vue-heatmapjs

A vue directive for collecting and displaying user activity on a component

Demo

Install

You can use NPM or Yarn to add this plugin to your project

npm install vue-heatmapjs
# or
yarn add vue-heatmapjs

Usage

You need to install this plugin in you main.js

// main.js

import Vue from 'vue'
import heatmap from 'vue-heatmapjs'

Vue.use(heatmap)

And then you can add the v-heatmap directive to the dom elements you want to track.

<!-- App.vue -->
<div v-heatmap>
  ...
</div>

Toggle heatmap

You can toggle the heatmap on and off by passing an expression into the directive, the example below will produce something similar to the image at the top of these docs

<template>
  ...
  <div v-heatmap="show"></div>
  <button @click="show = !show">Toggle Heatmap</button>
  ...
</template>

<script>
  ...
    data() {
      return {
        show: false,
      }
    },
  ...
</script>

Listen for events

Streams

You can pass in an Observable into the plugin options and subscribe to events captured for the heatmap.

// main.js
import { Subject } from 'rxjs';

const stream = new Subject();
Vue.use(Vueheatmap, {
  stream,
});

stream.subscribe(console.log);

Callback

You can pass an afterAdd method through with the plugin options, this will allow you to access and process the events captured for the heatmap

// main.js

Vue.use(heatmap, {
  afterAdd(data) {
    console.log(data)
    // you can fire this back to your analytics server
  },
})

Preload heatmap

Once you have captured heatmap data and persisted the data somewhere you will probably need a way of loading this data back in to your heatmap.

You can pass in an array of heatmap events using the heatmap preload plugin option

//main.js
Vue.use(Vueheatmap, {
  heatmapPreload: [{ x: 10, y: 10, value: 100 }],
});

The plugin can also handle a Promise

//main.js
Vue.use(Vueheatmap, {
  heatmapPreload: fetch('http://api.example.com').then(response => response.json()),
});
