🚀 Repoxy

Repoxy is a lightweight, experimental reverse proxy / API gateway written in Rust.
It’s currently a WIP / learning project, built as part of my journey into Rust, systems programming, and network infrastructure.

---

✨ Goals

• High-performance reverse proxy built on async Rust (tokio, hyper, axum)
• Configurable routing (via repoxy.toml)
• TLS termination (via rustls)
• API Gateway features:
  • ✅ Path-based routing
  • 🔒 JWT / API key authentication
  • ⚡ Rate limiting
  • 📊 Observability (logging, metrics, tracing)
• Load balancing (round-robin / least-connections)
• Extensible middleware (filters, request rewriting, etc.)

---

📦 Installation

Clone the repo and build with Cargo:

git clone https://github.com/fuunshi/repoxy.git
cd repoxy
cargo build --release

Run:

cargo run

🛠️ Example Config (repoxy.toml)

[[routes]]
path = "/api/users"
backends = ["http://localhost:5000", "http://localhost:5001"]

[[routes]]
path = "/api/orders"
backends = ["http://localhost:6000"]

---

📍 Roadmap

• Minimal reverse proxy (forward requests → backend)
• Configurable routes via TOML
• JWT & API key validation
• Rate limiting per client
• TLS termination
• Load balancing
• Prometheus metrics & tracing
• Plugin system (maybe WASM-based)

⚠️ Disclaimer

This project is a work in progress (WIP) and part of my learning journey in Rust. Expect breaking changes, missing features, and experiments. Not production-ready (yet).
