Sylph

Sylph is a lightweight, modular reverse proxy server built using Node.js. It is designed to be extensible, with support for routing, caching, and middleware — all configurable for different use cases like load balancing or request inspection.

This project is primarily aimed at developers looking to integrate a custom proxy into their server-side infrastructure or development workflows.

Features

• 🛣️ Routing – Define and manage custom routes using a Trie-based router.
• 💾 Caching – In-memory caching to reduce duplicate network requests.
• 🧩 Middleware Support – Add request/response middlewares for inspection, logging, etc.
• ⚖️ Load Balancing (optional) – Configurable support for balancing across multiple targets.
• 🔧 Simple Setup – Small footprint and minimal configuration needed.

Use Cases

• Proxy API requests during frontend development
• Add caching or auth to upstream services
• Debug and inspect HTTP traffic
• Load balance across multiple internal services

Getting Started

To use Sylph in your project:

npm install @ankit-1204/sylph

const { proxy } = require('@ankit-1204/sylph');
