📖 Overview

This is the first stable release of the messaging system. The core focus was to establish a robust multidirectional communication flow and resolve critical identity management issues in multi-user environments.

📸 Technical Showcase

🌐 Multidirectional UI & UX

Visual distinction: Implementation of a dynamic color system for participants. This view proves the successful rendering of a group conversation where incoming and outgoing messages are clearly separated and identified.

🛡️ Authentication & Real-Time Sync

Client Interface	Session Storage (JWT Token Management)

Pro Tip: I chose sessionStorage over localStorage to ensure that sensitive authentication tokens are automatically cleared when the tab is closed, enhancing user security and preventing identity overlap in multi-tab environments.

Reliability: All core features are covered by unit and integration tests. This screenshot shows the green light on JWT-protected endpoint tests, ensuring that no message can be posted without a valid, authenticated session.
