google Analytics in Vue.js

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: '<app_name>', // Mandatory
  appVersion: '<app_version>', // Mandatory
  trackingId: '<your_tracking_id>', // 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 :

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

This will use MyCustomValue as the view name.

trackView (screenName, trackPage = false)

 /**
   * Dispatch a view using the screen name
   * 
   * @param screenName {string}
   * @param trackPage {boolean} - Whether you want the dispatched view to be recorded as pageview (website) or screenview (app)
   */

trackTiming (timingCategory, timingVar, timingValue, timingLabel = null)

/**
   * Track an user timing to measure periods of time.
   *
   * @param {string} timingCategory - A string for categorizing all user timing variables into logical groups (e.g. 'JS Dependencies').
   * @param {string} timingVar -  A string to identify the variable being recorded (e.g. 'load').
   * @param {number} timingValue - The number of milliseconds in elapsed time to report to Google Analytics (e.g. 20).
   * @param {string|null} timingLabel -  A string that can be used to add flexibility in visualizing user timings in the reports (e.g. 'Google CDN').
