binance-api-node

A complete API wrapper for the Binance API.

Note: This wrapper uses Promises, if they are not supported on your, you might want to add a polyfill for them.

Installation

yarn add binance-api-node

Getting started

Import the module and create a new client. Passing api keys is optional only if you don't plan on doing authenticated calls. You can create an api key here.

import Binance from 'binance-api-node'

const client = Binance()

// Authenticated client, can make signed calls
const client2 = Binance({
  apiKey: 'xxx',
  apiSecret: 'xxx',
})

client.time()
  .then(time => console.log(time))

Every REST method returns a Promise, making this library async await ready. Following examples will use the await form, but that's totally up to you.
