kucoin-node-api

This is an open source project created to utilize the Kucoin v2 API to support automated, algorithmic trading. The project was made and tested for Node 8.0+.

There are no guarentees towards the stability or effectiveness of this project. Comments, contributions, stars and donations are, however, all welcome.

Installation

npm install kucoin-node-api

Alternatively, you can clone/download the repository and import into your project by file path.

Getting Started

To begin using the API wrapper, require it, create a config object that contains your API key, Secret key and Passphrase provided by Kucoin. Then run the custom init() function with your config object as a parameter. If you are only using Public endpoints, the config object only requires the environment key/value pair.

Example code is as follows:

const api = require('kucoin-node-api')

const config = {
  apiKey: 'xXXXXXXXXXXXXXXXXXXXXxxxxxxxxxxxxxxxxxxxxxXXX',
  secretKey: 'xxxxxxxxXXXXXXXXXXXXXxxXXXXXXXXXXXXXxxxXXX',
  passphrase: 'xxxxxx',
  environment: 'live'
}

api.init(config)

Using the API Wrapper

Once the API wrapper object is created, you can call any of the associated functions. They will return a Promise which can be utlized with .then/.catch or async/await. Note that the Promise based approach will return directly whereas the async/await approach requires calling the function.

Simple example:

// Promise based approach for getting account information (private & signed)
api.getAccounts().then((r) => {
  console.log(r.data)
}).catch((e) => {
  console.log(e)
})

// Async/Await get account info example (private & signed)
async function getAccounts() {
  try {
    let r = await api.getAccounts()
    console.log(r.data)
  } catch(err) {
    console.log(err)
  } 
}

This approach allows for more complex multi-call asynchronous functionality, especially useful for automated trading.

Market Endpoint (Public)

Public endpoints do not require an API Key, Secret Key or API Passphrase.

Websockets

The websocket component of the API wrapper is utilized by initializing websockets based on topics that match Kucoin endpoints. These include:

'ticker'
'allTicker'
'symbolSnapshot'
'marketSnapshot'
'orderbook'
'match'
'fullMatch' (optional - private)
'orders' (private)
'balances' (private)

To initialize a websocket, provide the paramaters and an event handler. A simple example is as follows:

// Parameters 
params = {
  topic: enum (see above)
  symbols: array (ignored if not required by the endpoint, single array element if single, multiple if desired)
}

// Public streaming websocket for the orderbook of the provide symbol(s)
api.initSocket({topic: "orderbook", symbols: ['KCS-BTC']}, (msg) => {
  let data = JSON.parse(msg)
  console.log(data)
})

// Private streaming websocket for account balances
api.initSocket({topic: "balances"}, (msg) => {
  let data = JSON.parse(msg)
  console.log(data)
})

The event handler can be programmed to manipulate/store the returned websocket stream data as desired.
