Maintain sessions in Node.js

Question

How can I maintain my SESSIONS in Node.js?

For example, I want to store UserID in SESSION using Node.js. How can I do that in Node.js? And can I use that Node.js SESSION in PHP too?

I want the following in Node.js:

<?php $_SESSION['user'] = $userId; ?>

Answer 1

First install the session package

npm install express-session --save

Initialization of the session on your server page

var express = require('express');

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

var app     = express();

app.use(session({secret: 'ssshhhhh', saveUninitialized: true, resave: true}));

Store session

sess = req.session;

var user_id = 1;

sess.user_id = user_id;

Access the session

sess = req.session;

sess.user_id

Answer 2

Let me divide your question in two parts.

1. How can I maintain my SESSIONS in Node.js?
   Answer: Use express-session middleware for maintaining SESSIONS
2. Can I use that a Node.js SESSION in PHP too?
   Answer: Yes, you can use that session in PHP too, but keep in mind you have to store that session in the database.
