connect 2 websockets ws and socket.io

I'm getting data from a web page with websocket but I need to deploy it with socketIO to client. In my server.js client connects with socketio well but after that data(line1 line2) can't comes properly, always I need to restart server 2-3 times.Then it comes.

Here is my declerations

var server = require('http').Server(app);
var io = require('socket.io')(server);
const WebSocket = require('ws')
const wss = new WebSocket('gettingDataAdress');

io.on('connection', function (socket) {
console.log("client connected");


wss.on('open', () =>
console.log("send processing");
//line1
)
wss.on('message', () =>
console.log("getting message processing");
//line2
)


After restarting my server.js 2-3 times it can comes to line1 and line2 , it can't directly.However whenever I comment the socketio Part(I mean only websocket working) it works perfect.How can I do that ? Thank you

You are using two different websockets ws and socket.io. Use only one to connect to the client and subscribe to the coming messages

ws

socket.io

io.on('connection', function (socket) {
console.log("client connected");


socket.on('open', () =>
console.log("send processing");
//line1
)
socket.on('message', () =>
console.log("getting message processing");
//line2
)


const WebSocket = require('ws');

const ws = new WebSocket('url');

ws.on('open', () =>
//do processing
);

ws.on('message', () =>
//do processing
);


wanted to write a comment but had no reputation to write, so decide write on here. sorry!

If you want to subscribe, rather use socket.io-client. However, socket-io itself is not a proper library to subscribe wss.

socket.io-client

socket-io

wss

actually, Socket.IO is not a WebSocket implementation, it has its own protocol which may use a WebSocket connection to transmit data
-darrachequesne-(most contributor of socket-io client library)

so If you get data from wss page, then use ws library and spread it by socket-io. I believe that what you are doing is pretty fine. might need to fix a bit though.

Connecting to GDAX websocket api using socket.io with webpack
there is similar question to get data from ws.
