Passing an object into a pug/jade template with express

The basic problem is as follows:
Passing an object from my c# program, which is serialize and send through a socket. Achieved this in node.js/express application with socket.io.
Need to pass this to the client and using pug as the template engine.
Everything tried so far just doesn't seem to be working. Can't access the elements in the object. Pretty new to node and express so please bear with me.
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('./app_server/routes/index');
var users = require('./app_server/routes/users');
var app = express();
var app = require('express')();
var server = require('http').Server(app);
var io = require('socket.io')(server);
server.listen(80);
// view engine setup
app.set('views', path.join(__dirname, 'app_server', '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({ extended: false }));
app.use(cookieParser());
app.use(express.static(path.join(__dirname, 'public')));
app.use('/', routes);
app.use('/users', users);
io.on('connection', function (socket) {
socket.emit('news', { hello: 'world' });
socket.on('my other event', function (data) {
console.log(data);
});
});
// 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;

//THIS IS WHERE I DON'T KNOW HOW TO ACCESS THE OBJECT AND ITS PROPERTIES
Can see the object in the console so the data is appearing.
Tried many different variations, but nothing seems to be working. Any input or guidance would be welcome.
Thanks in advance.

Express Error: TypeError: Router.use() requires middleware function but got a Object

I am creating an upload/download app, i don't know why its only my app.js file is having this problem. I searched all other answers on the internet but still it did not solve the problem.
here is the code below:
var express = require('express');
var path = require('path'); // add path to set and get
var fs = require('fs'); // add filesystem
var connect = require('connect');
var favicon = require('serve-favicon');
var logger = require('morgan');
var cookieParser = require('cookie-parser');
var bodyParser = require('body-parser');
var connect = require('connect');
var http = require('http');
var routes = require('./routes/index');
var users = require('./routes/users');
//var upload = require('./routes/upload');
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')));

Thanks for your help.

check in your all files
make sure you don't miss export it
module.exports = router;

Router.use() at all times requires a Middleware function as an argument. Assuming your route to download some files from your server, it should Look similar to this.
var Router = express.Router();
function downloadFiles(request,response) {
// some code to dowload files
}
// The above function which takes request and response
// should be passed to Router.use()
Router.use(downloadFiles);
When you that error it means that what you passed to Router.use() is not a middleware function like downloadFiles.

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', {
message: err.message,
error: {}
});
});
module.exports = app;

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

How to properly apply routes inside another file

I'm fairly new to express js and I want to know how to use router. I created a file named categories.js inside routes directory with this code.
categories.js code:
var express = require('express');
var router = express.Router();
/* GET users listing. */
router.get('/categories', function(req, res) {
res.send('this is the category');
});
module.exports = router;
inside the app.js i have this code:
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 categories = require('./routes/categories');
var app = express();
var mongoose = require('mongoose');
mongoose.connect('mongodb://localhost/test');
// view engine setup
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'hjs');
// 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);
app.use('/categories', categories);
// 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;
I have tried understand what is wrong but i can't see to figure out. thanks in advance.
This is the error im getting
Not Found
404
I will like to add inside the routes directory i have a index.js file and this one works.
var express = require('express');
var router = express.Router();
/* GET home page. */
router.get('/', function(req, res, next) {
res.render('index', { title: 'Express' });
});
module.exports = router;
I think my application is not reading the categories.js file, because when I put the category.js code inside index.js it works. but it doesn't work if i put it in a separate file in my case category.js.

I think you've got your categories route hooked up wrong, your categories are mapped to /categories/categories in your code. To fix it, try this in your app.js:
app.use('/', categories);
If you don't want to prefix, you can also simply do this:
app.use(categories);

express router not found

I created an express project using the express generator like following
express project_name
and
npm install
This is my 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({ 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;
These are my routes
var express = require('express');
var router = express.Router();
/* GET home page. */
router.get('/', function(req, res, next) {
res.render('index', { title: 'iDanG Management' });
});
module.exports = router;
I have following index.jade
extends layout
block content
div.container
div.row
form(id='myform' action='' method='post')
p Name:
input(type='text' name='name')
p E-Mail:
input(type='text' name='email')
input(type='submit' value='add')
table(class='table table-hover' id='user_table')
thead
tr
th Name
th Email
tbody
script.
$(document).ready(
function() {
$('#user_table').dataTable({
"pagingType": "simple_numbers",
"ordering": false
});
$('#myform').ajaxForm({ beforeSubmit:
function (formData, jqForm, options) {
$('#table').DataTable().row.add([formData[0].value, formData[1].value]).draw();
return false;
}
});
});
And following layout.jade
doctype html

link(rel="stylesheet" href="//maxcdn.bootstrapcdn.com/bootstrap/3.3.2/css/bootstrap.min.css")
link(rel="stylesheet" href="/javascripts/jquery.dataTables.min.css")
body
block content
when I try to submit that form I receive following error:

For the forms I used this
Do you have any suggestions how I can solve this problem? Help is highly appreciated!

It seems like you are doing a post request and your routes does not have post handler.
May be add route for post:
router.post('/', function(req, res, next) {
//do something and return data here?
});
