Smart Focus Tracker

A production-ready React hook for comprehensive focus tracking and form analytics. Designed for UX teams, product managers, and developers who need precise user interaction insights.

Overview

Smart Focus Tracker provides real-time monitoring of user focus patterns on form elements, enabling data-driven optimization of user experiences. Built with TypeScript and zero external dependencies, it seamlessly integrates into existing React applications.

Key Features

• Zero Dependencies: Lightweight implementation with no external libraries
• TypeScript Native: Full type safety and IntelliSense support
• Performance Optimized: Minimal overhead with efficient event handling
• Production Ready: Thoroughly tested and enterprise-grade
• Framework Agnostic: Works with any React-based application
• Real-time Analytics: Millisecond-precision tracking

Installation

npm install smart-focus-tracker

yarn add smart-focus-tracker

pnpm add smart-focus-tracker

Quick Start

import { useFocusTracker, FocusData } from "smart-focus-tracker";

export function ContactForm() {
  const { report } = useFocusTracker();

  const handleSubmit = async (event: React.FormEvent) => {
    event.preventDefault();

    // Generate analytics report before submission
    const focusAnalytics = report();

    // Send analytics to your backend
    await submitForm(formData, focusAnalytics);
  };

  return (
    <form onSubmit={handleSubmit}>
      <input id="email" type="email" placeholder="Email address" />
      <input id="password" type="password" placeholder="Password" />
      <button type="submit">Sign In</button>
    </form>
  );
}

API Documentation

useFocusTracker()

The primary hook for focus tracking functionality.

Returns:

• report(): Record<string, FocusData> - Generates current focus analytics

Type Definitions

interface FocusData {
  focusTime: number; // Total focus duration in milliseconds
  focusCount: number; // Number of focus events
  lastFocused: number | null; // Timestamp of last focus event
}

Usage Examples

Basic Implementation

import { useFocusTracker } from "smart-focus-tracker";

function RegistrationForm() {
  const { report } = useFocusTracker();

  const analyzeUserBehavior = () => {
    const analytics = report();
    console.log("User focus patterns:", analytics);
  };

  return (
    <form>
      <input id="username" placeholder="Username" />
      <input id="email" placeholder="Email" />
      <button type="button" onClick={analyzeUserBehavior}>
        Analyze Behavior
      </button>
    </form>
  );
}

Advanced Analytics Integration

import { useFocusTracker, FocusData } from "smart-focus-tracker";

function CheckoutForm() {
  const { report } = useFocusTracker();

  const trackFieldDifficulty = () => {
    const analytics = report();

    // Identify potentially problematic fields
    const problematicFields = Object.entries(analytics)
      .filter(([_, data]) => data.focusCount > 3 || data.focusTime > 10000)
      .map(([fieldId]) => fieldId);

    if (problematicFields.length > 0) {
      // Send UX insights to analytics service
      trackEvent("form_friction_detected", {
        fields: problematicFields,
        analytics,
      });
    }
  };

  return (
    <form onSubmit={trackFieldDifficulty}>
      <input id="cardNumber" placeholder="Card Number" />
      <input id="expiryDate" placeholder="MM/YY" />
      <input id="cvv" placeholder="CVV" />
    </form>
  );
}

Implementation Requirements

• Elements must have unique id attributes for tracking
• Only focusable elements (inputs, textareas, selects, etc.) are monitored
• Compatible with React 16.8+ (hooks support required)

Sample Analytics Output

{
  "email": {
    "focusTime": 23.40,

  },
  "password": {
    "focusTime": 0.93,
    "focusCount": 3,
    "lastFocused": 2025-03-07 12:31:59
  },
  "confirmPassword": {
    "focusTime": 8.92,
    "focusCount": 4,
    "lastFocused": null
  }
}
