🌐 CORS Proxy Server

A lightweight and secure CORS Proxy built with Node.js, Express, and Axios, designed to bypass CORS restrictions when making client-side API requests. Supports infinite request/response timeout, caching, rate-limiting, and logging.

✨ Features

• 🚀 Proxy any HTTP(S) request using ?url=... query parameter
• ♾ Infinite request/response timeout (no timeouts for long-running requests)
• 📦 Built-in in-memory caching for GET requests (configurable TTL)
• 🔒 Rate limiting to prevent abuse (configurable)
• 📝 Winston-based logging to file with timestamps
• 🌍 CORS enabled (allows all origins by default)

📦 Installation

git clone https://github.com/Jasurbek2208/corsproxyserver.git
cd corsproxyserver
npm install

🚀 Usage

Start the proxy server:

npm run start

By default, the server runs on port 2208 (or from .env).

Example Request

# Proxy a public API request
curl "http://localhost:2208/?url=https://jsonplaceholder.typicode.com/posts/1"

Example in JavaScript (fetch)

fetch("http://localhost:2208/?url=https://jsonplaceholder.typicode.com/posts/1")
  .then(res => res.json())
  .then(console.log)

⚙ Configuration

Environment variables (.env):

Variable	Default	Description
PORT	2208	Server port
RATE_LIMIT_WINDOW_MS	60000	Rate limit window (ms)
RATE_LIMIT_MAX	100	Max requests per window per IP
CACHE_TTL	10	GET cache TTL (seconds)
LOG_LEVEL	info	Logging level (error, warn, info, debug)
LOG_FILE	proxy.log	Log file path

🔒 Notes

• Use responsibly; this server exposes a raw proxy to any URL.
• Consider deploying behind authentication if running in production.
