I'm following official restify guide to use socketio with restify.
api.js
var mongoose = require('mongoose');
var restify = require('restify');
var fs = require('fs');
var server = restify.createServer({
name: 'myapp',
version: '1.0.0'
});
var io = require('socket.io')(server);
server.get('/', function indexHTML(req, res, next) {
fs.readFile(__dirname + '/sockettest.html', function (err, data) {
if (err) {
next(err);
return;
}
res.setHeader('Content-Type', 'text/html');
res.writeHead(200);
res.end(data);
next();
});
});
io.on('connection', function(socket){
console.log('a user connected');
});
sockettest.html
<html>
<script src="https://cdn.socket.io/socket.io-1.3.7.js"></script>
<script>
var socket = io();
</script>
</html>
When I browse to localhost:3000 I'm getting this error:
myapp listening at http://[::]:3000
_http_outgoing.js:350
throw new Error('Can\'t set headers after they are sent.');

Can you please tell me what is I'm missing?

Using
var io = require('socket.io')(server.server);
instead of
var io = require('socket.io')(server);
solved my problem.
