# React Insight

A powerful React performance monitoring component that helps you identify and fix performance issues in your React applications.

![React Insight Demo](demo-screenshot.png)

## Features

- 🔍 Real-time performance analysis
- 📊 Comprehensive performance metrics
- 🎯 Specific improvement suggestions
- 🚀 Easy integration
- 📱 Responsive design

## Installation

It is recommended to start the localhost on chrome for this package, as per some of it's features are built on experimental API that exists only on chrome

```bash
npm install react-insight
# or (PREFERED)
yarn add react-insight
```

## Quick Start
Wrap your application with the `PerformanceMonitor` component:

```jsx
import React from 'react';
import  'react-insight/dist/index.css'
import { PerformanceMonitor } from 'react-insight';

function App() {
  return (
    <PerformanceMonitor>
      {/* Your app content */}
      <div>Your React application</div>
    </PerformanceMonitor>
  );
}
```

## Performance Metrics

React Insight monitors several key performance metrics:

- **DOM Size**: Tracks the number of DOM elements and their depth
- **Memory Usage**: Monitors JavaScript heap size
- **Active Timers**: Counts active intervals and timeouts
- **Event Listeners**: Tracks the number of event listeners
- **Interaction Delay**: Measures UI responsiveness
- **Network Requests**: Monitors pending network requests
- **Layout Shifts**: Detects potential layout instability
- **Image Optimization**: Checks for missing alt attributes and large images

## Performance Score Calculation

The performance score is calculated based on multiple factors:

- DOM size (elements count and depth)
- Memory usage
- Active timers and event listeners
- Interaction delay
- Network requests
- Layout shifts
- Image optimization
