Snowplow JavaScript Tracker 2.17.0 - with cookieless tracking

We’re pleased to announce the Snowplow JavaScript Tracker version 2.17.0!

This release includes support for the new cookieless tracking now available in the Stream Collector v2.1.0 announced yesterday.

This builds on our earlier support that allowed for client side anonymisation using the anonymous tracking features. From 2.17.0, the JavaScript tracker will also be able to inform the collector if it should return a cookie and capture the users IP address.

Note: You must be using Stream Collector 2.1.0 or above, for the server side anonymisation of the Snowplow JavaScript Tracker 2.17.0 to work or events will fail to send whilst in the server side anonymisation mode.

When initialising the tracker, you can enable it:

snowplow("newTracker", "sp", "{{collector_url_here}}", {
  appId: "my-app",
  stateStorageStrategy: "none",
  anonymousTracking: { withServerAnonymisation: true }
  contexts: {
    webPage: true,
  }
});

Then you can turn it off and start tracking user information (e.g. when a user accepts a cookie banner):

snowplow('disableAnonymousTracking', 'cookieAndLocalStorage');

You can also turn it back on later if required:

snowplow('enableAnonymousTracking', { withServerAnonymisation: true });
