• 🙆 Easy opt-out procedure for end-users;
• 🐞 Global Runtime Errors tracking - Whenever an error happens during runtime you will be reported to "Errors" section. This is super-useful as you never can test your client's code in all imaginable environments, but your website visitors do.

Analytics includes:

• Real-time users;
• Sessions;
• Unique users;
• Pageviews:
  • Page title;
  • Page URL.
• Demographics:
  • Country;
  • City.
• System:
  • Mobile devices;
  • Browsers;
  • Operating System.
• Behavior:
  • Custom events (see below);
  • Referrers.
• Global Scripts Errors and Exceptions:
  • Catch all JS-runtime errors and exceptions;
  • Browser name and release;
  • Operating System name and release;
  • Device name and version;
  • Script name and line number where the error occurred.

Installation

Installation options:

• Include suggested script tag into head of your HTML page - The simplest way;
• Include code from this repository into main website' script file;
• Install via NPM;
• Install via Atmosphere (Meteor).

To find installation instruction - go to Analytics section and select domain name for which you would like to install visitors metrics. To find "Tracking ID" click on "Show integration guide" and pick {{trackingId}} (17 symbols).

Script tag:

<script async defer type="text/javascript" src="https://analytics.ostr.io/{{trackingId}}.js"></script>

Meteor:

meteor add ostrio:analytics

Meteor via NPM:

meteor npm install ostrio-analytics --save

NPM:

npm install ostrio-analytics --save

Usage

Constructor new Analytics(trackingId [, auto])

• trackingId {String} - [Required] Website' identifier. To obtain trackingId see "Installation" section above;
• auto - {Boolean} - [Optional] Default - true. If set to false all visits and actions have to be tracked with .track() method, see below.

Script Tag:

// After including script-tag
// analytics automatically executes in 'auto' mode,
// its instance is available in global scope as `OstrioTracker`
// Example: OstrioTracker.pushEvent(foo, bar);

Meteor:

import Analytics from 'meteor/ostrio:analytics';
const analyticsTracker = new Analytics('trackingId');

Meteor via NPM:

const analyticsTracker = new (require('ostrio-analytics'))('trackingId');

NPM (CommonJS/RequireJS/Module):

const analyticsTracker = new (require('ostrio-analytics'))('trackingId');

Using minifed version:

// After adding minified analytics code to your project
// In global scope as `OstrioTrackerClass` and `OTC`
// as a short (short name was used in initial release,
// we keep it for compatibility reasons)

// Example:
const analyticsTracker = new OstrioTrackerClass('trackingId');
// Example 2:
const analyticsTracker = new window.OstrioTrackerClass('trackingId');
// Example 3:
const analyticsTracker = new OTC('trackingId');
// Example 4:
const analyticsTracker = new window.OTC('trackingId');
// Example 5: Initiate class with disabled "auto" tracking
// With disabled "auto" tracking you need to use
// `.track()` method to track a "visit"
const analyticsTracker = new window.OTC('trackingId', false);
whenUserVisit(() => {
  analyticsTracker.track();
});

From this point, you're good to go. All visitor's actions will be collected by ostr.io analytics. For custom events - see below.

.pushEvent(key, value) method

Custom events are useful for tracking certain activity on your website, like clicks, form submits and others user's behaviors.

• key {String} - [Required] The length of the event key must be between 1 and 24 symbols;
• value {String} - [Required] The length of the event value must be between 1 and 64 symbols.

If the length of key or value is longer than limits, it will be truncated without throwing an exception.

Examples:

// Various examples on tracking custom user's actions
analyticsTracker.pushEvent('userAction', 'login');
analyticsTracker.pushEvent('userAction', 'logout');
analyticsTracker.pushEvent('userAction', 'signup');

analyticsTracker.pushEvent('click', 'purchase');
analyticsTracker.pushEvent('click', 'purchase-left');
analyticsTracker.pushEvent('click', 'pricing - more info');

<script type="text/javascript">
  // make analyticsTracker global variable
  window.analyticsTracker = analyticsTracker;
</script>

<form>
  <h2>Buy Now</h2>
  <select>
    <option disabled>Select product</option>
    <option>Blue</option>
    <option>Red</option>
    <option>Green</option>
  </select>
  <input name="qty" />
  <!-- Example on tracking form submit -->
  <button type="submit" onClick="analyticsTracker.pushEvent('checkout', 'buy-now-form')">Checkout</button>
</form>

In a similar way using .pushEvent you can detect and track AdBlock usage and Accelerated Mobile Pages (AMP).

.track() method

Use to manually send tracking info. This method has no arguments.

Examples:

const Analytics = require('ostrio-analytics');
const analyticsTracker = new Analytics('trackingId', false);

// jQuery or any other similar case:
$(document).ready(() => {
  analyticsTracker.track();
});

.onPushEvent() method

Use to hook on .pushEvent() method. Read how to use this method for deep Google Analytics integration.

Examples:

const Analytics = require('ostrio-analytics');
const analyticsTracker = new Analytics('trackingId');

analyticsTracker.onPushEvent((key, value) => {
  console.log({ key, value });
  // OUTPUT:
  // { key: 'testKey', value: 'testValue' }
});

analyticsTracker.pushEvent('testKey', 'testValue');

.onTrack() method

Use to hook on .track() method and browser navigation. Read how to use this method for deep Google Analytics integration.

Examples:

const Analytics = require('ostrio-analytics');
const analyticsTracker = new Analytics('trackingId');

analyticsTracker.onTrack(() => {
  console.log('Tacking a session');
  // OUTPUT :
  // Tacking a session
});

// Callback will be executed on every browser navigation
// or upon calling `.track()` method
analyticsTracker.track();

Other examples

Deep router integration:

const Analytics = require('ostrio-analytics');
const analyticsTracker = new Analytics('trackingId', false);

/*!pseudo code!*/
router({
  '/'() {
    analyticsTracker.track();
  },
  '/two'() {
    analyticsTracker.track();
  },
  '/three'() {
    analyticsTracker.track();
  }
});

Deep History.js Integration

Although "History.js" and "History API" supported out-of-box, you may want to optimize tracking behavior to meet your needs.

const Analytics = require('ostrio-analytics');
const analyticsTracker = new Analytics('trackingId', false);

History.Adapter.bind(window, 'statechange', () => {
  analyticsTracker.track();
});

Google Analytics integration

Using .onTrack() method and .onPushEvent() method we can send tracking-data to Google Analytics upon navigation or event.

In your <head> add Google Analytics as instructed:

<script async src="https://www.googletagmanager.com/gtag/js?id=google-tracking-id"></script>
<script type='text/javascript'>
  window.dataLayer = window.dataLayer || [];
  function gtag(){dataLayer.push(arguments);}
  gtag('js', new Date());
</script>

const Analytics = require('ostrio-analytics');
const analyticsTracker = new Analytics('google-tracking-id');

analyticsTracker.onTrack(() => {
  // Track navigation with Google Analytics
  gtag('config', 'google-tracking-id', {
    page_title: document.title,
    page_path: document.location.pathname,
    page_location: document.location.href
  });
});

analyticsTracker.onPushEvent((name, value) => {
  // Send events to Google Analytics
  gtag('event', name, { value });
});

Opt-out for end-users

As our analytics solution fully respects DNT signals, to opt-out end-users need to activate DNT signals in a browser. To find out how to enable DNT and read more about "Do Not Track", visit - All About DNT homepage.
