How It Works

1. Frontend sends parallel requests to 13 API endpoints
2. Backend queries LeetCode's GraphQL API, caches responses for 5 minutes
3. Analysis engines compute readiness scores, weakness patterns, roadmaps, and study plans
4. Results are rendered with Chart.js charts and animated UI components

🚀 Quick Start

Local Development

# Clone
git clone https://github.com/dasouvik122005/leetTrack.git
cd leetTrack

# Install dependencies
pip install flask requests

# Run
python api/index.py

Open http://localhost:5000 and enter any LeetCode username.

Deploy to Vercel

# Install Vercel CLI
npm i -g vercel

# Deploy
vercel

Or connect this repo directly in the Vercel Dashboard — it auto-detects the config.

Chrome Extension

1. Open chrome://extensions/
2. Enable Developer mode
3. Click Load unpacked → select the extension/ folder
4. Update DASHBOARD_URL in popup.js and content.js to your Vercel URL
