express-socket.io-session

is a ready-made solution for your problem. Normally the session created at socket.io end has different sid than the ones created in express.js

Before knowing that fact, when I was working through it to find the solution, I found something a bit weird. The sessions created from express.js instance were accessible at the socket.io end, but the same was not possible for the opposite. And soon I came to know that I have to work my way through managing sid to resolve that problem. But, there was already a package written to tackle such issue. It's well documented and gets the job done. Hope it helps
