## Core Components Overview

### Authentication & Security

The Auth Module provides a comprehensive JWT-based authentication system with WebSocket support, refresh tokens, and integration with external auth services.

### Real-time Communication

The WebSocket Module delivers secure real-time communication with JWT authentication, role-based channel authorization, and fine-grained permission control.

### Data Management

The Data Transfer Module offers flexible data export/import capabilities with support for multiple formats, encryption, and various storage options.

### Messaging & Events

The Messaging Services facilitate event-driven architecture with support for both in-memory and distributed message brokers.
