Socket not working when I do a pub build

I fixed some issues which may relate to this issue, you can give it a try. (remember to run pub upgrade first), and I also make a test case with a timer to demonstrate the problem you encountered, but it works well for me on both dartium or browser (compiling to js) environment.

Hi,

I have been having the same problem, but slightly different.

On pub serve things are working fine, but on pub build, locally I would get a few 400 errors but eventually succeed to connect. Below is a screenshot:

I am also deploying my app on digital ocean VPS and over there I would get a huge number of 400 errors(with same response body), and finally connect after 1 or 2 minutes. Below is a screenshot of network activities on VPS.

My server is written in node:

var app = express()
var server = http.createServer(app);
server.listen(port);
var io = require('socket.io').listen(server);

I am using namespaces also, for each client:

var socketPath = '/' + req.session.user.username
io.of(socketPath).on('connection', function (socket) {
    ...
}

Client:

String namespace = 'http://localhost:5000' + socketPath;
print('connecting to $namespace');
socket = IO.io(namespace);
socket.on('connect', (_) {
        print('connected to $namespace');
        ....
}

As far as I can see there's very little custom config used. Could you please take a look as this? I can discuss more in detail. This lib is critical for my project, so please help.

Thanks,
Nick

This issue is fixed in https://github.com/rikulo/socket.io-dart, so you should upgrade them by running pub upgrade.
