Simple Node.js Reverse Proxy

A basic reverse proxy server built with Node.js that forwards HTTP GET requests to predefined upstream servers.

Core Features

• Basic HTTP request forwarding
• YAML-based configuration
• Multi-worker process support
• Path-based routing with pattern matching
• Static upstream server definitions
• Technical Implementation
• Uses Node.js cluster for worker processes
• Configuration managed through YAML
• Path matching with regex patterns
• Single request type (GET) support
• Random worker selection for request handling

Quick Start

# Install dependencies
npm install

# Start server with config
npm start -- --config config.yaml

Configuration Example

server:
  listen: 8000
  workers: 4
  
  upstreams:
    - id: upstream1
      url: jsonplaceholder.typicode.com

  rules:
    - path: /**
      upstreams:
        - upstream1

Limitations

• Only supports GET requests
• No load balancing algorithms
• No health checks
• No request/response transformation
• No SSL/TLS support
• No request queueing
• No retry mechanisms
