4. Module System

Last Updated: May 20, 2025

Overview

The Module System is the foundation of the Typus Development Framework's architecture. It provides a structured way to organize code, extend functionality, and maintain separation of concerns throughout the application.

What are Modules?

Modules are self-contained units of functionality that encapsulate related features, business logic, and UI components. They serve as building blocks that can be combined to create complex applications while maintaining clean architecture.

Key Benefits

• Separation of Concerns: Each module focuses on a specific domain or feature
• Code Organization: Logical grouping of related functionality
• Maintainability: Changes to one module don't affect others
• Reusability: Modules can be reused across different projects
• Extensibility: New features can be added as modules without modifying core code
• Testability: Modules can be tested in isolation

Module Types

The framework supports two primary types of modules:

Backend Modules

Backend modules provide server-side functionality:

• API Endpoints: Define REST API routes and handlers
• Business Logic: Implement domain-specific operations
• Data Access: Manage database interactions
• Service Integration: Connect to external services

Backend modules are automatically discovered and registered at application startup, with routes dynamically created based on the module's configuration.

Frontend Modules

Frontend modules provide client-side functionality:

• UI Components: Reusable interface elements
• Pages: Full page implementations
• Navigation: Menu entries and routing
• State Management: Module-specific data handling
• API Integration: Communication with backend services

Frontend modules are loaded on-demand, allowing for efficient application loading and performance.

Module Communication

Modules can communicate with each other through well-defined interfaces:

• Events: Publish/subscribe pattern for loose coupling
• Service Injection: Dependency injection for direct communication
• Shared State: Access to global or shared state stores

Common Module Examples

Authentication Module

Handles user authentication, authorization, and session management:

• User registration and login
• Password management
• Role-based access control
• Session tracking

Content Management Module

Provides tools for managing website content:

• Content creation and editing
• Media management
• Content categorization
• Publishing workflow

Notification Module

Manages system and user notifications:

• In-app notifications
• Email notifications
• Push notifications
• Notification preferences

Conclusion

The Module System provides a powerful foundation for building scalable and maintainable applications. By organizing code into cohesive modules with clear responsibilities, the Typus Development Framework enables developers to create complex applications that remain manageable as they grow.
