Install

npm install --save tealium-tracker

How to use

First, you'll need to inject the utag script onto the page.

If using Gatsby, see gatsby-plugin-tealium-utag.

Once utag is globally available, initialize the Tealium tracker.

import initTealiumTracker from "tealium-tracker"; const { trackPageLoad, trackEvent } = initTealiumTracker();

This gives you access to trackPageLoad and trackEvent functions that you can call with the data object (a.k.a. the data layer).

// When page loads trackPageLoad(myDataLayer); // this will call utag.view(myDataLayer) // When button is clicked trackEvent(myDataLayer); // this will call utag.link(myDataLayer)

Note

Since the utag script loads asynchronously, you might encounter the case where trackPageLoad or trackEvent are called before the utag script finished loading.

In this case, tealium-tracker will put the utag calls in a queue and flush the queue once the utag script is loaded.

For this to work, you must emit a "utag-loaded" event when the utag script is loaded.

<script type="text/javascript"> (function(a,b,c,d){ a='//tags.tiqcdn.com/utag/[ACCOUNT]/[PROFILE]/[ENV]/utag.js'; b=document;c='script';d=b.createElement(c); d.onload=function() { b.dispatchEvent(new Event("utag-loaded")); }; d.src=a;d.type='text/java'+c;d.async=true; a=b.getElementsByTagName(c)[0];a.parentNode.insertBefore(d,a) })(); </script>

If using Gatsby, gatsby-plugin-tealium-utag takes care of emitting this event.

Validation

When schema is passed, tealium-tracker will automatically validate the data object against the schema before calling utag.view or utag.link.

const { trackPageLoad, trackEvent } = initTealiumTracker({ schema });

We use Ajv to perform the validation, so schema can be something like:

const schema = { type: "object", required: ["site", "page"], properties: { site: { type: "string", minLength: 1 }, page: { type: "string", minLength: 1 }, button: { type: "string", minLength: 1 } } };

Debug mode

To output useful information to the console, do:

const { trackPageLoad, trackEvent } = initTealiumTracker({ debugMode: true });
