Quick Start

1. Installation

• Install The Conviva JavaScript Agent SDK using either npm or yarn:

npm install @convivainc/conviva-js-agent-tracker

yarn add @convivainc/conviva-js-agent-tracker

Note: For script-based integrations, refer Conviva JS Script ECO SDK for guidelines.

2. Initialization

• Import the required packages into your project:

import {
	convivaAppTracker,
	setUserId,
	trackPageView,
} from '@convivainc/conviva-js-agent-tracker';

• Initialize The Conviva JavaScript Agent SDK:

Note: It is recommended to initialize the tracker as early as possible during the DOM load sequence, such as in App.js.

convivaAppTracker({
	appId: 'YOUR_APP_NAME',
	convivaCustomerKey: 'YOUR_CUSTOMER_KEY',
	appVersion: '1.1.0',
});

YOUR_APP_NAME - A string value that uniquely identifies your app across platforms. For example: "WEB App", "LGTV App".

YOUR_CUSTOMER_KEY - A string to identify a specific customer account. Use different keys for dev and prod. Find them in Pulse under My Profile (Conviva login required).

appVersion - Set app version in string format.

3. Set the User ID

User ID is a unique string identifier to distinguish individual viewers. If using Conviva Video Sensor, match it with the Viewer ID. Note: Set the User ID as soon as Conviva sensor is initialized so that none of the events are missed from User's timeline.

setUserId('replace_me_by_the_userId');

4. Report Page View

trackPageView() should be called after the page is considered "loaded" by your application—that is, when content is rendered and ready for user interaction. Avoid calling it too early (e.g., before the main content or layout is visible), as this may result in incomplete timing data.

What defines a "page change"? This depends on your app type:

For MPAs: Every full page reload is a new page. For SPAs: A new page is usually identified by URL path or route changes.

Developers should trigger pageview() based on what they define as a meaningful navigation or view transition in their application.

By default, when trackPageView() is called, the Page Title is set using document.title. However, you can override this by passing a custom title in the trackPageView() API:

// Uses document.title as the Page Title
trackPageView();

// Pass a custom Page Title
trackPageView({ title: 'Custom Page Title' });

Note: The Web (JS/React) SDK does not collect page views if the trackPageView() API is not explicitly called during a navigation event. As a result, corresponding metrics (such as Page Views, Avg Perceived Page Load Time, Avg Largest Contentful Paint Time) will be missing from the Pulse dashboard. Conviva does not support auto-collection of missing page views.

After steps 1–4, verify auto-collected events in the validation dashboard . (Conviva login required)

5. Cleanup API

The cleanup() API is used to completely remove all Conviva tracker listeners, timers, and resources from the current page. This is useful for single-page applications (SPAs) or when you need to fully reset or remove the tracker instance (for example, during logout, navigation, or teardown).

What does cleanup do?

• Removes all event listeners (network, click, visibility, etc.)
• Clears all timers and intervals used by the tracker
• Disables error and click tracking
• Cleans up network request tracking
• Resets internal tracker state and removes the tracker instance

Usage Example:

import { cleanup } from '@convivainc/conviva-js-agent-tracker';

// Remove all Conviva tracker listeners and resources
cleanup();

Note: The cleanup API is not supported in older browsers (Chrome < 66, Mozilla < 57, Safari < 12.1).

More Features

Track Custom Event

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

name - Name of the custom event

data - Any type of data in JSON format.

import { trackCustomEvent } from '@convivainc/conviva-js-agent-tracker';

let customData = {
	identifier1: 'test',
	identifier2: 1,
	identifier3: true,
};

trackCustomEvent({
	name: 'Custom Event Name',
	data: customData,
});

Set Custom Tags

Custom Tags are global tags applied to all events and persist throughout the application lifespan, or until they are removed.

