Reconnect and messages sent to the client while disconnected

[Clonex]

Hello,
We are considering switching our game server to use Socket.IO.
But I cant seem to find any documentation about how the reconnect works in practice.

My question is, does the library queue up messages sent from the server to a disconnected client.
So it can re-emmit them when the client is reconnected? Or will we have to implement that ourselves?

No, there is currently no buffer on the server.

Reference: https://socket.io/docs/v4/delivery-guarantees

There are ongoing discussions about adding that feature though: #4510

I see, thanks for clearing it up!
