Using Express + ws (websocket) libraries.

"App" uses some Express middleware to add the current user to the request object, but WS gets a Node request object without the information I need.

How can I pass this data to the websocket when upgrading connection?

const server = http.createServer(app); // app is using the express middleware to add info I need

const wss: WebSocket.Server = new WebSocketService(clients, { noServer: true }).wss;

server.on('upgrade', (request, socket: any, head) => {
    wss.handleUpgrade(request, socket, head, (ws: WebSocket) => {
        wss.emit('connection', ws, request);
    });
});

server.listen(3000, () => {
    console.log('Listening on port 3000');
});
