Hello everyone!
I need some help with express-session. It seems it doesn’t save cookies for routs.
I save cookies on the first route and try to use it on another route, but get undefined. I logged it to the console. It seems like that:
.
Here is my code at app.js:
var session = require('express-session');
const MongoStore = require('connect-mongo')(session);
const path = require('path');
var cookieParser = require('cookie-parser');
app.use(cookieParser());
app.use(session({
secret: 'keyboard cat',
resave:true,
resave: false,
saveUninitialized: true,
store: new MongoStore({
url: 'mongodb://localhost/dictionary'
})
}));
login.js:
else {
req.session.username = username;
console.log('cookie at login: ', req.session);
res.json(username);
//res.json(req.session.username)
}
home.js:
.get((req, res) => {
console.log('cookie at home: ', req.session);
//if (req.session.username) {
fs.readFile('../html/home.html', 'utf8', (err, data) => {
if (err) console.log(err);
res.write(data);
res.end();
});
What am I doing wrong? I can see the cookie in mongodb, how to use it for different routes?
Can you see the cookie in the browser?
Yes, I see it in the browser and in the mongodb
I noticed that I create 2 types of sessions the first is is without username for /index route and the second with username for /login route. And the app uses the first. How to fix it? A user get the index page first and the app creates a session without username and then uses it. Please help to understand how to fix it.
or I should create one page app? What to use with usual webpages then?
Can you provide a link to your github page so we can set up a dev environment to troubleshoot ?
Here is a link to bitbucket or it should be exactly github? https://bitbucket.org/ostefani/dictionary-app/src/master/
In order to start a server use index.js in the server folder.
Where are you setting the cookie?
Stock Overflow - Set a cookie in Node.JS
You can use res.cookie() in Express to set your cookies on the browser side.
Sorry @OStefani I’m traveling and won’t have access to my PC till next week and can’t fully troubleshoot.
"use strict"//primary module to interact with client
var express = require('express');
var cookieParser = require('cookie-parser');
var bodyParser = require('body-parser');
var axios = require('axios')
var queryString = require('query-string');
var mongoose = require('mongoose');
var session = require('express-session');
var MongoStore = require('connect-mongo')(session);
var app = express();
//not using session in this project but good to have incase
app.use(session(
{ secret: process.env.SESSION_SECRET,
store: new MongoStore({ mongooseConnection: mongoose.connection }),//warning in node if this option is not included
resave: true,
saveUninitialized: true
}
show original
The only difference maybe that I’m using mongoose , are your sessions being saved to the database? See if there is a collection called sessions for instance. If so then you can eliminate that issue.
If you don’t have it resolved by next week , I’ll take a closer look then. Also if you don’t need to save the session info in a db I recommend you take a look at the more light weight version of saving cookie info for a client called cookie-session, it doesn’t need a db and much easier to use , you just set the time expiry of the cookie and you are good to go. Best of luck

Dereje1 Thanks for your reply. Yes I am using mongodb for saving sessions. And after I do a request to index and then to home route I see two documents there. One is without username and one is with username. But the second session is not used. How to use it if it presents in db?
s_coder I am using express session middleware and mongodb
What do you get when you console.log req.session inside your index.js file in your terminal, for any route ?
Actually go to your home route herehttps://bitbucket.org/ostefani/dictionary-app/src/e926fd929cde68db650290aa0a375c461f2b7554/routes/home.js?at=master&fileviewer=file-view-default
And console.log req.session in the root route , is it defined ?
Dereje My root route is index. The user got to the index first, signin and then get home
The first session is used for /home route it ‘doesn’t know’ about the username
Could you post the result you get when you do console.log(req.session) In the route I asked you for earlier ?
I’ve post a screenshot, do you see it?
Let me copy and past that text here, maybe you didn’t get the screenshot
Server running at http://127.0.0.1:3000
Get request to index: Session {
cookie:
{ path: '/',
_expires: null,
originalMaxAge: null,
httpOnly: true } }
Post reques to index: Session {
cookie:
{ path: '/',
_expires: null,
originalMaxAge: null,
httpOnly: true },
username: 'test1' }
Get request to home: Session {
cookie:
{ path: '/',
_expires: null,
originalMaxAge: null,
httpOnly: true } }
Also I’ve consoled log sessions from the index.js which is in the server folder
Server running at http://127.0.0.1:3000
From index file Session {
cookie:
{ path: '/',
_expires: null,
originalMaxAge: null,
httpOnly: true } }
From index file Session {
cookie:
{ path: '/',
_expires: null,
originalMaxAge: null,
httpOnly: true } }
From index file Session {
cookie:
{ path: '/',
_expires: null,
originalMaxAge: null,
httpOnly: true } }
There isn’t any username at all
Ok , what do you get for req.session when the user is not logged in for the same route?
Ok, try instead of this
req.session.username = username;
Use this
req.session.cookie.username = username;
Does that fix your issue?
