rolling feature of express-session not supported

[semidark]

When setting the attribute rolling to true in express-session, the session.id cookie Max-Age in the Browser won't get updated/refreshed.

When most of the client/server communication is done via socket.io, the browser session will die, even if the client and server do communicate.

Demo Code for showcasing the bug / missing feature

Server js

"use strict";
let express = require("express");
let app = express();
let http = require("http").createServer(app);
let io = require("socket.io")(http);

function sendHeartbeat() {
  setTimeout(sendHeartbeat, 8000);
  io.sockets.emit("ping", { beat: 1 });
}
setTimeout(sendHeartbeat, 8000);

http.listen(3000, () => {
  console.log("Server is listening on http://localhost:3000");
});

let sess = require("express-session")({
  secret: "foobar",
  resave: true,
  rolling: true,
  saveUninitialized: true,
  cookie: {
    maxAge: 300000,
  },
});
app.use(sess);

let sharedsession = require("express-socket.io-session");
io.use(sharedsession(sess));

// app.use("/pong", function (req, res, next) {
//   res.json({ answer: "Workaround for session.id maxAge Bug" });
//   next();
// });

app.use(
  "/",
  express.static("public", {
    maxage: "0h",
  })
);

io.on("connection", (socket) => {
  socket.on("pong", (data) => {
    console.log("got pong from client");
  });
});

client javascript

"use strict";
let socket = io();

// async function getPong() {
//   const serverResponse = await fetch("http://localhost:3000/pong", {
//     method: "GET",
//     headers: {},
//   });
//   const response = await serverResponse.json();
//   console.log(response);
// }

document.addEventListener("DOMContentLoaded", () => {
  socket.on("ping", function (data) {
    console.log("recived Ping from server");
    //getPong();
    socket.emit("pong", { beat: 1 });
  });
});

As workaround implemented an simple fetch of an useless json. With that in place, the session.id gets refreshed. This are the commented code parts in the above example code.
