node app command doesn't display anything

Question

I'm following this article to start using node.js. I got to the part where I should start my app with node app command. However, upon typing in the command and pressing enter, I just get a new input line.

C:\Users\Raketa\Desktop\workout-tracker>npm install -d
npm info it worked if it ends with ok
npm info using [email protected]
npm info using [email protected]
...
npm info ok

C:\Users\Raketa\Desktop\workout-tracker>node app

C:\Users\Raketa\Desktop\workout-tracker>

The article says I should get

Express server listening on port 3000 in development mode.

Edit:

Upon going to http://localhost:3000, it displays ERR_CONNECTION_REFUSED site saying

This site can’t be reached

Edit2:

app.js as requested:

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(path.join(__dirname, 'public', 'favicon.ico')));
app.use(logger('dev'));
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: false }));
app.use(cookieParser());
app.use(express.static(path.join(__dirname, 'public')));

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: 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: {}
  });
});


module.exports = app;

As it is, the app does not listen on any port - please see my suggested modifications to the app.js file:

Please add something like this at the end of the file (before module.exports = app; line):

var server = app.listen(3000, function() {
    log.info('Express server listening on port 3000');
});

Give it a try and let me know if it helps.
