Node.js server.get（）TypeError：未定义不是函数

Question

var express = require('express'),
    http = require('http'),
    app = express(),
    server = http.createServer(app),
    io = require('socket.io').listen(server), //pass a http.Server instance
    fs = require('fs');

server.listen(8008);

// routing
server.get('/', function (req, res) {
  res.sendfile(__dirname + '/chat.html');
});

I have this code which creates a server. When I run this I get the following error: TypeError: undefined is not a function

server.get('/', function (req, res) {
       ^
TypeError: undefined is not a function
    at Object.<anonymous> (C:\Users\rexhi\Desktop\private_mess\app.js:11:8)

    at Function.Module.runMain (module.js:501:10)
    at startup (node.js:129:16)

What is wrong here? I'm new to Node.

Answer 1

The .get(req,res) function belongs to an instance of express . Thus, you should do:

app.get('/', function (req, res) {
    ..
});

Answer 2

It looks to me like you are trying to use express to handle your routing, if that is the case then you want to use app.get() not server.get() . So in your case something like

app.get('/', function (req, res) {
  res.sendfile(__dirname + '/chat.html');
});

Take a look at the express routing reference for more info - http://expressjs.com/guide/routing.html

Answer 3

Use app.get() instead of server.get()

app.get('/', function (req, res) {
  res.sendfile(__dirname + '/chat.html');
});
