Good day guys here is my code :

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

var app = express();
app.set('trust proxy', 1);

app.use(session({
secret: 'secret',
saveUninitialized: true,
resave: false,
maxAge: 1000 * 60 * 15,
cookie:{
    secure: true
       }
}));

this code always returns on my log a :

Warning: connect.session() MemoryStore is not designed for a production environment, as it will leak memory, and will not scale past a single process.

i tried googling about it but i don't seems to understand some tutorials . Sorry for my bad english.

Using cookie-session instead of express-session solved this issue for me.

You store the session on the client and not on the server with cookies.

Simply:

  1. Install it with npm install cookie-session
  2. Change

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

    to var session = require('cookie-session');

It's all about storing sessions, you should add a storing system that store sessions into your database. This help your app to manage sessions.

For example, in mongodb you can use connect-mongo, you should found a store package and for other databases.

https://www.npmjs.com/package/connect-mongo

const session = require('express-session');
const MongoStore = require('connect-mongo')(session);

app.use(session({
    secret: 'foo',
    store: new MongoStore(options)
}));
