epressjs/node.js npm start issue about generator HOT 4 CLOSED

It's no problem. So continuing, the reason is because you are not using some of those libraries correctly. For instance, that message is because app.use(bodyParser.urlencoded()) needs to be app.use(bodyParser.urlencoded({ extended: true })) according to that module's documentation.

@dougwilson ok I added that along with bodyParser.json & sookieParser. I'm not sure if that's what you meant to do, so I've been reading the API documentation but now its thowing
TypeError: undefined is not a function
Accompanied with the same locations. I feel like I'm missing something big here, and I don't want to make you walk me through this step by step. But if you have another idea based off of that or where I showed look to move this forward; like a good starting point for a decent java/web dev but with just starting with cmd, would be great. I'll give you a break after this next suggestion because I have a paper I need to writ. This code style is just addicting once you get started with it!

Hi, sorry, @ADC5 , do you still need help? If so, can you post the corresponding source as well as the error with it's full stack trace?

Hi Christopher,
Thanks for responding to me!  The issue that I'm having is that I can't get my app to connect to my mongo db.  I'm going to paste each of my pages in this:
app.js:

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

// uncomment after placing your favicon in /public
//app.use(favicon(__dirname + '/public/favicon.ico'));
app.use(logger('dev'));
app.use(bodyParser.json());
app.use(bodyParser.urlencoded());
app.use(cookieParser());
app.use(express.static(path.join(__dirname, 'public')));
app.use('/', routes);
app.use('/users', users);
/// catch 404 and forwarding 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: err
        });
    });
}
// 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: {}

As you can see, we're using a global variable and definingour functions at the top level. This is actually not a greatidea and I'm only doing it for speed and simplicity. In a real app, you want to define a single master global, which you canthen populate with properties, methods, etc … as needed, thus helping to avoid conflicts or generally pollute the namespace. If you want to learn more about this strategy, I strongly recommendpicking up a copy of "JavaScript: The Good Part"

This how I've been trying to connect my db (after mkdir data, path: c:\node\nodetest3\data ->
'mongod --dbpath c:\node\nodetest3\data'
I have  the mongo.exe files save in c:\mongo\ and the app files save in  "c:\node\nodetest3", the data file is created in here and I followed the directions for creating the database and am able to retrieve the data just fine but it's not posting to the page when I enter 'loaclhost:3000' into my browser.  It shows everything else perfectly though, so I'm assuming (could be wrong as an amateur to be making this assumption) that this is the issue.  back to the issue, so I can start the app with 'npm start' and see it perfectly.I've tried opening the mongo shell then: c:\mongo> mongoMongoDB shell version 3.0.3>use nodetst3switched d to nodetest3'fullname>db.userlist.insert({'username' : 'alex','email' :[email protected]','fullname' : 'alex carl','age' : '26','location' : 'Seattle','gender' : 'male'})WriteResults({ "nInserted" : 1 })>
I don't remember the call off the top of my head ,but when I then search the db using anyone of these vatibles and it's value, it returns the whole user summary.  I'm so close that I can taste t and would greatly appreciate if you can help get this connected.  Ultimately I want to try to use this to try and create an app for the DCenter (disability rights center) at my college (UW Seattle).  I really love to program and I somehow came across this page and am so thankful for that fact, because I love learning/using all the aspects of node.js.  Ok, now I'll add the error messages, but I'm not sure if it's actually throwing any, because it is running, just doesn't have any of the data included on the page.
