let socket = SocketIOClient.init(socketURL: URL(string: "https://ts4.steelsea.net:8080")!, config: [.log(true), .forcePolling(true),.secure(true),.selfSigned(true)])

        socket.on("connect") {data, ack in
            print("socket connected")
        }

        socket.on("currentAmount") {data, ack in
            if let cur = data[0] as? Double {
                socket.emitWithAck("canUpdate", cur).timingOut(after: 0) {data in
                    socket.emit("update", ["amount": cur + 2.50])
                }

                ack.with("Got your currentAmount", "dude")
            }
        }

        socket.connect()
