hope this fix your issue You can have your React app proxy to a route on your Express server, which will call req.isAuthenticated().
isAuthenticated() will return true/false depending on if the user is logged in.

Sharing a session store on Redis for a Django and a Express.js Application

Sharing a session store on Redis for a Django and a Express.js Application

I hope this helps you . You will have to write a custom session store for either Express or Django. Django, by default (as well as in django-redis-sessions) stores sessions as pickled Python objects. Express stores sessions as JSON strings. Express, with connect-redis, stores sessions under the key sess:sessionId in redis, while Django (not totally sure about this) seems to store them under the key sessionId. You might be able to use django-redis-sessions as a base, and override encode, decode, _get_session_key, _set_session_key and perhaps a few others. You would also have to make sure that cookies are stored and encrypted in the same way.
Obviously, it will be way harder to create a session store for Express that can pickle and unpickle Python objects.

To fix the issue you can do Use Redis for that. Fast and easy. If you plan on using Memcached (somehow easier) you might have problems with racing conditions, because memcached have no locking mechanism

will help you I am trying to get the laravel session id from the cookie on the header on nodejs. , Finally I got it too! Here's my solution. Works perfectly for me.
code :
// requirements
var PHPUnserialize = require('php-unserialize'); // npm install php-unserialize
var MCrypt = require('mcrypt').MCrypt; // npm install mcrypt


// helper function

function ord( string ) {    // Return ASCII value of character
    // 
    // +   original by: Kevin van Zonneveld (http://kevin.vanzonneveld.net)

    return string.charCodeAt(0);
}


function getSessionIdFromLaravelCookie() {

    var cookie = JSON.parse(new Buffer(req.cookies.laravel_session, 'base64'));
    var iv = new Buffer(cookie.iv, 'base64');
    var value = new Buffer(cookie.value, 'base64');
    var key = "_Encryption Key_";

    var rijCbc = new MCrypt('rijndael-256', 'cbc');
    rijCbc.open(key, iv); // it's very important to pass iv argument!

    var decrypted = rijCbc.decrypt(value).toString();


    var len = decrypted.length - 1;
    var pad = ord(decrypted.charAt(len));

    var sessionId = PHPUnserialize.unserialize(decrypted.substr(0, decrypted.length - pad));

    return sessionId;

}
Sharing session between socket.io and express not working on remote server

To fix this issue Making my comment into an answer since it appears to have solved your issue:
You need to make sure the address in the URL bar of the browser is EXACTLY the same host/port like http://ip.ad.dr.ess:80? If not, then socket.io and the web page won't share cookies and thus you would miss the session cookie.
Sharing Express Session Across Sub Domains

Sharing Express Session Across Sub Domains

seems to work fine This is possibly due to cookie being set at subdomain level. The session cookie for app.domain.com (app) is not valid for www.domain.com (WEB).
Try changing code to set cookie at domain level and see if this works.
code :
app.use(
    session({
        resave: true,
        saveUninitialized: true,
        secret: process.env.SESSION_SECRET,
        cookie: { maxAge: 1209600000, domain:'.domain.com' }, 
        store: new MongoStore({
            mongooseConnection: mongoose.connection,
            autoReconnect: true
        })
    })
);
