Application Analytics for Conviva JavaScript Sensor

Use Application Analytics to autocollect events, track application specific events and state changes, and track users anonymously.

Usage

To use the video sensor, download the Core JavaScript SDK file (version 4.5.6 or above) from Conviva JavaScript Sensor Integration and unzip the downloaded file.

Download

To use the application sensor, use convivaAppTracker.js file from this repository

Initialization

Add the following script to the HTML head section of your website:

Below 2 arguments are passed to function one is the global scope in which your app is loaded and other is the namespace by which you want to referr the app tracker.

<script type="text/javascript">

(function(p, i) {
    if (!p[i]) {
        p.GlobalSnowplowNamespace = p.GlobalSnowplowNamespace || [];
        p.GlobalSnowplowNamespace.push(i);
        p[i] = function() {
            (p[i].q = p[i].q || []).push(arguments)
        };
        p[i].q = p[i].q || [];
    }
}(window, "apptracker"));
</script>

#### include convivaAppTracker.js as script tag.
<script src= "<<URL / Path to convivaAppTracker.js>>"></script>

Initialize the tracker

Init the SDK with appId, customerKey and optional parameters.

• appId: set this to your understandable application name, reflecting the platform and brand of your app. As an example: "WEB App", "LGTV Web App".
• convivaCustomerKey: the unique string identifier for your Conviva account. Provided by Conviva / can be obtained in the Conviva Pulse dashboard.
• appVersion: set app version in string format.

window.apptracker('convivaAppTracker',  {
    appId: 'YOUR_APP_NAME_AS_STRING',
    convivaCustomerKey: 'CONVIVA_ACCOUNT_CUSTOMER_KEY',
    appVersion: "1.1.0",
    contexts: {
        performanceTiming: true
    },
});

Note:- Eco Sensor utilises localstorage to cache some data.

Set the user id (viewer id)

// Set this after initializing the tracker and before autocollection
window.apptracker('setUserId','replace_me_by_the_userId');

Report Page View for tracking in-app page navigations.

By default document.title is set as page title but you can also pass custom page title details in trackPageView.

window.apptracker('trackPageView'); // default page title is document.title
window.apptracker('trackPageView', {"title": "Custom Page Title"});

Enable autocollection

window.apptracker('enableLinkClickTracking');
window.apptracker('enableButtonClickTracking');

Enable Error Tracking

To enable automatic tracking of run-time exceptions in the application, use the following API:

window.apptracker('enableErrorTracking');

Alternatively, you could report exceptions manually using the following API:

window.apptracker('trackError', {
    message: 'Cannot get user object',
    filename: 'shop.js',
    error: exceptionObj //Exception object containing properties describing the exception.
});

Custom event tracking to track your application specific events and state changes

Use trackCustomEvent() API to track all kinds of events. This API provides 2 fields to describe the tracked events.

name - Name of the custom event. (Mandatory)

data - Any type of data in json format.

The following example shows the data in JSON format.

let custom_data = {
                    "identifier1": "test",
                    "identifier2": 1,
                    "identifier3":true
                  };

window.apptracker('trackCustomEvent', {
    name: "custom_event_name",
    data: custom_data
});

Conviva Video Events to App Insight

We need minimum of the Video Sensor Core SDK Version of 4.5.13 to be in a stage to delegate the events:

v4.5.13

4.5.13 (27/DEC/2022) - Supports broadcasting video events to Conviva Eco SDKs to consume. For non App Insights users, there is no impact. - We only send following fields from video events into Eco events (name, sid, iid, clid, st, cen, ced, an).

Setting / Unsetting Custom tags to report your application specific data.

Use setCustomTags() API to set all kinds of tags (key value pairs). This API provides 1 argument that accepts data in JSON Format to describe the tags.

