Quanta.js

Quanta.js is a lightweight analytics SDK for web applications. It's a JavaScript port of the Quanta Swift SDK, providing the same powerful analytics capabilities for websites and web applications.

Features

• Simple event tracking with custom parameters
• Automatic page view tracking
• User identification and session management
• A/B testing support
• Revenue tracking
• Lightweight and performant

Installation

Option 1: Script Tag

Add the following script tag to your HTML:

<script src="https://js.quanta.tools/app/{YOUR_APP_ID}.js"></script>

Replace {YOUR_APP_ID} with your Quanta application ID.

Option 2: NPM

npm install quanta.tools

Then import it into your application:

import { Quanta } from "quanta.tools";

// Initialize with your app ID
Quanta.initialize("YOUR_APP_ID");

// Track events
Quanta.log("button_click");

Usage

Basic Event Tracking

// When using the script tag:
window.quanta.log("button_click");
window.quanta.log("product_view", { product_id: "123", category: "shoes" });
window.quanta.logWithRevenue("purchase", 29.99, { product_id: "123" });

// When using npm:
import { Quanta } from "quanta.tools";
Quanta.log("button_click");
Quanta.log("product_view", { product_id: "123", category: "shoes" });
Quanta.logWithRevenue("purchase", 29.99, { product_id: "123" });

View Tracking

By default, Quanta automatically tracks page views when the page loads and when navigation occurs (through history API). You can disable this behavior using configuration attributes.

User Identification

Quanta assigns each user a unique ID on their first visit. You can access or set this ID:

// Get the current user ID
const userId = Quanta.getId();

// Set a custom user ID
Quanta.setId("user-123");

Configuration

You can configure Quanta.js behavior using data attributes on the script tag:

<script
  src="https://js.quanta.tools/app/{YOUR_APP_ID}.js"
  data-skip-first-view-event
  data-enable-debug-logs
></script>

Available attributes:

| Attribute | Description | | ---------------------------------- | --------------------------------------------------------- | | data-skip-first-view-event | Skip tracking the initial page view | | data-skip-navigation-view-events | Skip tracking navigation events after the first page view | | data-skip-all-view-events | Disable all automatic page view tracking | | data-enable-debug-logs | Enable debug logging to the console |

Browser Compatibility

Quanta.js works in all modern browsers that support:

• localStorage
• fetch API (polyfilled for older browsers)
• History API

Data Privacy and Compliance

Quanta.js is designed with privacy in mind. User IDs are generated as random UUIDs and then shortened for efficiency. No personal information is collected unless explicitly passed in event parameters. Quanta is GDPR compliant.

Best Practices

1. Keep event names consistent across your application
2. Use clear, descriptive event names and parameter keys
3. Don't include sensitive or personally identifiable information in event parameters
4. Use revenue tracking for all monetization events
