Socket.io - Server listen to specific room

as mentioned in Socket.io Doc about rooms - i know that the server can move sockets to a specific room and send an event to that specific room

transfer socket to a room :

io.on('connection', (socket)=>{
  socket.join('roomId');
});

emit event to sockets in that room :

io.to('roomId').emit('some event');

but i can't find a way that the server will listen to event coming only from a specific room, something like:

io.in('roomId').on('someevent',(socket)=>{....})

Socket.io has no function for this. You will have to listen for everyone on that event and check the socket's joined rooms array.
