Bitfinex API Node.js Client

Official Node.js client library for the Bitfinex cryptocurrency exchange API. Version 8.0.0 supports REST v2 and WebSocket v2/v1 APIs, providing real-time trading, order management, and market data. Requires Node >=18.0. Key differentiators: official library with full coverage of Bitfinex endpoints, built-in WebSocket management, automatic reconnection, and order tracking via event emitters. Actively maintained with regular releases. Alternative to community libraries like ccxt, but Bitfinex-specific and supports advanced features like margin trading and funding.
