Architecture Concept Overview

This document provides a conceptual overview of the architecture used in the private ShadowSystem repository. The system uses a modern feature-based architecture built on Angular 17 to ensure modularity, high cohesion, and scalable maintainability for a custom company dashboard.

(Note: The actual source code is private. This overview illustrates the design patterns implemented.)

Architecture Layers

1. core layer

The core layer conceptually handles singleton services, application-wide configuration, and critical infrastructure.

  • Guards: Concepts like session validation and RBAC (Role-Based Access Control) access validation.
  • Interceptors: Handling token attachment, automatic refreshes, and global loading states.
  • State/Services: Global configuration and authentication state management.

2. features layer

The heart of the application business logic. Each feature domain conceptually encapsulates its own routing, components, and data-access layer.

  • Domains: Includes modules for authentication, clients, contracts, accounting, and reports.
  • Features interact through shared concepts or routing, intentionally avoiding deep cross-feature coupling to prevent circular dependencies.

3. shared layer

Houses highly reusable UI components, pipes, directives, and generic utilities utilized across multiple feature domains.

  • Examples include standard table wrappers, generic confirmation dialogs, and specific UI elements.
  • Contains no domain-specific business logic.

4. layout layer

Manages the structural skeleton of the application.

  • Components: Represents the desktop sidebar navigation, off-canvas mobile navigation, and global asynchronous loading indicators.

data-access pattern

  • Services: API interactions are strictly localized within data-access boundaries inside each specific feature.
  • Models and DTOs:
    • Domain objects are utilized internally by UI components.
    • Data Transfer Objects (DTOs) define the exact payload shape sent to or received from the backend API. This separation creates a safe boundary if API contracts change.

Routing Strategy

The system embraces modern standalone routing concepts. Feature modules lazily load their own distinct route configurations, minimizing the initial JavaScript bundle size and optimizing application startup times.
