Can not Run Node.js server file
Question
I am new to Node.js. I have my NodeServer.js file which has below code.
var express = require("express");
var app = express();
var port = 60000;
var io = require('socket.io').listen(app.listen(port));
console.log("Listening on port " + port);
io.sockets.on('connection', function (socket) {
socket.emit('message', { message: 'welcome to the chat' });
socket.on('send', function (data) {
io.sockets.emit('message', data);
});
});
When I run this from command prompt , by below code
D:\Path to my application>Node NodeServer.js
It shows message like
info - socket.io started
Listening on port 60000
But when I try to connect to this port from browser by http://127.0.0.1:60000 , it shows me below error in command prompt
D:\Path to my application\node_modules\expres
s\lib\application.js:119
this._router.handle(req, res, function(err) {
^
TypeError: Cannot call method 'handle' of undefined
What am I Doing wrong?
Above issue is solved:
Below is my EDIT
Below is my client Script
$(document).ready(function () {
var socket = io.connect('http://127.0.0.1:60000');
});
Below is my desing

I have solved my issue by below steps.
- I moved my ClientScript to one specific folder(Scripts).(Say my client Script's name is NodeClient.js)
- I removed
app.get("/", function(req,res){ your logic should go here });function from Server script. - added below code
app.use(express.static(__dirname + '/Scripts'));
Now it is working the way I want. I don't know whether it is right way or not, but it is working now for me.

change the following line
var io = require('socket.io').listen(app.listen(port));
by
var io = require('socket.io').listen(port);
app.listen(port) returns an object but we have to run the socket.io and express in same port. To do that simply pass the port variable
