kucoin-futures-node-api

Just a KuCoin Futures API version of https://github.com/escwdev/kucoin-node-api/.

Installation

npm install kucoin-futures-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. Create an instantiation of the class 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-futures-node-api')

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

const apiLive = new api()
apiLive.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)
apiLive.getAccountOverview().then((r) => {
  console.log(r.data)
}).catch((e) => {
  console.log(e))
})

// Async/Await get account info example (private & signed)
async function getAccountOverview() {
  try {
    let r = await apiLive.getAccountOverview()
    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'
• 'tickerv2'
• 'orderbook'
• 'execution'
• 'fullMatch'
• 'depth5'
• 'depth50'
• 'market'
• 'announcement'
• 'snapshot'
• 'ordersMarket' (private)
• 'orders' (private)
• 'advancedOrders' (private)
• 'balances' (private)
• 'position' (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)
apiLive.initSocket({topic: "orderbook", symbols: ['KCS-BTC']}, (msg) => {
  let data = JSON.parse(msg)
  console.log(data)
})

// Private streaming websocket for account balances
apiLive.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.
