🚀 Setup Instructions

1️⃣ Clone the repository

git clone https://github.com/yourusername/proxy-tester-dashboard.git
cd proxy-checker

2️⃣ Install dependencies

For frontend:

cd frontend
npm install

For backend:

cd backend
npm install

3️⃣ Run backend

cd backend
npm run dev

By default runs on http://localhost:4000

4️⃣ Run frontend

cd frontend
npm start

By default runs on http://localhost:3000

🔧 Backend Notes

• Uses Express server with /test endpoint
• Supports parsing & auto-detecting proxy formats (HTTP, SOCKS4, SOCKS5)
• Measures latency per proxy test
• Uses socks package for SOCKS proxy handling
• Automatically retries multiple protocols for unknown types

⚠ Proxy Format Accepted

• ip:port
• http://ip:port
• socks4://ip:port
• socks5://ip:port

Example input:

http://91.107.154.214:80
socks4://192.111.137.34:18765
133.18.234.13:80

📊 Architecture Summary

• Proxy list submitted from frontend.
• Frontend tests proxies sequentially (concurrent workers) by sending individual HTTP POST requests to backend.
• Backend tests each proxy and returns result with type and latency.
• Results table updates live.
