#Implementation Details
- Front End is using StompJS over SockJS.
- There is a reconnect strategy when disconnects to the server are detected.
- Chat Controller is Using Springboot and Springboot starter for ampq (for Stomp).
- Chat Sessions are stored in a singleton service as an example of tracking users sessions and state.
- Chat messages are stored in a service as an example of a data store (it is just storage in this demo but could be use to give users messages if they re-connect).
- For getting existing chat messages a timestamp should be used to track client data sets 'state' in relation to servers available data.
