Voicebot Module Refactoring

The voicebot/main.py functionality has been broken down into individual Python files for better organization and maintainability:

New File Structure

Core Modules

1. models.py - Data models and configuration

   • VoicebotArgs - Pydantic model for CLI arguments and configuration
   • VoicebotMode - Enum for client/provider modes
   • Peer - WebRTC peer representation
   • JoinRequest - Request model for joining lobbies
   • MessageData - Type alias for message payloads

2. webrtc_signaling.py - WebRTC signaling client functionality

   • WebRTCSignalingClient - Main WebRTC signaling client class
   • Handles peer connection management, ICE candidates, session descriptions
   • Registration status tracking and reconnection logic
   • Message processing and event handling

3. session_manager.py - Session and lobby management

   • create_or_get_session() - Session creation/retrieval
   • create_or_get_lobby() - Lobby creation/retrieval
   • HTTP API communication utilities

4. bot_orchestrator.py - FastAPI bot orchestration service

   • Bot discovery and management
   • FastAPI endpoints for bot operations
   • Provider registration with main server
   • Bot instance lifecycle management

5. client_main.py - Main client logic

   • main_with_args() - Core client functionality
   • start_client_with_reload() - Development mode with reload
   • Event handlers for peer and track management

6. client_app.py - Client FastAPI application

   • create_client_app() - Creates FastAPI app for client mode
   • Health check and status endpoints
   • Process isolation and locking

7. utils.py - Utility functions

   • URL conversion utilities (http_base_url, ws_url)
   • SSL context creation
   • Network information logging

8. main.py - Main orchestration and entry point

   • Command-line argument parsing
   • Mode selection (client vs provider)
   • Entry points for both modes

Key Improvements

• Separation of Concerns: Each file handles specific functionality
• Better Maintainability: Smaller, focused modules are easier to understand and modify
• Reduced Coupling: Dependencies between components are more explicit
• Type Safety: Proper type hints and Pydantic models throughout
• Error Handling: Centralized error handling and logging

Usage

The refactored code maintains the same CLI interface:

# Client mode
python voicebot/main.py --mode client --server-url http://localhost:8000/ai-voicebot

# Provider mode  
python voicebot/main.py --mode provider --host 0.0.0.0 --port 8788

Import Structure

from voicebot import VoicebotArgs, VoicebotMode, WebRTCSignalingClient
from voicebot.models import Peer, JoinRequest
from voicebot.session_manager import create_or_get_session, create_or_get_lobby
from voicebot.client_main import main_with_args

The original main_old.py contains the monolithic implementation for reference.
