NodeJS + Express: share session across multiple routes

I have an Express web application with some routes. The routes need to share the session when the web app interacts with users. The routes are declared in separate js files from the app.js.
In my app.js
var createError = require('http-errors');
var express = require('express');
var parseurl = require('parseurl')
var session = require('express-session')
var path = require('path');
var cookieParser = require('cookie-parser');
var logger = require('morgan');
var p_conf = require('./parse_config');
// Declare routes here
var indexRouter = require('./routes/index'); // index route
var usersRouter = require('./routes/users'); // user route
var itemRouter = require('./routes/items'); // item route
var app = express();
app.use(logger('dev'));
app.use(express.json());
app.use(express.urlencoded({ extended: false }));
app.use(cookieParser());
app.use(express.static(path.join(__dirname, 'public')));
// set up express-session
var sessionMiddleware = session({
secret: 'keyboard cat',
resave: true,
saveUninitialized: true
});
app.use('/', indexRouter);
app.use('/users', usersRouter);
app.use('/items', itemRouter);
// Assign an object to the session
app.use(function (req, res, next) {
req.session.test = "test";
next();
});
module.exports = app;
In my item.js for the item route:
const path = require('path');
const express = require('express');
const fetch = require('node-fetch');
const router = express.Router();
const p_conf = require('../parse_config');
const db_item = require('../db/db_item');
/* GET route root page. */
router.get('/', function(req, res, next) {
// Get the object in the session
console.log(req.session.test);
db_item.getItems()
.then(function(result) {
if (typeof result === "object")
return res.send(result["results"]);
else
return res.send(JSON.stringify({ "Error": String(result) }));
})
.catch((err) => {
return next(err);
})
});
module.exports = router;
In the app.js the session is created and assigned with a test object when the web app is initialised. The item route is supposed to get the same session and retrieve the test object. However, req.session.test is always undefined when the route root is accessed.
How can the item and user routes access the session and share the session scoped objects across?

Try changing the order of declaring routes and session in app.js. Also, need to use sessionMiddlware (app.use) before using session.
var sessionMiddleware = session({
secret: 'keyboard cat',
resave: true,
saveUninitialized: true
});
app.use(sessionMiddleware);
app.use(function (req, res, next) {
req.session.test = "test";
next();
});
app.use('/', indexRouter);
app.use('/users', usersRouter);
app.use('/items', itemRouter);

Cannot GET with nodejs?

I have a simple nodejs app with some users. I want to load a specific user profile using a URL localhost/users/(username) but I'm getting this error when I try to load the URL:
Cannot GET /users/test
Here's my user.js routes file for the user page:
var express = require('express');
var router = express.Router();
var User = require('../models/user');
// GET user by username
router.get('/users/:username', function(req, res) {
var username = req.params.username;
res.send(req.params);
res.render('user');
});
module.exports = router;
I have a user.handlebars file in my views folder so it should load the file. What am I missing in my routes file? Any help would be greatly appreciated. Thanks!!

Render function renders a view and sends the rendered HTML string to the client.Take a look at documentation.
But what you are trying to archive is to send data first and then render and send again. So, just delete the line with send.
router.get('/users/:username', function(req, res) {
var username = req.params.username;
res.render('user');
});
And, please, edit your question by adding your code with middleware and add your error.
Update
Take a look at the way how you define your routes for users.
You have to remove /users from defining route in users.js file

Error: Missing Helper: "iff"

For some reason, I keep getting this error every time i try to use {{#iff}
Is this not rendering my page as handlebars? Did I use the {{#iff}} statement correctly?
My console prints this out:
Failed to load resource: the server responded with a status of 500 (Internal Server Error)
This is my handlebars(login.hbs):
<h1><span class="fa fa-sign-in"></span> Login</h1>
{{#iff message.length '>' 0}}

link to server.js
I've seen something similar to :
app.use(express.static(__dirname + '/public/views/'));
But I don't really understand why is not working
Hope you can help me guys !

In express.js order of middleware declaration is very important. You must define express.static middleware earlier than any of the routes:
SERVER.JS:
.. require
// logger must be defined first if you want log all the requests
app.use(morgan('dev'));
// after that you should define express.static middleware
app.use(express.static(__dirname + '/public/'));
app.set('views', __dirname + '/public/views');
app.set('view engine', 'jade');
// cookie and body parser must be defined before passport and session middleware
app.use(cookieParser());
app.use(bodyParser());
app.use(session({ secret: 'vintageisthelaw' }));
app.use(passport.initialize());
app.use(passport.session());
app.use(flash());
// your routes must be defined in the end
app.use('/', routes);
app.use('/admin', adminRoutes);
app.listen(port);
console.log('The magic happens on :\n\n http://localhost:'+ port+'\n\n');
