WebSockets have compatibility with 96.5% of clients globally
OnConnection
method.OnOpen
gets called when a new connection is made.OnClose
gets called when a client quits. It's essential to keep an eye on memory management, and essential to keep tidying up as you move through the code.OnError
gets called when there is an exception faced by the user.OnMessage
gives the text of the JSON message, which is being exchanged with the client.
