Project ID & API Keys

Login to Keen IO to create a project and grab the Project ID and Write Key from your project's Access page.

Getting started

The following examples demonstrate how to implement rock-solid web analytics, capturing pageviews, clicks, and form submissions with robust data models.

Not interested in web analytics? Use these examples as a primer for getting up and running quickly. These examples also make use of several helpers and utilities that were designed to address common requirements and help produce insightful, valuable data models.

Automated Event Tracking (Browser-only)

Automatically record pageviews, clicks, and form_submissions events with robust data models:

<script src="https://d26b395fwzu5fz.cloudfront.net/keen-tracking-2.0.1.min.js"></script>
<script>
Keen.ready(function(){
  var client = new Keen({
    projectId: 'YOUR_PROJECT_ID',
    writeKey: 'YOUR_WRITE_KEY'
  });
  client.initAutoTracking();
});
</script>

Pageview Tracking (Browser/Front-end)

First, let's create a new client instance with your Project ID and Write Key, and use the .extendEvents() method to define a solid baseline data model that will be applied to every single event that is recorded. Consistent data models and property names make life much easier later on, when analyzing and managing several event streams. This setup also includes our data enrichment add-ons, which will populate additional information when an event is received on our end.

import Keen from 'keen-tracking';

const client = new Keen({
  projectId: 'PROJECT_ID',
  writeKey: 'WRITE_KEY'
});
const helpers = Keen.helpers;
const utils = Keen.utils;

const sessionCookie = utils.cookie('rename-this-example-cookie');
if (!sessionCookie.get('guest_id')) {
  sessionCookie.set('guest_id', helpers.getUniqueId());
}

client.extendEvents(() => {
  return {
    geo: {
      info: { /* Enriched */ },
      ip_address: '${keen.ip}',
    },
    page: {
      info: { /* Enriched */ },
      title: document.title,
      url: document.location.href
    },
    referrer: {
      info: { /* Enriched */ },
      url: document.referrer
    },
    tech: {
      browser: helpers.getBrowserProfile(),
      info: { /* Enriched */ },
      user_agent: '${keen.user_agent}'
    },
    time: helpers.getDatetimeIndex(),
    visitor: {
      guest_id: sessionCookie.get('guest_id')
      /* Include additional visitor info here */
    },
    keen: {
      addons: [
        {
          name: 'keen:ip_to_geo',
          input: {
            ip: 'geo.ip_address'
          },
          output : 'geo.info'
        },
        {
          name: 'keen:ua_parser',
          input: {
            ua_string: 'tech.user_agent'
          },
          output: 'tech.info'
        },
        {
          name: 'keen:url_parser',
          input: {
            url: 'page.url'
          },
          output: 'page.info'
        },
        {
          name: 'keen:referrer_parser',
          input: {
            referrer_url: 'referrer.url',
            page_url: 'page.url'
          },
          output: 'referrer.info'
        }
      ]
    }
  }
});

client.recordEvent('pageviews', {});

Every event that is recorded will inherit this baseline data model. Additional properties defined in client.recordEvent() will be applied before the event is finally recorded.

Click and Form Submit Tracking (Browser/Front-end)

Clicks and form submissions can be captured with .listenTo(). This function intercepts events for designated elements and creates a brief 500ms delay, allowing an HTTP request to execute before the page begins to unload.

This example further extends the client instance defined previously, and activates a simple timer when the page the loaded. Once a click or submit event is captured, the timer's value will be recorded as visitor.time_on_page.

import Keen from 'keen-tracking';

const client = new Keen({
  projectId: 'PROJECT_ID',
  writeKey: 'WRITE_KEY'
});
const helpers = Keen.helpers;
const timer = Keen.utils.timer();
timer.start();

Keen.listenTo({
  'click .nav a': function(e){
    client.recordEvent('click', {
      action: {
        intent: 'navigate',
        target_path: helpers.getDomNodePath(e.target)
      },
      visitor: {
        time_on_page: timer.value()
      }
    });
  },
  'submit form#signup': function(e){
    client.recordEvent('form-submit', {
      action: {
        intent: 'signup',
        target_path: helpers.getDomNodePath(e.target)
      },
      visitor: {
        email_address: document.getElementById('signup-email').value,
        time_on_page: timer.value()
      }
    });
  }
});

Block Bots and Improve Device Recognition (Browser/Front-end)

Install mobile-detect.js to identify basic device types and block noisy bots and crawlers.

$ npm install mobile-detect --save

This example further extends the client instance defined above, inserting a new tech.device_type property with three possible values: 'desktop', 'mobile', and 'tablet'. If the user agent is determined to be a bot, it may be ideal to abort and avoid recording an event.

import MobileDetect from 'mobile-detect';

const md = new MobileDetect();
if (md.is('bot')) {
  return false;
}

// extends client instance defined previously
client.extendEvents(() => {
  return {
    tech: {
      device_type: md.tablet() ? 'tablet' : md.mobile() ? 'mobile' : 'desktop'
    }
  };
});

Check out the many additional methods supported by mobile-detect.js to further enrich your data model.

This can also be used with automated event tracking.

Server Side Tracking (Back-end)

const Keen = require('keen-tracking');

const client = new Keen({
  projectId: 'PROJECT_ID',
  writeKey: 'WRITE_KEY'
});

client.recordEvent('purchases', {
  item: 'Avocado',
  price: 12
});
