Coveo Usage Analytic JavaScript client

This project provides 2 ways to interact with the Coveo Usage Analytics service.

• A JavaScript browser client
• A code snippet to add in website pages

Usage (Web analytics)

This JavaScript client provides a code snippet that can easily be added to website pages to track events. The pageview events are stored in a Coveo Usage Analytics table which content currently cannot be viewed in Usage Analytics reports and the visit browser to prevent performance degradation.

Initially, the pageview events data will be used exclusively by the Coveo ML Event Recommendations (ER) Feature (see Event Recommendations (ER) Feature). It is recommended that you start sending pageview events to the Coveo Usage Analytics service as soon as possible so that you get relevant items recommended.

On top of pageview events, generic and commerce events can also be tracked. See Tracking Commerce Events.

Note: This Coveo code snippet is similar to the Google analytics one (analytics.js).

Sending Coveo Analytics Page View Events for Recommendations

1. Get an API key.

   You need a Coveo Cloud API key which has the Push access level on the Analytics Data domain to send events (see User Authentication).

   Create an API key from the administration console selecting the Push option box for the Analytics Data domain (see Adding and Managing API Keys).

2. Add the code snippet to all your website pages.

   Add a code snippet like the following to all pages of your websites:

   <script>
       (function(c,o,v,e,O,u,a){
       a='coveoua';c[a]=c[a]||function(){(c[a].q=c[a].q|| []).push(arguments)};
       c[a].t=Date.now();u=o.createElement(v);u.async=1;u.src=e;
       O=o.getElementsByTagName(v)[0];O.parentNode.insertBefore(u,O)
       })(window,document,'script','https://static.cloud.coveo.com/coveo.analytics.js/2/coveoua.js')
       // Replace "2" in the script url with the latest release
   
       coveoua('init', <COVEO_API_KEY>); // Replace <COVEO_API_KEY> with your real key
       coveoua('send', 'view', {
           contentIdKey: '@permanentid',
           contentIdValue: <PERMANENT_ID_VALUE>, // Replace <PERMANENT_ID_VALUE> with a unique value from your page.
           contentType: 'product', // Optional
           // ... more information ...
       });
   </script>
   

   The code snippet must contain contentIdKey and contentIdValue in order to identify items in the Coveo index. When you want to recommend specific types of content, you also need to add a contentType parameter value.

   Key	Value
   contentIdKey	The Coveo index field name that will be used to identify the item.
   contentIdValue	The Coveo index field value that will be used to identify the item.
   contentType	[Optional] The type of the item to be tracked (e.g., 'Article').

   Note: Do not copy the coveoua.js file as it can be updated anytime and you could experience compatibility issues.

3. Validate pageview events are sent to the Coveo Usage Analytics service

   a. In a web browser such as Chrome, navigate to a website page to which you added the code snippet.

   b. In the browser developer tool, go the the Network tab.

   c. Reload the page, in the Name panel, ensure that you see a view event sent to Coveo analytics.

Sending Any Coveo Analytics Events

Add the code snippet to all your website pages.

<script>
    (function(c,o,v,e,O,u,a){
    a='coveoua';c[a]=c[a]||function(){(c[a].q=c[a].q|| []).push(arguments)};
    c[a].t=Date.now();u=o.createElement(v);u.async=1;u.src=e;
    O=o.getElementsByTagName(v)[0];O.parentNode.insertBefore(u,O)
    })(window,document,'script','https://static.cloud.coveo.com/coveo.analytics.js/2/coveoua.js') // Replace "2" in the script url with the latest release
    coveoua('init', <COVEO_API_KEY>); // Replace <COVEO_API_KEY> with your real key
</script>

You can now call the script using the following line:

coveoua('send', 'click', { ... });

Refer to the Usage Analytics Write API section to see what types of events are supported and what payload you need to send.

Sending Commerce Events

Add the code snippet to all your website pages.

<script>
    (function(c,o,v,e,O,u,a){
    a='coveoua';c[a]=c[a]||function(){(c[a].q=c[a].q|| []).push(arguments)};
    c[a].t=Date.now();u=o.createElement(v);u.async=1;u.src=e;
    O=o.getElementsByTagName(v)[0];O.parentNode.insertBefore(u,O)
    })(window,document,'script','https://static.cloud.coveo.com/coveo.analytics.js/2/coveoua.js') // Replace "2" in the script url with the latest release
    coveoua('init', <COVEO_API_KEY>); // Replace <COVEO_API_KEY> with your real key
</script>

To send commerce events, call coveoua with the event name. Here is how an addition to the cart interaction is measured:

1. First use the ec:addProduct command to include the relevant product data in the event you’re about to send

   coveoua('ec:addProduct', <PRODUCT_DATA>);
   

2. Then use the ec:setAction command to specify that the action done on this data is an addition to the cart:

   coveoua('ec:setAction', 'add');
   

3. Finally, use the send command to send the event to Coveo Usage Analytics.

   coveoua('send', 'event');
   

Refer to the Tracking Commerce Events page to see how to measure a product details view, an addition to the cart, a removal from the cart, a purchase or an event on a search-driven listing-page in more details.

All supported actions are also listed in the Possible Actions section of the Tracking Commerce Events page.

Usage (for developers)

You need to provide your own fetch API compatible libraries in the global environment (see Isomorphic TypeScript, fetch, promises, ava and coverage).

npm install coveo.analytics isomorphic-fetch

import fetch from 'isomorphic-fetch'; // isomorphic-fetch modifies the global environment
import coveoanalytics from 'coveo.analytics';

// Create an API client
const client = new coveoanalytics.analytics.Client({token: 'YOUR_API_KEY'});
// Send your event
client.sendCustomEvent({
    eventType: 'dog',
    eventValue: 'Hello! Yes! This is Dog!',
});

Choosing the type of storage for page view events

There are 3 available storage types you can use to store view events client side.

• Cookie storage, which supports top level domain storage. This means that events from a.foo.com will be available from b.foo.com. Cookies have the limitation of not being able to store a lot of data, especially if your stored page views are long.

• Local storage, which allows to store much more information client side, but has the drawback of not being able to access data across multiple top level domains.

• Session storage, which has roughly the same limitation and capability as Local storage, except that it is cleared when the web browser tab is closed.

By default, the local storage option will automatically be chosen as the default storage, unless manually specified.
