Socket.IO - how to emit event to everybody in the room, including sender?

问题:

io.emit('chat message', msg); 

Now I added rooms and try to do the same thing using

socket.broadcast.to(socket.room).emit('chat message', msg); 

or

socket.to(socket.room).emit('chat message', msg); 

but both only send the message to receivers, but not to the sender.

What should I do so that this message also goes to the sender, who's in the chat room as well?

Thanks!

Found an answer in this question: Socket.io Won't Emit messages to rooms on discconect

simply use

io.sockets.in(socket.room).emit('chat message', msg);
