How to implement connection resumption in socket.io?

Question

Node.js

In online games such as agar.io, when the internet connection is cut off and then resumed within a short period of time, the client continues from the same place where he left off. On the server, I am using socket.io.
io.on("connection",function (socket) {
console.log("Player "+socket.id+" connected");
});
The problem is that when reconnecting, the server creates another connection with a new socket and id. The question is how to find out that the same client is connected that disconnected a couple of seconds ago? I thought to store on the client the id of the first connection, which is transferred to the server. Is this the normal approach? Maybe you can resume the session automatically?
