PHP session variable equivalent for the mean stack

Question

When I first started learning PHP, you could use $_SESSION array to store information and use it on multiple sites, like setting a username of someone who has logged in.

Is there something like that for the MEAN stack?

Module to use express-session

var express = require('express');
var session = require('express-session');
var app = express();

initialize

app.use(session({secret: 'something'}));

sessionVariable in the below code is equivalent to $_SESSION in php.

  var sessionVariable;
    app.get('/',function(req,res){
    sessionVariable=req.session;

    sessionVariable.email = 'test@test.com;
    sessionVariable.username = 'test'; 
    });
