This application has been implemented by without using STOMP using simple Spring Boot WebSocket API without harming the client flow of application.

• Each implementation / improvements are clearly mentioned in commit message in details.
• The goal of this app is to achieve the stuff without diving into lot more complexity and layered sub-protocols.
• This implementation does not require library like AJAX, STOMP.
• I have tried to achieve the greater result with the minimum changes in initial code.

Hope author will accept my work 🫡.
