404 with simple Express routing

I am trying to set up routing in my Node.js app using Express.js and Mongoose.js using this tutorial - Learn to Build Modern Web Apps with MEAN

When I test with cURL, it gives me this message:

(the curl script is: curl --data 'title=test&link=http://test.com' http://localhost:3000/#/posts)

Error: Not Found

    at router (/Users/adamz/flapper-news3/node_modules/express/lib/router/index.

For reference my app.js file is as follows:

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 mongoose = require('mongoose');

require('./models/Posts');
require('./models/Comments');

mongoose.connect('mongodb://localhost/news');


var app = express();

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

// 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({ 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;

And my routes/Index.js is:

var express = require('express');
var router = express.Router();

var mongoose = require('mongoose');
var Post = mongoose.model('Post');
var Comment = mongoose.model('Comment');


/* GET home page. */
router.get('/', function(req, res, next) {
  res.render('index', { title: 'Express' });
});

router.get('/posts', function(req, res, next) {
  Post.find(function(err, posts){
    if(err){ return next(err); }

    res.json(posts);
  });
});


router.post('/posts', function(req, res, next) {
  var post = new Post(req.body);

  post.save(function(err, post){
    if(err){ return next(err); }

    res.json(post);
  });
});

module.exports = router;

Is something out of order? I copied and pasted directly from the tutorial, Node.js is running, mongodb is running, so I'm really not sure what's going on.

Let me know if any other info would help. Thanks in advance for your help.

You need to define mongoose before express:

var mongoose = require('mongoose');

require('./models/Posts');
require('./models/Comments');

mongoose.connect('mongodb://localhost/news');

var express = require('express');
var path = require('path');

I believe your curl script should include quotations around the site:

curl --data "title=test&link=http://test.com" "http://localhost:3000/posts"
