NodeJs Socket.io房间

Question

This is a pretty simple question but i want to make sure that i am scaling our socket.io implementation correctly. We are using socket.io to respond back to the client after a lengthy process on the nodejs backend. So basically client makes call, then socket.io signals the client that the process has completed. Also socket.io ONLY responds to a temporary room that was established for the request.

In nodejs i created a global variable for the following so that i could emit back to the client room:

global.io = require('socket.io')(server);

But to create the room itself I am a little unsure how to create it globally such that only the socket that connected and made the request receives the response.

So if i have 500 client machines that initiate a connection through socket.io, each one will have its own socket. To ensure that the rooms are unique i use a guid across all 500. Of course i do not want all sockets to receive traffic if only one socket for a specific room is supposed to be evaluating the emit....

any ideas?

If I understood your question correctly, you're looking to send information to that 1 socket?

Perhaps something like this:

socket.broadcast.to(socketId).emit('someeventname', eventData);

If you have the connection open with that client, that means you have their socket id through socket.id . You can emit events to just that socket.
