Broadcast server

This project demonstrates a simple broadcast server that will allow clients to connect to it, send messages that will be broadcasted to all connected clients.

---

Overview

The system consists of two main components:

• Server (server.py)

  • Manages WebSocket connections
  • Verifies JWT tokens
  • Stores messages in a database
  • Broadcasts messages to all connected clients

• Client (client.py)

  • Generates a JWT token
  • Connects to the WebSocket server
  • Sends and receives chat messages asynchronously

---

Features

• Real-time chat using WebSockets
• JWT-based user authentication
• Persistent message storage using SQLite
• Broadcast messaging to all connected clients
• Sends the last 10 stored messages to new clients
• Async and non-blocking architecture
• Graceful client disconnect handling
