/binance-api-node

:chart: A complete and heavily tested wrapper with typings for the Binance API.

Primary LanguageJavaScript

binance-api-node build cover bnb

A complete API wrapper for the Binance API.

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

For PRs or issues, head over to the source repository.

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',
  getTime: xxx, // time generator function, optional, defaults to () => Date.now()
})

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

If you do not have an appropriate babel config, you will need to use the basic commonjs requires.

const Binance = require('binance-api-node').default

Every REST method returns a Promise, making this library async await ready. Following examples will use the await form, which requires some configuration you will have to lookup.
