## Project Overview
The project is an **Angular Clarity Boilerplate**, designed to serve as a foundational template for building modern, scalable, and feature-rich web applications. It provides a pre-configured Angular project integrated with the VMware Clarity Design System, enabling developers to kickstart new projects with a robust and consistent architecture, thereby accelerating the development lifecycle.

## Business Analysis
The primary business need is to **streamline the initial setup phase of new Angular projects** within an organization or for individual developers. The target audience is **Angular developers and development teams** who require a standardized, best-practice project structure. The value proposition is centered around increasing development efficiency, enforcing UI/UX consistency through the Clarity Design System, and reducing the boilerplate code that developers need to write for every new project.

## User Requirements (Developer Requirements)
The "users" of this boilerplate are developers. Their core requirements are:
- Developers must be able to **quickly set up a new project** by cloning the repository and installing dependencies.
- Developers must be provided with a **clear and understandable project structure** that promotes scalability and maintainability.
- The boilerplate must include a **pre-built, responsive application layout** (e.g., header, sidebar, content area).
- Developers must have access to **pre-configured core and shared modules** for common functionalities like services, guards, and reusable components.
- The boilerplate must be **easily extendable** with new feature modules and components.

## Functional Requirements
The boilerplate will provide the following functional capabilities out-of-the-box:

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

## Non-Functional Requirements

- **Performance:** The initial boilerplate should be lightweight, ensuring fast development server startup times and optimized production builds.
- **Usability (Developer Experience):** The codebase must be clean, well-commented, and logically organized to provide an excellent developer experience.
- **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.
- **Scalability:** The architecture is designed to support the growth of large, enterprise-scale applications.
- **Extensibility:** The boilerplate should be easy to customize and extend with additional libraries, modules, and configurations as per project-specific needs.

## 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.

## Business Rules (Architectural Principles)
- Singleton services (e.g., logging, authentication) must be provided in the `CoreModule`.
- Reusable components, pipes, and directives that do not have a dependency on services must be declared and exported in the `SharedModule`.
- All major application features should be encapsulated within their own lazy-loaded modules.
- Environment-specific variables (e.g., API endpoints) must be managed in the `environments` folder.

### Project Overview
The project aims to develop a simple web-based Notes Application. Users will be able to perform fundamental operations such as creating, editing, and deleting text-based notes. A key requirement is that all data persistence will be managed using the browser's local storage mechanism, eliminating the need for a traditional backend database for this initial scope. The application will leverage standard frontend web technologies (HTML, CSS, JavaScript) and will be integrated into the `frontend/` directory of the existing Angular Clarity Boilerplate base project, as guided by the `io8codermaster_breakdown.md` and `io8codermaster_plan.md` documents.

### Business Analysis
This Notes App serves a straightforward user need: a personal, lightweight tool for jotting down and managing simple text notes. The primary value proposition is its simplicity, direct access (no login required), and local persistence, making it suitable for quick personal organization without reliance on external services. The target audience is any individual needing a basic digital scratchpad. Given the local storage constraint, the application is designed for single-user, single-browser instance usage. It provides a foundational utility that can be extended in the future but focuses on the core CRUD functionality for immediate usability. This aligns with the `io8codermaster_breakdown.md`'s focus on core features and local storage.

### User Requirements
Based on the user prompt and `io8codermaster_breakdown.md`, the core user requirements are:
*   **Note Creation:** Users need to create new text notes, providing a title and content.
*   **Note Content:** Each note must capture a title, its main text content, and automatically record the date it was created.
*   **Note Management:** Users must be able to view a list of all their existing notes.
*   **Note Editing:** Users need the ability to modify the title and/or content of an existing note.
*   **Note Deletion:** Users must be able to remove unwanted notes.
*   **Data Persistence:** All created, edited, and deleted notes must be saved and retrieved reliably using local storage, ensuring data is retained across browser sessions for the same user.

