Proxy Server

A lightweight HTTP proxy server built with Express.js that forwards requests to any configurable target URL.

Purpose

This proxy server acts as an intermediary between clients and target servers, enabling:

• Cross-Origin Request Handling: Bypasses CORS restrictions by serving as a same-origin endpoint
• API Gateway Functionality: Routes requests to different backend services through a single entry point
• Development Testing: Allows local development against remote APIs without CORS issues
• Request Forwarding: Transparently forwards all HTTP methods (GET, POST, PUT, DELETE) with original headers and body content

Quick Setup

1. Install dependencies: pnpm install
2. Create .env file:

PORT=1337
PROXY_URL=https://your-target-server.com

3. Start server: node index.js

Usage

The server receives requests at http://localhost:1337 and forwards them to the configured PROXY_URL. For example:

• Request to: http://localhost:1337/api/users
• Forwards to: https://your-target-server.com/api/users

All request data, headers, and methods are preserved during forwarding. The response from the target server is returned to the original client.

Configuration

Set these environment variables in your .env file:

• PORT: Server port (default: 1337)
• PROXY_URL: Target server URL (required)
