A simple real-time notification app I built with Spring Boot and WebSockets. Basically, when someone sends a notification, everyone else connected sees it pop up instantly — no refreshing, no polling the server every few seconds. Same idea behind things like YouTube's notification bell or a "someone is typing..." indicator in chat apps.
Built with
- Java 17
- Spring Boot 3.3 (Web + WebSocket)
- HTML/CSS/JS
- Maven
