HTTP Proxy Server

A lightweight Backend-for-Frontend (BFF) proxy server built in Rust, designed to proxy REST, GraphQL and tRPC requests.

🔍 What is a BFF (Backend-for-Frontend)?

A Backend-for-Frontend (BFF) is a server that sits between your frontend application and backend services. It provides several advantages over reverse proxies, specifically tailored to the frontend's needs.

---

✅ Problems Solved

• CORS Issues
  Eliminates cross-origin resource sharing problems as this will work as backend to backend communication .

• Performance
  Built in Rust for ultra-high throughput (100k+ requests/second).

• Security
  Minimal attack surface via a tiny Alpine-based container (0 vulnerabilities).
