I am following a tutorial in which i am setting up a node.js server and mongoDB database. I am at a point where i need to start npm, but this is the error it returns

C:\Users\Jay\IdeaProjects\nodetest1>npm start

> [email protected] start C:\Users\Jay\IdeaProjects\nodetest1
> node ./bin/www


    module.js:340
        throw err;

I have followed the tutorial thoroughly and am quite new to node/mongo so if anyone knows how to help, i'd appreciate it.

Here is my app.js code

var express = require('express');
var path = require('path');
var favicon = require('static-favicon');
var logger = require('morgan');
var cookieParser = require('cookie-parser');
var bodyParser = require('bodyParser');

//Database
var mongo = require('mongoskin');
var db = mongo.db("mongodb://localhost:27017/nodetest1", {native_parser:true});

var routes = require('./routes/index');
var users = require('./routes/users');

var app = express();

//view engine setup
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'jade');

app.use(favicon());
app.use(logger('dev'));
app.use(bodyParser.json());
app.use(bodyParser.urlencoded());
app.use(cookieParser());
app.use(express.static(path.join(__dirname, 'public')));

//Make our db accessible to our router
app.use(function(req,res,next){
    req.db = db;
    next();
});

app.use('/', routes);
app.use('/users', users);

///Catch 404 and forward to error handler
app.use(function(req, res, next) {
    var err = new Error('Not Found');
    err.status = 404;
    next(err);
});

///error handlers

//development error handler
//will print stacktrace
if (app.get('env') === 'development') {
    app.use(function(err, req, res, next) {
        res.status(err.status || 500);
        res.render('error', {
            message: err.message,
            error: {}
        });
    });
}

//production error handler
//no stacktraces leaked to user
app.use(function(err, req, res, next) {
    res.status(err.status || 500);
    res.render('error', {
        message: err.message,
        error: {}
    });
});

module.exports = app;

Looks like you need to install the node modules. npm install -d should install all the dependencies.

Your bodyParser is wrong as well. It should be:

var bodyParser = require('body-parser')

see: body parser API
