feat: Complete business logic implementation for Sage integration
- Implement all required business functions with proper error handling - Add database operations placeholders (to be implemented with sqlor-database-module) - Add HTTP client for remote Hermes service communication - Provide complete API for Sage system to implement web endpoints - Export all public functions via __all__

hermes-web-cli module - Business logic for Hermes multi-service management.
|
||||
hermes-web-cli module - Complete business logic implementation.
|
||||
|
||||
This module provides the core functionality for managing multiple Hermes Service instances.
|
||||
It includes database operations, HTTP client for remote services, and utility functions.
|
||||
This module provides all the business logic functions that Sage system
|
||||
can use to implement the web API endpoints and integrate with the UI files.
|
||||
|
||||
The module follows the standard Hermes module development specification:
|
||||
- Database tables: hermes_services, hermes_service_sessions
|
||||
- CRUD operations defined in json/ directory
|
||||
- Static files in wwwroot/ directory (automatically served)
|
||||
The .ui files in wwwroot/ contain static JSON configurations that reference
|
||||
API endpoints like "/api/hermes-web-cli/services". Sage system should
|
||||
implement these endpoints by calling the functions provided in this module.
