I am trying to implement Socket IO with my angular Js project. I am new into this, please help.
This is my server.js file
var express = require('express');
var path = require('path');
var app = express();
var server = require('http').Server(app);
var io = require('socket.io')(server);
var port = 8080;
app.use(express.static(path.join(__dirname, "app")));
io.on('connection'), function(socket){
console.log('new connection made');
}
server.listen(port, function(){
console.log('Listening to port '+ port);
})
I have copied the socket.io.js file from socket.io-client and put it in my lib folder. So my index.html has
<script src="lib/js/socket.io.js"></script>
//all other includes required
<body>
//code here
</body>
heres is the error I get to see when I execute nodemon server.js
[nodemon] starting `node server.js`
events.js:216
throw new TypeError('"listener" argument must be a function');

Small typo on your code.Try this :
var express = require('express');
var path = require('path');
var app = express();
var server = require('http').Server(app);
var io = require('socket.io')(server);
var port = 8080;
app.use(express.static(path.join(__dirname, "app")));
io.on(('connection'), function(socket){
console.log('new connection made');
})
server.listen(port, function(){
console.log('Listening to port '+ port);
})
Remember, io.on(event,cb) is a function call that registers the cb function to the event.
