How to send data from server to client through WS

Short Description:

I want to send data from server.js to my client side (react.js)
I got running BOT from backend and I want to send the data in the client side through WS, so I wrap the binance.websockets to WS
Error if I hit refresh multiple times in the browser

Platform:

windows 10

node version:

9.5.0

code

const SocketServer = require('ws').Server;
const binance = require('node-binance-api');
const wss = new SocketServer({ server });

wss.on('connection', function connection(ws) {

 binance.websockets.depthCache(symbol, (symbol, depth) => {
   ...
   if(ws.readyState === 1 ){
    ws.send(JSON.stringify(binanceData)); 
   }
  ...
  })

});

result
