WebSocket request-response subprotocol

Question

WebSocket provides a bi-directional communication like a human being talks. The client can send data to the server and the server can send data to the client anytime. But wh

Answer 1

(send a id with the request and wait for a reponse with the same id until a timeout period)

I created a lib that does exactly that, called WebSocketR2 (where R2 means Request Response): https://github.com/ModernEdgeSoftware/WebSocketR2

It also handles reconnecting to the server if a connection is lost, which could be helpful if you are doing web sockets through a load balancer.

The final result is you can implement callbacks on the web socket send function like this:

var request = {
    action: "login",
    params: {
        username: "test",
        password: "password"
    }
};

ws.send(request, function(response){
    console.log(response)
});