Set the custom tags:

import { setCustomTags } from '@convivainc/conviva-js-agent-tracker';

let customTagsData = { tagKey1: 'tagValue1', tagKey2: 1, tagKey3: true };
setCustomTags(customTagsData);

Clear previously set custom tags:

import { unsetCustomTags } from '@convivainc/conviva-js-agent-tracker';

// Remove custom tags tagKey2 & tagKey3
let customTagsData = ['tagKey2', 'tagKey3'];
unsetCustomTags(customTagsData);

Error Reporting

Uncaught exceptions and unhandled rejections are automatically collected and enabled by default. To report caught exceptions or other errors, use the following API:

import { trackError } from '@convivainc/conviva-js-agent-tracker';

try {
	//...
} catch (error) {
	trackError({
		message: 'Cannot get user object',
		filename: 'shop.js',
		error: error, // Passing the caught error object.
	});
}

Client ID Synchronization

When using multiple Conviva JavaScript Agent SDK instances across different environments (e.g., subdomains of the same root domain), the Client ID will be shared automatically using local storage & cookies

To ensure consistency, the SDK provides the following advanced APIs for manual synchronization. These APIs are intended for developers who require fine-grained control over Client ID management across multiple instances. Use Cases:

• Synchronizing Client ID between a mobile app and WebView.

Note: The Conviva JavaScript Agent SDK utilizes local storage & cookies to cache some data.

• getClientId() – Retrieves the current Client ID
• setClientId(clientId) – Sets a specific Client ID

Retrieve the Client ID

import {
	convivaAppTracker,
	getClientId,
} from '@convivainc/conviva-js-agent-tracker';

convivaAppTracker({
	appId: 'YOUR_APP_NAME_AS_STRING',
	convivaCustomerKey: 'CONVIVA_ACCOUNT_CUSTOMER_KEY',
	appVersion: '1.1.0',
});

// Always call getClientId() after initializing convivaAppTracker()
clientId = getClientId();

Set the Client ID

import {
	convivaAppTracker,
	getClientId,
} from '@convivainc/conviva-js-agent-tracker';

// Always call setClientId() before initializing convivaAppTracker() to set a specific clientId
setClientId(clientId);

convivaAppTracker({
	appId: 'YOUR_APP_NAME_AS_STRING',
	convivaCustomerKey: 'CONVIVA_ACCOUNT_CUSTOMER_KEY',
	appVersion: '1.1.0',
});

Meta Tags Collection

This feature enables tracking of meta tags from the <head> section of an HTML page based on the provided configuration.

Example meta tags in an HTML Page:

<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>

Configure Meta Tags Tracking

To collect meta tag data, you need to define the metaTagsTracking configuration during SDK initialization.

Example Configuration:

convivaAppTracker({
	appId: 'YOUR_APP_NAME_AS_STRING',
	convivaCustomerKey: 'CONVIVA_ACCOUNT_CUSTOMER_KEY',
	appVersion: '1.1.0',
	configs: {
		metaTagsTracking: {
			tags: [
				{
					key: 'name', // Target meta tags with "name" attributes
					value: 'content', // Extract their "content" values
				},
				{
					key: 'property', // Target meta tags with "property" attributes
					value: 'content', // Extract their "content" values
					condition: ['title', 'locale'], // Optional: Filter by specific property values
				},
			],
		},
	},
});

Set Device Metadata

deviceMetadata is an object containing key-value pairs for predefined values, such as DeviceType and DeviceCategory, as well as additional properties like DeviceBrand, DeviceManufacturer, and DeviceModel.

Conviva automatically collects deviceMetadata for Web apps and mobile browsers. However, for devices like set-top boxes, smart TVs, gaming consoles, and others, you will need to manually set the deviceMetadata.

Example of setting deviceMetadata:

import {
	convivaAppTracker,
	ConvivaDeviceMetadata,
} from '@convivainc/conviva-js-agent-tracker';

const deviceMetadata: ConvivaDeviceMetadata = {
	DeviceBrand: 'Samsung',
	DeviceManufacturer: 'Samsung',
	DeviceModel: 'UTU7000',
	DeviceType: 'SmartTV',
	OperatingSystemName: 'Tizen',
	OperatingSystemVersion: '8.0',
	DeviceCategory: 'SAMSUNGTV',
	FrameworkName: 'Angular',
	FrameworkVersion: '8.0.0',
};

convivaAppTracker({
	appId: 'YOUR_APP_NAME_AS_STRING',
	convivaCustomerKey: 'CONVIVA_ACCOUNT_CUSTOMER_KEY',
	appVersion: '1.1.0',
	deviceMetadata: deviceMetadata,
});

WebSocket message stream	When WebSocket events occur (open, close, send, receive, error) for real-time communication tracking.

