Alternative Run setup

Alternatively you can start this up with a Rabbit MQ as the Stomp Relay Message broker by setting the destination.stomp.simplebroker=false and configuring the rabbitmq broker details.

Using the App

• Browse to http://localhost:8080 to open the chat sample.
• Type in a name to be your username.
• Click the Connect button.
• Browse to http://localhost:8080/send_test in a separate window and you'll see a chat message appear in your chat sample application.

You can also open http://localhost:8080 in multiple browsers and send messages directly.

#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.

A note for production implementations DONT use the simple broker
