I have an express application, and a websocket script.
I create the server and spinup the express app in a www.js file.

The problem I'm facing is that, I'm not able to instantiate the websocket inside the www.js file.

Here is the www.js

....
const server = http.createServer(app);
server.listen(port);
server.on("error", onError);
server.on("listening", onListening);
....

Here is the websocket.js

const WebSocket = require('ws');

const wss = new WebSocket.Server( port: 8080 );

wss.on('connection', function connection(ws) 
 ws.on('message', function incoming(message) 
 console.log('received: %s', message);
 );

 ws.send('something');
);

I know the line const wss = new Websocket.Server( port: 8080 ); creates the websocket instance...but I want to be able to create this instance in www.js file and all the logic for websocket in a seperate file.

node.js express ws

Pass the http server instance to the websocket server,

const wss = new Websocket.Server( server: server );

---

If you want to separate it as a single modules to a file,

const WebSocket = require('ws');


const initWSServer = (server) => 
 const wss = new WebSocket.Server( server: server);

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

 ws.on('message', function incoming(message) 
 console.log('received: %s', message);
 );

 ws.send('something');

 );


module.exports = 
 initWSServer

Then,

const server = http.createServer(app);
server.listen(port);
server.on("error", onError);
server.on("listening", onListening);

const ws_server = require('./websocket.js');
ws_server.initWSServer(server);
