Events SDK Javascript

Installation

npm install @ht-sdks/events-sdk-js --save

Note 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 repository.

IMPORTANT: You should run the following code snippet only once and use the exported object throughout your project (e.g. Node module caching):

import * as analytics from "@ht-sdks/events-sdk-js";
analytics.ready(() => {
  console.log("we are all set!!!");
});
analytics.load(<WRITE_KEY>, <DATA_PLANE_URL>, {configUrl: <CONTROL_PLANE_URL> });
export { analytics };

You can also do this with ES5 using the require method, as shown:

var analytics = require("@ht-sdks/events-sdk-js");
analytics.load(<WRITE_KEY>, <DATA_PLANE_URL>, {config:Url: <CONTROL_PLANE_URL>});
exports.analytics = analytics;

Exported APIs

The APIs exported by the module are:

• load
• ready
• identify
• alias
• page
• track
• group
• reset
• getAnonymousId
• setAnonymousId

Supported browser versions

| 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.

Identifying users

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:

analytics.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 (and other contextual info) is captured.

There is no need to call identify() for anonymous visitors to your website. Such visitors are automatically assigned an anonymousId.

Tracking user actions

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:

analytics.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 track method to track various success metrics for your website like user signups, item purchases, article bookmarks, and more.

The ready API

There are cases when you may want to tap into the features provided by the end-destination SDKs to enhance tracking and other functionalities. The JavaScript SDK exposes a ready API with a callback parameter that fires when the SDK is done initializing itself and the other third-party native SDK destinations.

An example is shown in the following snippet:

analytics.ready(() => {
  console.log('we are all set!!!');
});
