Tell me about the chat in your project — what features were there? How was the work of the front-end and back-end organized?

The chat project implemented features for real-time message exchange, support for group and private chats, as well as displaying user status (online/offline). WebSocket was used on the frontend for a persistent connection to the server, ensuring instant message delivery.

The frontend and backend work was organized as follows:

• The frontend opened a WebSocket connection and listened for new message events, status updates, and other notifications.
• When sending a message, the frontend sent data via WebSocket to the server.
• The server processed messages, stored them in the database, and distributed them to other chat participants via WebSocket.

A reconnection logic was also implemented for connection loss, along with message history pagination through REST API.

This approach allowed for a responsive interface and real-time data relevance.
