bitfinex-api

Bitfinex cryptocurrency exchange API wrapper for Node.js

Installation

yarn add bitfinex-api

Usage

Clients for both the v1 REST API and v1 streaming WebSocket API are included. Private endpoints as indicated in the API docs require authentication with an API key and secret key.

Example usage:

import BitfinexAPI from 'bitfinex-api';

const restClient = new BitfinexAPI({ key, secret });
const websocketClient =
  new BitfinexAPI.WebsocketClient({ key, secret });

restClient.getOrderBook('BTCUSD', { limit_asks: 10, limit_bids: 10 })
  .then(console.log)
  .catch(console.error);

websocketClient.openSocket(() => {
  websocketClient.addMessageListener(data =>
    doSomethingCool(data)
  );
  websocketClient.subscribeToChannel({
    channel: 'trades',
    pair: 'BTCUSD',
  })
})

// The methods are bound properly, so feel free to destructure them:
const { getTicker } = restClient;
getTicker('btcusd')
  .then(data =>
    console.log(`Last trade: $${data.last} / BTC`)
  )