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 App Experience Metrics page in the Learning Center.

Auto-collection of SSE Events (EventStream via Fetch API)

The Conviva JavaScript Agent SDK supports auto-collection of Server-Sent Events (SSE) when they are delivered as an eventstream response via the Fetch API. This enables tracking of real-time server-push events in modern web applications.

• Current Coverage:
  • Primary events of type CONVERSATION_MESSAGE are automatically collected and tracked.
  • First token events (CONVERSATION_STREAMING_TOKEN) are tracked when chat begins.
  • Added support to count Tokens shared between start and end of chat.
  • Extra events can be configured via extraEvents array (e.g., CONVERSATION_CLOSE_CONVERSATION, CONVERSATION_PARTICIPANT_CHANGED).

No extra configuration is required—if your application receives SSEs as an eventstream through Fetch, supported events will be tracked automatically according to your remote configuration.

Auto-collection of WebSocket Events

The Conviva JavaScript Agent SDK supports auto-collection of WebSocket events for real-time communication tracking. This enables comprehensive monitoring of WebSocket connections, messages, and errors in modern web applications.

• Current Coverage:

  • Connection Events: WebSocket open and close events with connection details (URL, codes, reasons).
  • Message Events: Both client-sent messages (conviva_ws_send) and server-received messages (conviva_ws_server).
  • Error Events: WebSocket errors with comprehensive error details, network information, and browser context.

• Event Details:

  • All WebSocket activity is emitted as a single event name: conviva_ws_message.
  • The specific WebSocket phase is provided via the event attribute with one of: open, close, send, server, error.
  • open: Tracks when WebSocket connections are established
  • close: Tracks connection closures with status codes and reasons
  • send: Tracks outgoing messages with URL and message data
  • server: Tracks incoming server messages with URL and parsed data
  • error: Tracks errors with detailed error information and network context

No extra configuration is required—if your application uses WebSocket connections, events will be tracked automatically according to your remote configuration.

Limitations

Clicks

The collection of all types of clicks is automatically supported, including those from standard HTML elements as well as elements created using React, Angular, and Vue frameworks. We also offer an experimental remote configuration specifically for click events, aiming to dynamically add support for non-standard or unsupported frameworks. For further assistance, please contact the Conviva support team. Note: preventDefault and stopPropagation will prevent the auto-collection of button and link click events.

Migration of Pulse dimensions for clicks

Starting with version v1.1.2 of the SDK, the attribute keys for click events have been updated. If you are using v1.1.1 or earlier and currently mapping elementText, you must update your configuration when upgrading to v1.1.2 or later. Specifically, update the mapping in DPI Activation by mapping elementText to text, then redeploy to apply the changes.

To ensure metrics reflect the updates, please review and update your event/metric mappings in DPI Activation if you are using any of the following attributes:

<=v1.1.1	>=v1.1.2
elementType	elementType
elementText	text
elementName	elementName
elementValue	value
elementId	id
elementClasses	class

network_request

This feature supports tracking network requests triggered within the application using XMLHttpRequest and the Fetch API.

Request and Response Body Collection:

Collected only when:

• Size is < 10KB.
• Response body is type JSON.
• Content-type contains "json" or equals any of "text/plain", "text/javascript", "application/javascript", "text/html"
• Response Type is not "opaque"

Request and Response Header Collection:

Collected only when:

• The server is provisioned with "Access-Control-Expose-Headers:".
• Response Type is not "opaque"

Clean up

"cleanup" api support is not available in older browsers(Chrome: < 66, Mozila: < 57, Safari: < 12.1)