### Functional Requirements
*   **Note Data Model:** The application shall define a `Note` object structure including `id` (unique), `title` (string), `content` (string), and `dateCreated` (string/timestamp), as specified in `io8codermaster_plan.md`.
*   **Note Creation Interface:** Provide a UI form with input fields for 'Title' and 'Content' and a 'Save' button to submit new notes.
*   **Unique ID Generation:** Automatically generate a unique identifier for each new note.
*   **Date Stamping:** Automatically record the current date/time when a note is created.
*   **Note Storage (Create):** Persist new notes to the browser's local storage upon creation using the `localStorageService.js` as outlined in `io8codermaster_plan.md`.
*   **Note Listing Display:** Display all notes retrieved from local storage in a clear, ordered list format on the main application interface.
*   **Note Retrieval (Read):** Load all existing notes from local storage upon application initialization via `localStorageService.js`.
*   **Note Editing Interface:** Provide a mechanism (e.g., 'Edit' button) to select a note, populate an edit form with its current data, and save updated content.
*   **Note Storage (Update):** Update the corresponding note's data in local storage when modifications are saved.
*   **Note Deletion Mechanism:** Include a 'Delete' button or similar control for each note, allowing users to remove it.
*   **Note Storage (Delete):** Remove the selected note from local storage upon deletion confirmation.
*   **UI Refresh:** The display of notes shall automatically update after creation, editing, or deletion operations.

### Non-Functional Requirements
*   **NFR-001: Usability:** The user interface for note creation, viewing, editing, and deletion shall be intuitive and easy to navigate for users with basic web literacy.
*   **NFR-002: Performance:** Note creation, retrieval, updates, and deletions shall be responsive, with operations completing within acceptable browser interaction times (e.g., under 500ms for typical operations).
*   **NFR-003: Data Integrity:** Notes stored in local storage shall be correctly retrieved without corruption. Data consistency must be maintained across CRUD operations.
*   **NFR-004: Persistence:** All notes saved in local storage must persist across browser sessions until explicitly deleted by the user, as dictated by the local storage constraint in `io8codermaster_breakdown.md`.
*   **NFR-005: Accessibility:** (Basic) The application should follow standard web practices to ensure basic accessibility (e.g., clear labels, keyboard navigation where applicable).
*   **NFR-006: Browser Compatibility:** The application should function correctly on modern web browsers that support `localStorage` (e.g., Chrome, Firefox, Safari, Edge).
*   **NFR-007: Error Handling:** The application shall provide basic feedback to the user in case of local storage issues (e.g., full storage) or input validation errors (e.g., empty title).

### User Stories
*   **US-001: Create a Note**
    *   **As a user,** I want to be able to input a title and content for a new note, **so that** I can capture a thought or idea.
    *   **Acceptance Criteria:**
        *   The application displays a form with fields for 'Title' and 'Content'.
        *   I can enter text into both fields.
        *   Upon clicking a 'Save' button, a new note is created with the provided title and content, a unique ID, and the current date/time.
        *   The new note appears in the list of notes.
        *   The form clears after saving.
*   **US-002: View All Notes**
    *   **As a user,** I want to see a list of all my previously saved notes, **so that** I can easily review them.
    *   **Acceptance Criteria:**
        *   When the application loads, all notes saved in local storage are displayed.
        *   Each note in the list shows its title and a snippet of its content.
        *   Notes are displayed in a readable format.
*   **US-003: Edit an Existing Note**
    *   **As a user,** I want to modify the title or content of an existing note, **so that** I can update my thoughts or correct mistakes.
    *   **Acceptance Criteria:**
        *   Each displayed note has an 'Edit' option.
        *   Clicking 'Edit' for a note populates the note creation/edit form with that note's current title and content.
        *   I can change the title and/or content in the form.
        *   Upon clicking a 'Save'/'Update' button, the corresponding note in the list and local storage is updated with the new information.
        *   The list of notes reflects the updated content.
*   **US-004: Delete a Note**
    *   **As a user,** I want to remove a note that I no longer need, **so that** I can keep my notes organized.
    *   **Acceptance Criteria:**
        *   Each displayed note has a 'Delete' option.
        *   Clicking 'Delete' for a note removes it from the displayed list and from local storage.
        *   The application does not display the deleted note anymore.

### Business Rules
*   **BR-001: Required Fields:** A note's title cannot be empty when saved. If the title is empty, the user should be prompted to provide one.
*   **BR-002: Unique Identifiers:** Each note must have a unique identifier (ID).
*   **BR-003: Date Created Immutability:** The `dateCreated` field for a note is set only once upon initial creation and should not be editable by the user.
*   **BR-004: Local Storage Limits:** The application must gracefully handle potential local storage capacity limits, though explicit user feedback might be limited to a generic error message.
*   **BR-005: Data Scope:** The application is designed for single-user, browser-local data storage. Data is not synchronized across different browsers or devices, aligning with the `io8codermaster_breakdown.md`'s constraints.
