router.get function not being called

I am using passport.js for a basic log in/log out system. For some reason, the router.get('/signout', function(req, res)) is not being called when I run http://localhost:3000/auth/signout on Advanced rest client. Instead I am getting a Internal Server Error: 500. Login works just fine, but signout does not. Here is my app.js and authenticate.js:
App.js
var express = require('express');
var path = require('path');
var favicon = require('serve-favicon');
var logger = require('morgan');
var passport = require('passport');
var session = require('express-session');
var cookieParser = require('cookie-parser');
var bodyParser = require('body-parser');
//Initialize models
require('./models/models.js');
var api = require('./routes/api');
var authenticate = require('./routes/authenticate')(passport);
var mongoose = require('mongoose');
//connect to mongodb
mongoose.connect("mongodb://localhost:27017/chirp-test");
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(path.join(__dirname, 'public', 'favicon.ico')));
app.use(logger('dev'));
app.use(session({
secret: 'super duper secret'
}));
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: false }));
app.use(cookieParser());
app.use(express.static(path.join(__dirname, 'public')));
app.use(passport.initialize());
app.use(passport.session()); //This creates a unique has for our session
//Initialize Passport
var initPassport = require('./passport-init');
initPassport(passport);
app.use('/auth', authenticate);
app.use('/api', api);
// 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 handler
app.use(function(err, req, res, next) {
// set locals, only providing error in development
res.locals.message = err.message;
res.locals.error = req.app.get('env') === 'development' ? err : {};
// render the error page
res.status(err.status || 500);
res.render('error');
});
module.exports = app;
Authenticate.js
var express = require('express');
var router = express.Router();
module.exports = function(passport){
//sends successful login state back to angular
router.post('/success', function(req, res){
console.log('successful');
res.send({state: 'success', user: req.user ? req.user : null});
});
//sends failure login state back to angular
router.get('/failure', function(req, res){
res.send({state: 'failure', user: null, message: "Invalid username or password"});
});
//log in
router.post('/login', passport.authenticate('login', { failureRedirect: '/auth/failure' }),
function(req, res) {
//res.redirect('/auth/success');
res.send({state: 'success', user: req.user ? req.user : null});
});
//sign up
router.post('/signup', passport.authenticate('signup', {
successRedirect: '/auth/success',
failureRedirect: '/auth/failure'
}));
//log out
router.get('/signout', function(req, res) {
console.log('Signing out...');
req.logout();
res.redirect('/');
});
return router;
}

You have registered nothing under "/". So when "auth/logout" call redirect to redirect("/"), I guess client is redirected but goes into your "error handler" which sends a 500 error...

Undefined while sending post nodejs

I try to send a form with data in my nodejs app but I get "undefined" I am not sure does it matter but in console first I see "undefined", then POST. I have tried some "fixes" from the Internet like adding "type:'application/*+json', inflate: false" to app.use(bodyParser.json...) but nothing worked for me...
Undefined
POST /users/register 200 32.777 ms - 2346
this is my routes/users.js file:
var express = require('express');
var router = express.Router();
router.get('/register', function(req, res, next) {
res.render('register', {
'title': 'Register'
});
});
router.post('/register', function(req, res, next) {
console.log(req.body.name);
});
module.exports = router;
heres my jade file
form(method='post', action='/users/register', role='form')
.form-group
label Name
input.form-control(type='text', name='name', placeholder='Enter Name')
input.btn.btn-default(name='submit', type='submit', value='Register')
and app.js
var express = require('express');
var path = require('path');
var favicon = require('serve-favicon');
var logger = require('morgan');
var expressValidator = require('express-validator');
var cookieParser = require('cookie-parser');
var session = require('express-session');
var passport = require('passport');
var LocalStrategy = require('passport-local').Strategy;
var bodyParser = require('body-parser');
var flash = require('connect-flash');
var mongo = require('mongodb');
var mongoose = require('mongoose');
var db = mongoose.connection;
var routes = require('./routes/index');
var users = require('./routes/users');
var app = express();
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'jade');
app.use(logger('dev'));
app.use(bodyParser.json({ type: 'application/*+json' }));
app.use(session({
secret: 'secret',
saveUninitialized: true,
resave: true
}));
app.use(passport.initialize());
app.use(passport.session());
app.use(expressValidator({
errorFormatter: function(param, msg, value) {
var namespace = param.split('.'),
root = namespace.shift(),
formParam = root;
while(namespace.length) {
formParam += '[' + namespace.shift() + ']';
}
return {
param: formParam,
msg: msg,
value: value
};
}
}));
app.use(cookieParser());
app.use(express.static(path.join(__dirname, 'public')));
app.use(flash());
app.use(function(req, res, next) {
res.locals.messages = require('express-messages')(req, res);
next();
});
app.use('/', routes);
app.use('/users', users);
app.use(function(req, res, next) {
var err = new Error('Not Found');
err.status = 404;
next(err);
});
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
});
});
}
app.use(function(err, req, res, next) {
res.status(err.status || 500);
res.render('error', {
message: err.message,
error: {}
});
});
module.exports = app;
Routing works fine what show setting up a title to "Register", but I have problems with sending post :/

You're configuring body-parser to only accept JSON request bodies, but your form is submitted in URL-encoded format (application/x-www-form-urlencoded).
For that, you need to add the correct parser:
app.use(bodyParser.urlencoded({ extended : true }));
More information, also on the meaning of extended : true, here.

404 Not Found when use nodejs to localhost

I made a simple login system using node and express 4.x. But I write localhost:3000 and see "Not Found 404".I think the problem is the epxress viersion is 4.x,however some code is express 3.x.
This is the error page :
Not Found

In your app.js you are loading the routes but you are not telling express to use it. Put app.use('/', routes); right before the 404 catch.
PS: It's the line you've got commented.

Why is my server returning error 500 while trying to set a cookie?

I have an express v4 server with a route called admin. When the user post a password to the admin route, I want to respond by setting a cookie on the user's browser and sending a small json. For some reason, the server keeps returning error 500 when trying to respond. I'm assuming that this is something to do with the cookie as I can do "res.send()" without any problem. I'm new to express/nodejs so any help is appreciated.
admin.js
var express = require('express');
var router = express.Router();
var cookieParser = require('cookie-parser');
/* POST HANDLER */
router.post('/', function(req, res) {
var on = {'admin' : "on"};
res.cookie(cookie , 'cookie_on').send(on);
});
module.exports = router;
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 admin = require('./routes/admin');
var blogposts = require('./routes/blogposts');
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('/admin', admin);
app.use('/blogposts', blogposts);
// 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', {

Dumb mistake: Cookie should have been 'cookie'...
