How do I share sessions with express and websockets using connect-sqlite3?

[Eric Twose]

I need to share sessions between express-session (v4) GET requests and WebSockets on('connection') using connect-sqlite3.

The following basic setup without sqlite3 (from Azmisov's answer at https://stackoverflow.com/questions/12182651/expressjs-websocket-session-sharing) works:

global.app = express();
var sessionParser = require('express-session')({
    secret:"some secret",
    resave: true,
    saveUninitialized: true
});
app.use(sessionParser);

app.get('*', function (req, res) {
	req.session.working = "Yes";
});

wss.on('connection', function connection(ws, req) {
	sessionParser(req, {}, function(){
		console.log("New websocket connection: Working = " + req.session.working + ".");
	});
});

However, when I try to implement this with connect-sqlite3:

var sessionParser = require('express-session');
var SQLiteStore = require('connect-sqlite3')(sessionParser);
app.use(sessionParser({
	store: new SQLiteStore({dir:configuration.data_dir, db:'sessions.s3db', table:'sessions',}),
	secret: 'some secret',
	resave: false,
	saveUninitialized: true,
	cookie: {
		maxAge: configuration.session_cookie_maxage_ms,
		name: 'shadowlands'
	}
}));

app.get('*', function (req, res) {
	req.session.working = "Yes";
});

wss.on('connection', function connection(ws, req) {
	sessionParser(req, {}, function(){
		console.log("New websocket connection: Working = " + req.session.working + ".");
	});
});

In wss on('connection') at sessionParser(req, {}, function(){ ...), I get:

express-session deprecated undefined resave option; provide resave option; provide resave option.
express-session deprecated undefined resave option; provide saveUninitialized option; provide saveUninitialized option.
express-session deprecated req.secret; provide secret option.

This error still occurs if I change to:

sessionParser(req, {secret: 'some secret', resave: false, saveUninitialized: true}, function(){

The error goes away if I take out "req":

sessionParser({secret: 'some secret', resave: false, saveUninitialized: true}, function(){

But then the sessionParser function does not get called, and req.session.working is not shown in the console.

Any help or an example in the readme much appreciated, thanks!

I managed to fix it using cookie-parser and cookie in the websocket on('connection').
