On the client side, I am expecting json? And I do not have a
clientSocket.on?
What I have is:
ws.onmessage = function(message) {
var parsedMessage = JSON.parse(message.data);
console.info('Received message: ' + message.data);
switch (parsedMessage.id) {
There a few different "case" situations like 'Stop', 'Default', etc.
