How can I keep user sessions alive indefinitely?

Question

I have Nodejs, ReactJS and React Native app, MERN app is deployed on Heroku using free dynos. The session automatically times out after some time. I wish to maintain session forever without expiry.

I haven't set any expiry time, or MaxAge at the time of initialize session:

app.use(session({
  secret: 'thesecret',
  saveUninitialized: false,
  resave: false
}))

app.use(passport.initialize());
app.use(passport.session());

I expect to maintain session forever in my ReactJS and React Native app. How can I do that on Heroku?

Answer 1

By saving session in mongodb database we can maintain a continuous session in our nodeJS app.

var MongoDBStore = require('connect-mongodb-session')(session);
var store = new MongoDBStore({
uri: process.env.MONGODB_URI,
  collection: 'mySessions'
});

// Catch errors
store.on('error', function(error) {
  console.log(error);
});
app.use(session({
  secret: 'thesecret',
  saveUninitialized: false,
  resave: false,
  cookie: {expires: new Date(1586323351000),maxAge:31536000000},
  store: store,
}))
