Node.js Proxy Server

HTTP proxy server that forwards requests to http://localhost:20001.

We use this proxy because the Rubix node does not handle CORS. The proxy adds the required CORS headers so that browser-based requests work without errors.

Features

• HTTP/HTTPS request forwarding
• CORS support
• Request logging
• Health check endpoint
• Error handling
• Configurable target URL

Installation

npm install

Usage

Development:

npm run dev

Production:

npm start

Custom port:

PORT=8080 npm start

Configuration

Default target: http://localhost:20001. Change TARGET_URL in server.js to modify.

Endpoints

• GET /health: Returns server status
• All other routes: Forwarded to target URL with method, headers, body, and query string preserved

Example

# Health check
curl http://localhost:3000/health

# Forward request
curl http://localhost:3000/api/data
# Goes to http://localhost:20001/api/data

Logging

Requests and proxy operations logged to console.

Error Handling

• Proxy errors return JSON responses
• Target unavailability handled with error messages
