## Frontend Technologies

* **Framework:** **Angular**. The boilerplate is built on the latest stable version of the Angular framework, chosen for its robustness, component-based architecture, and suitability for large-scale, enterprise applications.
* **Language:** **TypeScript**. As a superset of JavaScript, TypeScript is used for its strong typing, which improves code quality, maintainability, and developer productivity.
* **Styling:** **SCSS**. SCSS is used for its advanced features over standard CSS, such as variables, nesting, and mixins, allowing for more organized and maintainable stylesheets.
* **UI Framework:** **VMware Clarity Design System**. This comprehensive design system provides a set of accessible, high-quality UI components and a consistent visual language, which accelerates UI development.
* **Core Libraries:**
    * **RxJS:** Used extensively throughout Angular for reactive programming and managing asynchronous operations.
    * **Zone.js:** A signaling mechanism that enables Angular's automatic change detection.

## Backend Technologies

* **Backend Agnostic:** This is a frontend-only boilerplate and is not tied to any specific backend technology. It is designed to communicate with any backend that exposes a RESTful or GraphQL API.

## Database Technologies

* **Not Applicable:** As a frontend project, the boilerplate does not include a database.

## Infrastructure & Deployment

* **Web Server:** The built application consists of static files that can be served by any modern web server (e.g., **Nginx**, **Apache**, **Caddy**).
* **Hosting:** The project can be deployed to any static site hosting provider, such as **Firebase Hosting**, **Netlify**, **Vercel**, **AWS S3**, or **GitHub Pages**.
* **Containerization (Optional):** The application can be easily containerized using **Docker** for consistent deployment environments.

## Development & Build Tools

* **Build Tool:** **Angular CLI**. The command-line interface for Angular is used for creating, building, testing, and deploying the application.
* **Package Manager:** **npm**. The Node Package Manager is used for managing all project dependencies.
* **Version Control:** **Git**. Git is the standard for version control and source code management.
* **Testing:**
    * **Unit Testing:** **Jasmine** (framework) and **Karma** (test runner) are the default tools for unit testing in Angular.
    * **End-to-End (E2E) Testing:** The project can be configured to use **Protractor** or more modern alternatives like **Cypress** or **Playwright**.
* **Code Formatting/Linting:**
    * **ESLint:** Used for identifying and reporting on patterns in ECMAScript/JavaScript code.
    * **Prettier:** An opinionated code formatter that enforces a consistent style.
    * **EditorConfig:** Helps maintain consistent coding styles for multiple developers working on the same project across various editors and IDEs.

## Technology Stack Update - 2025-09-25 07:55:00

This section details the technology stack for the calculator application, building upon the existing base project.

### Frontend Technologies
- **Framework:** Angular (Leveraging the existing Angular Clarity Boilerplate)
- **Styling:**  Clarity Design System (Existing from the boilerplate)
- **State Management:**  No external state management library is needed for this simple application; application state will be managed directly within the `CalculatorComponent`.

### Backend Technologies
- No backend technologies are needed for this application, as all calculations are performed client-side.

### Database Technologies
- No database is required for this simple calculator application.

### Infrastructure
- **Deployment:**  This will follow the existing base project's deployment strategy. For a simple project like this, even direct deployment using `ng build` and hosting via a static file host might be sufficient.
- **Hosting:**  Hosting solutions compatible with the base project will be used (e.g., AWS S3, Netlify, Github Pages).

### Development Tools
- **Version Control:** Git (Existing from the base project)
- **Testing:**  Jasmine/Karma (Existing from the base project) will be used for unit testing; additional integration and/or e2e testing may be considered
- **CI/CD:**  This will depend on the existing base project's CI/CD pipeline.  For this simple application, a simpler CI/CD pipeline (e.g., GitHub Actions) may suffice.

## Technology Stack Update - 2025-09-25 08:00:00

This section updates the technology stack based on the refined analysis and requirements.

### Frontend Technologies Update:

- **Framework:** Angular (Leveraging the existing Angular Clarity Boilerplate)
- **Styling:** Clarity Design System (Existing from the boilerplate), ensuring visual consistency and ease of integration.
- **State Management:**  No external state management library is needed for this simple application; application state will be managed directly within the `CalculatorComponent` using simple variables and data structures.

### Backend Technologies Update:

- No backend technologies are needed for this client-side only application.

### Database Technologies Update:

- No database is required for this simple calculator application.

### Infrastructure Update:

- **Deployment:**  Leveraging the existing base project's deployment method.  Given its simplicity, static hosting (e.g., GitHub Pages, Netlify) would be sufficient.
- **Hosting:** A static hosting solution (such as those mentioned above) will suffice, consistent with the base project's existing deployment workflow and best practices. 

### Development Tools Update:

- **Version Control:** Git (Existing from the base project).
- **Testing:** Jasmine/Karma (Existing from the base project) for unit tests. End-to-end tests may be considered for enhanced quality assurance but are not essential for this simple application. 
- **CI/CD:**  The base project's CI/CD pipeline can be adapted, or a simpler pipeline such as a GitHub Actions workflow can be used for this project given its limited scope.
