I have tried this link: Socket.IO subscribe to multiple channels.
I have used method socket.on and io.emit for request and response respectively.
Currently I have facing issue that I got response to all users.
I want to just notify for particular user.
When a user connects, it should send a message to the server with a username which has to be unique.
A pair of username and socket should be stored in an object like this:
var users = {
'[email protected]': [socket object], // USER SOCKET OBJECT
'[email protected]': [socket object], // USER SOCKET OBJECT
'[email protected]': [socket object] // USER SOCKET OBJECT
}
On the client, emit an object to the server with the following data:
{
to:[receiver's username],
from:[the person who sent the message],
message:[the message to be sent],
//..other details..
}
On the server, listen for messages. When a message is received, emit the data to the receiver.
users[data.to].emit('new-message', data.message)
On the client, you will need to listen to new-message.
