README

Origami Tracking component

This module should be included on your product to make sending tracking requests to the Spoor API easy.

ScreenShot

Usage

Requirement: Polyfills & Doesn't cut the mustard

Applies to both quickstart examples below

Add the polyfill service to your site to make sure o-tracking runs in as many browsers as possible.

Require the noscript version of o-tracking incase the browser doesn't cut the mustard.

Checkout the Origami spec for the correct CTM logic, html and css changes needed.

o-tracking should have the following piece of html added, with the correct server and data filled in.

<div class="o-tracking o--if-no-js" data-o-component="o-tracking">
    <div style="background:url('http://server?data={}');"></div>
</div>

Recommended implementation using the build service

Use an onload handler to check when o-tracking has loaded and then init.

// CTM
if (cutsTheMustard) {
    var o = document.createElement('script');
    o.async = o.defer = true;
    o.src = 'https://build.origami.ft.com/v2/bundles/js?modules=o-tracking';
    var s = document.getElementsByTagName('script')[0];
    if (o.hasOwnProperty('onreadystatechange')) {
        o.onreadystatechange = function() {
            if (o.readyState === "loaded") {
                oTrackinginit();
            }
        };
    } else {
        o.onload = oTrackinginit;
    }
    s.parentNode.insertBefore(o, s);
}

The oTrackinginit function, used above, would have function calls to setup o-tracking and likely send a page view event. e.g.

function oTrackinginit() {
    var oTracking = Origami['o-tracking'];
    // Setup
    oTracking.init({...config...});
    // Page
    oTracking.page({...config...});
}

Alternative implementation using require

Use the build service or require locally to load o-tracking and init manually.

var oTracking = require('o-tracking');
if (cutsTheMustard) {
    // Setup
    oTracking.init({...config...});
    // Page
    oTracking.page({...config...});
}

Example implementations

Full example

<!DOCTYPE html>
<!-- Add core class to head tag -->
<head class="core">
<head>
    <title>Full example</title>
    <!-- Add CTM styles -->
    <style type="text/css">
        /* Hide any enhanced experience content when in core mode, and vice versa. */
        .core .o--if-js,
        .enhanced .o--if-no-js { display: none !important; }
    </style>
    <!-- Add CTM check -->
    <script>
        var cutsTheMustard = ('querySelector' in document && 'localStorage' in window && 'addEventListener' in window);
        if (cutsTheMustard) {
        // Swap the 'core' class on the HTML element for an 'enhanced' one
        // We're doing it early in the head to avoid a flash of unstyled content
        document.documentElement.className = document.documentElement.className.replace(/\bcore\b/g, 'enhanced');
        }
    </script>
    <!-- Add Polyfil service -->

<!-- Send an event -->
<button onclick="document.body.dispatchEvent(new CustomEvent('oTracking.event', { detail: { category: 'element', action: 'click' }, bubbles: true}));">Send an event</button>

</html>

Events

o-tracking will listen for 2 events as well as the funcations available above.

  • oTracking.page

    Send a page view event

    document.body.dispatchEvent(new CustomEvent('oTracking.page', { detail: { content: { uuid: 'abc-123', barrier: 'PREMIUM' }}, bubbles: true}));
    
  • oTracking.event

    Send a normal event

    document.body.dispatchEvent(new CustomEvent('oTracking.event', { detail: { category: 'video', action: 'play', id: '512346789', pos: '10' }, bubbles: true}));
    

Parameters

o-tracking will

  • Automatically pickup ftsession from cookies for you.
  • Page events automatically pick up the url and the referrer.

Events are decorated with config values you pass in via init() or updateConfig() if they are part of context, user, or device objects. Values passed in as context to individual events will override context values from init.

Init

{
    server: "...",
    context: {
        product: "..."
    },
    user: {
        ft_session: "..."
    },
    device: {
        orientation: "..."
    }
}

Updating core configuration

{
    device: {
        orientation: "..."
    }
}

Page

{
    url: "...",
    referrer: "..."
    content: {
        uuid: "...",
        hurdle: "..."
    }
    ... any other key-values ...
}

Event

Important: To decide how to name the category and action fields, consider this sentence (square brackets denote that part is optional):

A user can {action} a {category}[ with/having a {context}[ to {destination}]]

For example:

  • A user can view a page having a uuid.
  • A user can play a video having a video ID.
  • A user can share a comment having a comment ID to Facebook.
  • A user can share an article having a uuid to email.
  • A user can scroll a page with a asset type.
  • A user can open an email.
  • A user can click an element.
{
    category: 'video',
    action: 'play',
    ... any other key-values ...
    id: '512346789',
    pos: '10'
}
