Allow me to specify port AND hostname on .listen()

[andyuk]

Hi,

It's important in my app that it listens on a specific IP address. Having the option to pass the hostname would solve this.

Currently I can only use:
.listen(port)

I am working around this by creating a HTTP server myself.

How about supporting:

var options = {
port: 80,
hostname: 'localhost'
};
.listen(options)

Supporting a config option would mean it could still be backwards compatible.

Thanks,
Andy

try

var io = require('socket.io');
var server = http.createServer();
server.listen(8080);
var socket = io.listen(server,{origins: "localhost"});

This would only accept connections from localhost

My current workaround is this:

var io = require('socket.io');
var server = http.createServer();
server.listen(8080, 'localhost');
var socket = io.listen(server);

That makes sure the server binds to the IP address of localhost.

OK - perhaps we can close this. It's not a big issue. :)

I just tried switching from ws to socket.io - using the code you are suggesting here. I'm having problems though.

My previous code, works perfectly:

var WebSocketServer = require('ws').Server;
var wss = new WebSocketServer({port: 8080,host:"not.your.business.com"});
wss.on('connection', function(ws) {
    ws.on('message', function(message) {
        console.log('got message');
      });
  });

Socket.io code, does not work:

var http = require('http');
var io = require('socket.io');
var server = http.createServer();
server.listen(8080, 'not.your.business.com');
var socket = io.listen(server);
socket.on('connection', function (socket) {
    socket.on('message', function () {
      console.log("got message");
     });
  });

This only outputs "debug - destroying non-socket.io upgrade" when trying to connect. What am I doing wrong? I tried the latter code in various flavours without success.
