Usage

Privacy Tracking Consent

Starting with version 7.x, telemetry.js has support for privacy tracking consent. The host application can decide to enable this behavior passing .requireConsent in the options passed into the constructor, along with an optional IPrivacySettings object. The example below shows this structure.

Users can consent to the following types of "tracking":

• Performance: Allows only application performance information to be sent and stored
• Functional: Allows for functional information to be stored, like perferences, past searches etc
• Targeting: Allows for user targeting information to be sent

When requireConsent is passed, and no userPrivacySettings is sent, telemetry.js operates as though the user has opted out of all tracking. This is expected behavior as per GDPR.

When userPrivacySettings.performance: true, and the Esri amazon pin-point tracker is configured as a plugin, it will be initialized.

For Hub Sites (and some other platform applications) customers can configure additional 3rd party tracking systems (Google Analytics, Adobe, SiteImprove). In order for those trackers to be enabled, the end-user must opt into performance, functional and targeting, because we do not know or control what the 3rd party trackers are doing, so we must assume they are tracking all three.

In Browser

import { Telemetry } from '@esri/telemetry';

// create options object
const opts = {
  requireConsent: true, // if your app requires privacy consent, set this to true
  plugins: [list of plugins goes in here]
};
// Host app should load user privacy settings from localStorage or cookies
const storedSettings = window.localStorage.getItem('esri_privacy_settings');
if (storedSettings) {
  opts.userPrivacySettings = JSON.parse(storedSettings);
} else {
  // this is optional, as telemetry.js will construct the same thing
  // if requiteConsent: true and not settings are passed in
  opts.userPrivacySettings = {
    id: '3ef...', // create some unique id
    timestamp: Date.now(),
    accepted: false, // user has not actually set these, so this is false
    performance: false, // all set to false by default 
    functional: false, 
    targeting: false,
  }
}
// create the telemetry instance
const telemetry = new Telemetry(opts);

await telemetry.init();
// now it is ready to go

In Server

Since this is done on the server, it is not able to take user privacy settings into account. Thus, it is discouraged to inject script tags on the server, as tracking is likely to start before the host application actually boots and can apply the user privacy settings.

import { Telemetry } from '@esri/telemetry';

// create options object
const opts = {
  plugins: [list of plugins goes in here]
};
// create the telemetry instance
const telemetry = new Telemetry(opts);
// in server
const scriptTags = telemetry.getScriptTags();
// now inject script tags into html page before sending it down
