How to iterate through a list of sockets at a specific namespace in a specific room?

[jasper-clarke]

Below here is code from the private messaging example.
It returns all the sockets and is iterable so I can get all the ID's and the username of users connected to the server PERIOD.

My problem is I need to be able to do the below but only for a specific room, being the one that the user is connected to. How can I do this?

    let users = [];
    for (let [id, socket] of io.of("/").sockets) {
      users.push({
        userID: id,
        username: socket.username,
        message: "",
      });
    }

You can use the fetchSockets() methods:

const sockets = await io.in("my-room").fetchSockets();
