ezbot-javascript

The easiest way to interact with ezbot via JS (node and browser). For ease of use, our Javascript library wraps Snowplow's Browser Tracker (BSD-3 License).

Getting Started

How to use it in your project via NPM (recommended)

Install

npm install @ezbot-ai/javascript-sdk

Use

import { initEzbot } from '@ezbot-ai/javascript-sdk';

await initEzbot(yourProjectId);

How to use it in your project via <script> tag

Install

<script src="https://cdn.ezbot.ai/web-snippets/ezbot.min.js"></script>

Use

await ezbot.initEzbot(yourProjectId);

How to develop this library

npm install
npm run fix
npm run test:unit

Sending Events

Send reward events to ezbot to tune the model and improve the quality of the recommendations.

We currently support two types of rewardUnits: count and dollars. If you send a reward with dollars as the rewardUnits, we will use it to calculate the total dollars per session. If you send a reward with count as the rewardUnits, we will optimize for total count of reward events per session.

We only support one type of rewardUnits per project today.

Via NPM

import {
  initEzbot,
  trackPageView,
  trackRewardEvent,
  startActivityTracking,
  makeVisualChanges,
} from '@ezbot-ai/javascript-sdk';

await initEzbot(yourProjectId);
startActivityTracking({
  /** The minimum time that must have elapsed before first heartbeat */
  minimumVisitLength: 2,
  /** The interval at which the callback will be fired */
  heartbeatDelay: 2,
});
trackPageView();
trackRewardEvent({ key: 'your_key', reward: 1, rewardUnits: 'count' });
trackRewardEvent({ key: 'another_key', reward: 100, rewardUnits: 'dollars' });
makeVisualChanges(); // Optional. If the variable is a visual change, it will be applied.

Via <script> tag

await ezbot.initEzbot(yourProjectId);
ezbot.startActivityTracking({
  /** The minimum time that must have elapsed before first heartbeat */
  minimumVisitLength: 2,
  /** The interval at which the callback will be fired */
  heartbeatDelay: 2,
});
ezbot.trackPageView();
ezbot.trackRewardEvent({ key: 'your_key', reward: 1, rewardUnits: 'count' });
ezbot.trackRewardEvent({
  key: 'another_key',
  reward: 100,
  rewardUnits: 'dollars',
});
ezbot.makeVisualChanges(); // Optional. If the variable is a visual change, it will be applied.

NextJS

Since we don't yet support server-side rendering, you'll need to notate your component with "use strict" and use the React Hook useEffect to initialize ezbot. If you're using Strict Mode, you'll need to use a ref to prevent multiple initializations in your development environment. Strict Mode does not affect production.

'use client';

import { initEzbot } from '@ezbot-ai/javascript-sdk';
import { useEffect, useRef } from 'react';

// your component
export default function Home() {
  const ezbotInit = useRef(false);
  useEffect(() => {
    if (ezbotInit.current) {
      return;
    }
    initEzbot(7);
    ezbotInit.current = true;
  }, []);
}

Using Predictions

Change your user's experience based on the predictions made by ezbot. For now, you'll need to write custom code to use the predictions.

Below is just an example. After initializing ezbot, you can use the window.ezbot.predictions object to access the predictions.

Example Predictions Response

{
  "holdback": false,
  "predictions": [
    {
      "key": "hero_headline",
      "type": "basic",
      "version": "0.1",
      "value": "Automated Experimentation with AI",
      "config": null
    },
    {
      "key": "hero_cta",
      "type": "basic",
      "version": "0.1",
      "value": "Check It Out",
      "config": null
    }
  ]
}
