# 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.
