Termino: Chat CLI App	A stateless chat application built with Deno.

Termino

Termino is a simple stateless chat application built with Deno. The application allows users to create chat channels, join existing channels, and communicate in real-time using WebSockets.

Features

• Channel Creation: Users can create their own chat channels by specifying a unique channel ID and password.
• Join Existing Channel: Users can join existing channels by providing the correct channel ID and password.
• Real-time Communication: Messages sent within a channel are broadcasted in real-time to all channel members.
• Rate Limiting: Users are limited in the frequency with which they can send messages to prevent spam.
• System Notifications: System notifications are sent to the channel when a user joins or leaves.
• Command-based Interface: The application is controlled via intuitive commands such as /create, /join, and /leave.

Architecture

The application is split into client and server modules:

• Client:
  • Connects to the server through a WebSocket endpoint.
  • Listens for user input, sends commands/messages to the server, and handles server responses.
  • Provides user feedback through the console.
• Server:
  • Handles incoming WebSocket connections.
  • Processes client commands and broadcasts messages.
  • Maintains a channel manager that keeps track of active channels and the clients connected to them.
  • Uses simple rate limiting to prevent frequent message sending by a single user.
