ComfyUI-Manager: Core Backend (glob)

This directory contains the Python backend modules that power ComfyUI-Manager, handling the core functionality of node management, downloading, security, and server operations.

Directory Structure

• glob/ - code for new cacheless ComfyUI-Manager
• legacy/ - code for legacy ComfyUI-Manager

Core Modules

• manager_core.py: The central implementation of management functions, handling configuration, installation, updates, and node management.
• manager_server.py: Implements server functionality and API endpoints for the web interface to interact with the backend.

Specialized Modules

• share_3rdparty.py: Manages integration with third-party sharing platforms.

Architecture

The backend follows a modular design pattern with clear separation of concerns:

1. Core Layer: Manager modules provide the primary API and business logic
2. Utility Layer: Helper modules provide specialized functionality
3. Integration Layer: Modules that connect to external systems

Security Model

The system implements a comprehensive security framework with multiple levels:

• Block: Highest security - blocks most remote operations
• High: Allows only specific trusted operations
• Middle: Standard security for most users
• Normal-: More permissive for advanced users
• Weak: Lowest security for development environments

Implementation Details

• The backend is designed to work seamlessly with ComfyUI
• Asynchronous task queuing is implemented for background operations
• The system supports multiple installation modes
• Error handling and risk assessment are integrated throughout the codebase

API Integration

The backend exposes a REST API via manager_server.py that enables:

• Custom node management (install, update, disable, remove)
• Model downloading and organization
• System configuration
• Snapshot management
• Workflow component handling
