send data to specific client server-end

[cherimo]

I can't find any clear information on the internet what the comparable function should be of the following code:

socket.to(socketClient).emit("eventName", "Message", function(res) {
   console.log("Respont: ",res);
})

I really need something like this where I can send Data to the Server-side of the client instead of the Client-side.

Here https://newbedev.com/socket-io-emit-to-socket-id-code-example they indicate the following text:

// WARNING: socket.to(socket.id).emit() will NOT work, as it will send to everyone in the room named socket.id but the sender. Please use the classic socket.emit() instead.

Is there any alternative to this?

Hi! You can use the serverSideEmit functionality for this use case: https://socket.io/docs/v4/server-instance/#serversideemit
