Javascript Question

TypeError: app.get is not a function

I'm trying to use express in a prototype

function ioServer() {


module.exports = ioServer;

ioServer.prototype.start = function() {
var app = require('express')
var http = require('http').Server(app)
var io = require('socket.io')(http)

app.get('/', function(req, res) {
var outPut = ""
res.sendFile(__dirname + './client/index.html')

http.listen(3000, function(port) {
console.log('Listening on port, ' + 3000)

But when I use it It throws the error
TypeError: app.get is not a function
When I remove the prototype part it works.

Your app should be an instance of express.

For example, you could include it like this:

var app = require('express')();
