Product Requirements Document (PRD) - Angular Clarity Boilerplate

1. Product Vision

To provide a robust, scalable, and feature-rich boilerplate that serves as a foundational template for building modern, enterprise-grade web applications using Angular and the VMware Clarity Design System. The vision is to accelerate the development lifecycle by offering a pre-configured, best-practice project structure.

2. Target Audience

The primary target audience consists of Angular developers and development teams who require a standardized, efficient, and consistent starting point for new projects. This includes:

Enterprise Development Teams: Teams that need to maintain a consistent look and feel across multiple applications.
Independent Developers: Individuals looking to quickly bootstrap new projects without spending significant time on initial setup and configuration.

3. User Stories (Developer Stories)

User Story 1: Quick Project Initialization

As a developer, I want to clone the repository and run npm install and ng serve to get a live development server running, so that I can bypass manual setup and start building features immediately.
Acceptance Criteria:
- Given I have Node.js and Angular CLI installed,
- When I clone the repository, install dependencies, and run the start command,
- Then the application compiles successfully and is accessible in my browser at localhost:4200.

User Story 2: Add a New Feature

As a developer, I want to create a new lazy-loaded feature module with its own components and routing, so that I can add new sections to the application in a scalable way.
Acceptance Criteria:
- Given the boilerplate is running,
- When I use the Angular CLI to generate a new module and add it to the main routing configuration,
- Then I can navigate to the new feature's route, and its components are rendered correctly.

User Story 3: Utilize Shared Components

As a developer, I want to use a component from the SharedModule within a new feature module, so that I can reuse common UI elements and maintain consistency.
Acceptance Criteria:
- Given I have a new feature module,
- When I import the SharedModule into my feature module,
- Then I can use the shared components (e.g., a custom card or loader) in my feature's templates without errors.

4. Functional Requirements

FR-001: Pre-configured Angular Environment: A ready-to-use Angular CLI project with all necessary dependencies and build configurations.
FR-002: Clarity Design System Integration: Full integration of Clarity UI components and styles, ready for immediate use.
FR-003: Scalable Architecture: A modular structure featuring a CoreModule for singleton services and a SharedModule for reusable UI components, directives, and pipes.
FR-004: Responsive Layout: A default application shell with a responsive header, navigation sidebar, and main content area.
FR-005: Routing: A pre-configured routing module with examples of lazy-loaded feature modules.
FR-006: Theming: Basic support for Clarity's light and dark themes.

5. Non-Functional Requirements

NFR-001: Performance: The initial boilerplate should be lightweight, ensuring fast development server startup times and optimized production builds.
NFR-002: Usability (Developer Experience): The codebase must be clean, well-commented, and logically organized to provide an excellent developer experience.
NFR-003: Maintainability: The modular architecture must facilitate easy updates to dependencies and allow for the addition of new features without introducing breaking changes to the core structure.
NFR-004: Scalability: The architecture is designed to support the growth of large, enterprise-scale applications.
NFR-005: Extensibility: The boilerplate should be easy to customize and extend with additional libraries, modules, and configurations as per project-specific needs.

6. Out of Scope

The following features and functionalities are explicitly out of scope for the boilerplate:

Backend Implementation: This is a frontend-only boilerplate and does not include any backend code or database.
Authentication/Authorization Logic: While the architecture supports the implementation of security features, no pre-built authentication or authorization logic is included.
State Management: The boilerplate does not include a state management library (e.g., NgRx, Akita) by default, allowing developers to choose the best solution for their needs.
Business Logic: No specific business logic or application features are included beyond the basic structural components.
CI/CD Pipelines: While the project is ready for CI/CD, no pre-configured pipelines are included.
