Is it possible to use node.js, express, and socket.io together with ipv6 compatibility

Below is a snippet of my code:

var gzippo = require('gzippo');

var app = require('express').createServer()
  , io = require('socket.io').listen(app);

io.enable('browser client gzip');
io.set('transports', [
    'websocket'
]);

app.use(gzippo.staticGzip(__dirname + '/'));

app.listen(8001);

app.get('/', function (req, res) {
  res.sendfile(__dirname + '/main2.html');
});

io.sockets.on('connection', function (socket) {...});

I am using gzippo for gzip, express for the http server, and socket.io for websocket functionality.

Currently, the code works properly with requests from an ipv4 address.

How can I modify it to listen for requests from my ipv6 address?

Answer №1

It seems that there is an issue with socket.io failing to connect due to difficulties in parsing ipv6 URLs. More information can be found at https://example.com/socketio-issue260
