How to bind Socket.IO to express-sessions?

Question

Node.js

I can not combine sessions with Socket.io in any way. I log in through Passport.js and I need to remember this and work as with one client, but after every page update, the Socket works for me as with different users, I can’t combine it in any way.

Option 1. We write our own middleware that will fumble the session

var express = require("express");
var Server = require("http").Server;
var session = require("express-session");
var RedisStore = require("connect-redis")(session);

var app = express();
var server = Server(app);
var sio = require("socket.io")(server);

var sessionMiddleware = session({
    store: new RedisStore({}), 
    secret: "secret",
});

sio.use(function(socket, next) {
    sessionMiddleware(socket.request, socket.request.res, next);
});

app.use(sessionMiddleware);

app.get("/", function(req, res){
    req.session 
});

sio.sockets.on("connection", function(socket) {
  socket.request.session // Теперь сессия доступна через сокет
});


server.listen(8080);

Option 2. We use https://github.com/techpines/express.io
The option is working, but there are nuances with the express API. It is a bit outdated in places.
