No, it's not currently possible, but it shouldn't be that hard to implement. Could you please explain your use case?

EDIT: it's now available, see below

This was implemented in 7de2e87 and included in socket.io@4.0.0.

Example:

io.except("room1").emit(/* ... */); // to all clients except the ones in "room1"
io.to("room2").except("room3").emit(/* ... */); // to all clients in "room2" except the ones in "room3"

socket.broadcast.except("room1").emit(/* ... */); // to all clients except the ones in "room1" and the sender
socket.except("room1").emit(/* ... */); // same as above
socket.to("room4").except("room5").emit(/* ... */); // to all clients in "room4" except the ones in "room5" and the sender

@darrachequesne

Hey, do you have any ideas on how to implement this? I have a use case for this, and would like to hear your thoughts.

@pluiz-briteris this has been implemented in version 4.0.0, please see my answer above.

I may be mistaken, but isn't that for excluding a room? The original question says excluding a particular socket by id.

E.g. I use the underlying server to emit but exclude a given socket of a given room, by this socket id.

Or is this happening somehow in one of the examples you shared?
