mandelbrot

Generic adapters for trading, runs in Node.js and in the browser.

Used in sunbeam and cheesebox.

Supports:

Wallets

ws, wu parsing and snapshot handling

Orderbooks

R0 and P1 book handling.

Reference implementation

sunbeam is heavily relying on Mandelbrot and has a nice documentation

You can find the implemented code, with EOSfinex specific extensions here: https://github.com/bitfinexcom/sunbeam/tree/master/lib

Example

This example connects to a Websocket server. When a wallet is sent with ws and wu, it parsed them, stores the current state and logs the result.

const MB = require('mandelbrot')
const Wallet = MB.BaseWallet

class CustomExchangeAdapter extends MB.WsBase {
  constructor (opts) {
    opts.Wallet = Wallet
    super(opts)
  }
}
const ws = new CustomExchangeAdapter({
  url: 'wss://websocket.example.com'
})

ws.on('message', (m) => {
  console.log(m)
})

ws.on('error', (m) => {
  console.error(m)
})

ws.on('open', (m) => {
  ws.onManagedWalletUpdate({}, (res) => {
    console.log('onManagedWalletUpdate', res)
  })
})

ws.open()