The following example shows the implementation of setting custom tags. In this example we have 3 different tags tagKey1, tagKey2, tagKey3 with 3 different values.

let customTagsToSet = {"tagKey1": "tagValue1","tagKey2": 1,"tagKey3":true};
window.apptracker('setCustomTags', customTagsToSet);

Use unsetCustomTags() API to unset or remove that were already set. This API provides 1 argument to describe an array of tag keys to unset.

The following example shows the implementation of unset or remove custom tags.

let customTagsToUnset = ['tagKey2', 'tagKey3'];
window.apptracker('unsetCustomTags' customTagsToUnset);

AutoCollection of Network Request made using XMLHttpRequest and fetch api

This feature supports to track the Network Requests triggerred with in application using XMLHttpRequest and fetch api Note: This collection is disabled by default, reach out to Conviva Team enabling the tracking.

Here are some of the granular details/limitations of the feature:

• Response and Request Body atributes are collected only when the:
  • size is < 10kb and the content-length is available
  • response body is type json and content-type is "json", "text/plain", "text/javascript" or "application/javascript"
• Response and Request Headers are collected only when the:
  • server is provisioned with "Access-Control-Expose-Headers:"*

AutoCollection of Meta tags from HEAD section of HTML page

This feature supports to track the Meta tags from HEAD section of HTML page based on the config provided.

metaTagsTracking is the config to collect Meta tags and can be provided as part of tracker Initialization under configs field.

Structure of metaTagsTracking config

//for below meta tags
<HTML>
    <HEAD>
    <meta name="keywords" content="HTML, CSS, JavaScript">
    <meta name="description" content="Free Web tutorials for HTML and CSS">
    <meta name="author" content="John Doe">
    <meta http-equiv="refresh" content="30">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <meta property="site_name" content="goole.com">
    <meta property="title" content="Sample app">
    <meta property="description" content="Tv series content">
    <meta property="locale" content="es_ES">
    <meta property="type" content="video">
    </HEAD>
</HTML>

//Example config to collect all name attributes and it's value and few certain property attributes and it's value.
 window.apptracker('convivaAppTracker',  {
    appId: 'YOUR_APP_NAME_AS_STRING',
    convivaCustomerKey: 'CONVIVA_ACCOUNT_CUSTOMER_KEY',
    appVersion: "1.1.0",
    contexts: {
        performanceTiming: true
    },
    configs:{
        metaTagsTracking: {
          "tags":
            [
              {
                "key": "name", //mandatory //here key sepcifies what attributes tag to collect
                "value": "content", //mandatory //value specifies the value .
              },
              {
                "key": "property",
                "value": "content",
                "condition": ["title", "locale"] // optional //value of attributes placed in key to collect 
              },
              ...
            ]
        }
    }
});

Auto Ingestion of "traceparent" header to network requests

This feature supports to ingest "traceparent" header into network requests based on the config provided. Note: This ingestion is disabled by default, reach out to Conviva Team enabling the tracking.

Auto-collected Events

Conviva provides a rich set of application performance metrics with the help of autocollected app events, such as button_click, and network_request.

Event	Occurrence	Notes
network_request	after receiving the network request response	only supports xmlHttpRequest/fetch
page_ping	Max X and Y scroll positions difference comparing to the last event
application_error	when an error occurrs in the application
button_click	on the button click callback	only if element is type button or button tag \n preventDefault and stopPropagation prevents to auto collect these events
link_click	on the link click callback	only if element is anchor tag \n preventDefault and stopPropagation prevents to auto collect these events
application_background	when visibility state change to hidden
application_foreground	when visibility state change to visible
Largest Contentful Paint	timing information about the largest image or text paint before user input on a web page	Context
First App Launch	First time launch in the browser	Custom Tag Context

To learn about the default metrics for analyzing the native and web applications performance, such as App Crashes, Avg Screen Load Time, and Page Loads, refer to the ECO Metrics page in the Learning Center.

Note:- To integrate Conviva App Experience with web applications having multiple HTML pages, add the aforementioned instructions to each HTML page.
