To integrate the JavaScript SDK with your website, place the following code snippet in the <head> section of your website.
<script type="text/javascript">
!function(){var e=window.hightouchevents=window.hightouchevents||[];e.methods=["load","page","track","identify","alias","group","ready","reset","getAnonymousId","setAnonymousId"],e.factory=function(t){return function(){e.push([t].concat(Array.prototype.slice.call(arguments)))}};for(var t=0;t<e.methods.length;t++){var r=e.methods[t];e[r]=e.factory(r)}e.loadJS=function(e,t){var r=document.createElement("script");r.type="text/javascript",r.async=!0,r.src="https://cdn.hightouch-events.com/js/latest/events.min.js";var a=document.getElementsByTagName("script")[0];a.parentNode.insertBefore(r,a)},e.loadJS(),
e.load(<WRITE_KEY>,<DATA_PLANE_URL>,{configUrl: <CONTROL_PLANE_URL>}),
e.page()}();
</script>The above snippet lets you integrate the SDK with your website and load it asynchronously to keep your page load time unaffected.
To load the events SDK synchronously, you can refer to the minified or non-minified versions of the code in the following sections:
<script>
hightouchevents=window.hightouchevents=[];for(var methods=["load","page","track","identify","alias","group","ready","reset","getAnonymousId","setAnonymousId"],i=0;i<methods.length;i++){var method=methods[i];hightouchevents[method]=function(a){return function(){hightouchevents.push([a].concat(Array.prototype.slice.call(arguments)))}}(method)}hightouchevents.load(<WRITE_KEY>,<DATA_PLANE_URL>, {configUrl: <CONTROL_PLANE_URL>}),hightouchevents.page();
</script>
<script src="https://cdn.hightouch-events.com/js/latest/events.min.js"></script><script>
hightouchevents = window.hightouchevents = [];
var methods = [
'load',
'page',
'track',
'identify',
'alias',
'group',
'ready',
'reset',
'getAnonymousId',
'setAnonymousId',
];
for (var i = 0; i < methods.length; i++) {
var method = methods[i];
hightouchevents[method] = (function (methodName) {
return function () {
hightouchevents.push([methodName].concat(Array.prototype.slice.call(arguments)));
};
})(method);
}
hightouchevents.load(YOUR_WRITE_KEY, DATA_PLANE_URL, {
configUrl: <CONTROL_PLANE_URL>,
});
//For example,
//hightouchevents.load("1Qb1F3jSWv0eKFBPZcrM7ypgjVo", "http://localhost:8080", {
// configUrl: "http://localhost:8080,
//});
hightouchevents.page();
</script>
<script src="https://cdn.hightouch-events.com/js/latest/events.min.js"></script>In all the above versions, there is an explicit page call at the end. This is added to ensure that whenever the SDK loads in a page, a page call is sent. You can remove this call completely or modify it with the extra page properties to suit your requirement. You can also add page calls in your application in places not tied directly to page load, e.g., virtual page views, page renders on route change such as in SPAs, etc.
To integrate and initialize the JavaScript SDK, you will need the source write key and the data plane URL.
Although we recommend using the snippets mentioned above to use the JavaScript SDK with your website, you can also use this NPM module to package the library directly into your project.
To install the SDK via npm, run the following command:
npm install @ht-sdks/events-sdk-js --saveNote that this NPM module is only meant to be used for a browser installation. If you want to integrate with your Node.js application, refer to the Node.js SDK.
IMPORTANT: Since the module exports the related APIs on an already-defined object combined with the Node.js module caching, you should run the following code snippet only once and use the exported object throughout your project:
import * as hightouchevents from "events-sdk-js";
hightouchevents.ready(() => {
console.log("we are all set!!!");
});
hightouchevents.load(<WRITE_KEY>, <DATA_PLANE_URL>);
export { hightouchevents };You can also do this with ES5 using the require method, as shown:
var hightouchevents = require("events-sdk-js");
hightouchevents.load(<WRITE_KEY>, <DATA_PLANE_URL>);
exports.hightouchevents = hightouchevents;The APIs exported by the module are:
loadreadyidentifyaliaspagetrackgroupresetgetAnonymousIdsetAnonymousId
| Browser | Supported Versions |
|---|---|
| Safari | v7 or later |
| IE | v10 or later |
| Edge | v15 or later |
| Mozilla Firefox | v40 or later |
| Chrome | v37 or later |
| Opera | v23 or later |
| Yandex | v14.12 or later |
If the SDK does not work on the browser versions that you are targeting, verify if adding the browser polyfills to your application solves the issue.
The identify call lets you identify a visiting user and associate them to their actions. It also lets you record the traits about them like their name, email address, etc.
A sample identify() call is shown below:
hightouchevents.identify(
'12345',
{
email: '[email protected]',
},
{
page: {
path: '',
referrer: '',
search: '',
title: '',
url: '',
},
},
() => {
console.log('in identify call');
},
);In the above example, the user-related information like the userId and email is captured.
There is no need to call
identify()for anonymous visitors to your website. Such visitors are automatically assigned ananonymousId.
The track call lets you record the customer events, i.e. the actions that they perform, along with any associated properties.
A sample track call is shown below:
hightouchevents.track(
'test track event GA3',
{
revenue: 30,
currency: 'USD',
user_actual_id: 12345,
},
() => {
console.log('in track call');
},
);In the above example, the track method tracks the user event ‘test track event GA3’ and information such as the revenue, currency, anonymousId.
You can use the
trackmethod to track various success metrics for your website like user signups, item purchases, article bookmarks, and more.

Look for run scripts in the
package.jsonfile for getting the browser minified and non-minified builds. The builds are updated in thedistfolder of the directory. Among the others, some of the important ones are:npm run build:browser: This outputs events.min.js.npm run build:npm: This outputs events-sdk-js folder that contains the npm package contents.npm run build:integration:all: This outputs integrations folder that contains the integrations.
We use rollup to build our SDKs. The configuration for it is present in
rollup-configsfolder.
- For adding or removing integrations, modify the imports in
index.jsunder thesrc/integrationsfolder.
The JS SDK can be used in Chrome Extensions with manifest v3, both as a content script or as a background script service worker.
