Xchange.js

Xchange.js is an MIT-licensed JavaScript library that wraps APIs from six cryptocurrency exchanges: Bitfinex, Bitstamp, Coinbase, BTC-e, Kraken and OkCoin. It supports client-side and server-side use, with callbacks or ES6 Promises, and includes a Bitfinex BTC/USD ticker example.

Understand the project

Practical overview

When it fits

Use Xchange.js when a JavaScript project needs to call one of its listed exchange APIs, especially for ticker data. The README's concrete example is a Bitfinex BTC/USD query.

Who it is for

  • JavaScript developers building applications that query cryptocurrency exchange APIs.
  • Developers who want a shared wrapper for ticker and other documented exchange API calls.

Documented uses

  • Request ticker data, such as the demonstrated Bitfinex BTC/USD spot-price response.
  • Use exchange API calls from client-side or server-side JavaScript.
  • Choose callback-based or Promise-based handling.
Before you choose

Requirements & limits

The repository provides npm installation instructions and lists an MIT license.

  • The README lists six supported exchanges: Bitfinex, Bitstamp, Coinbase, BTC-e, Kraken and OkCoin.
  • The documented ticker example is specifically for Bitfinex BTC/USD.
  • Authenticated transaction operations such as buying and selling are described as roadmap work, not current functionality.

Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.

Source-based practical guide

Install Xchange.js and make a Bitfinex ticker call

Set up the package and use the README's callback example to request the Bitfinex BTC/USD ticker.

Before you start

  • Node.js and npm
  • A JavaScript project

Steps

  1. Install the package with the command below.

    Documented command
    npm install xchange.js

  2. Import xchange from xchange.js in the project.

  3. Call xchange.bitfinex.ticker with {symbol: 'BTCUSD'} and a callback that handles the error and response.

Expected outcome

The documented example prints the returned response when the callback reports no error.

Guide limitations

  • The example demonstrates a Bitfinex ticker query only.
  • The documentation does not establish dashboard implementation or normalized responses across exchanges.
  • Authenticated buy and sell operations are described as roadmap work.
