J it only takes a minute:
I'm trying to get started with the MEAN stack. And I'm following this tutorial:
I have made it until the Test Our Server section. Here
// modules =================================================
var express = require('express');
= express();
var mongoose= require('mongoose');
// configuration ===========================================
// config files
var db = require('./config/db');
var port = process.env.PORT || 8080; // set our port
mongoose.connect(db.url); // connect to our mongoDB database (uncomment after you enter in your own credentials in config/db.js)
app.configure(function() {
app.use(express.static(__dirname + '/public'));
// set the static files location /public/img will be /img for users
app.use(express.logger('dev'));
// log every request to the console
app.use(express.bodyParser());
// have the ability to pull information from html in POST
app.use(express.methodOverride());
// have the ability to simulate DELETE and PUT
// routes ==================================================
require('./app/routes')(app); // configure our routes
// start app ===============================================
app.listen(port);
// startup our app at http://localhost:8080
console.log('Magic happens on port ' + port);
// shoutout to the user
exports = module.exports =
// expose app
When I run
nodemon server.js
I get this error
app.configure(function() {
TypeError: Object function (req, res, next) {
app.handle(req, res, next);
} has no method 'configure'

It simply says app has no method configure(I guess). But when I delete the configure part and run it again, it works.(This mean app has .listen method, so it is an express object.)
I have tried with both node and nodemon. And I couldn't figure it out. Thank you for your time.

The configure method has been removed from express as of version 4.0.0 (including 4.0.0-rc2). See the changelog at

Tom in his blog post
provides examples of how to convert from using app.configure in express version 3.x to removing it in express version 4.0.
For convenience I added the code example below.
Version 3.x
// all environments
app.configure(function(){
app.set('title', 'Application Title');
// development only
app.configure('development', function(){
app.set('mongodb_uri', 'mongo://localhost/dev');
// production only
app.configure('production', function(){
app.set('mongodb_uri', 'mongo://localhost/prod');
Version 4.0
// all environments
app.set('title', 'Application Title');
// development only
if ('development' == app.get('env')) {
app.set('mongodb_uri', 'mongo://localhost/dev');
// production only
if ('production' == app.get('env')) {
app.set('mongodb_uri', 'mongo://localhost/prod');
