Socket.IO - how to emit event to everybody in the

问题:

In my Socket.Io / Node.Js / Express app - before I added chat room – I used to emit events like this for everyone (including the sender):

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);
