proud-calculator System Requirements Document

1. Introduction

The "proud-calculator" project aims to develop a simple, single-page calculator focused on basic arithmetic operations. This project is designed to provide users with a clean and straightforward interface for quick calculations without the complexity of advanced features.

2. System Overview

The proud-calculator is intended to be a user-friendly tool for performing basic arithmetic operations such as addition, subtraction, multiplication, and division. The system will be implemented as a single-page application, ensuring that users can access all functionalities without navigating through multiple screens. The design will prioritize simplicity and ease of use, making it suitable for personal and educational purposes.

3. Functional Requirements

• As a User, I should be able to perform addition, subtraction, multiplication, and division.
• As a User, I should be able to view the results of my calculations instantly.
• As a User, I should be able to clear the current calculation to start a new one.

4. User Personas

• General User: Individuals who need a simple tool for performing basic arithmetic calculations quickly and efficiently.

5. Visuals Colors and Theme

The proud-calculator will feature a unique color palette to enhance its visual appeal while maintaining simplicity:

• primary: #2A9D8F (a calming teal)
• primary_light: #A8DADC (a lighter tint of teal for hover states)
• secondary: #E76F51 (a warm coral for emphasis)
• accent: #F4A261 (a vibrant orange for CTAs and active states)
• highlight: #E9C46A (a golden hue for notifications and active indicators)
• bg: #F1FAEE (a soft, off-white background)
• surface: rgba(42, 157, 143, 0.8) (a semi-transparent teal for panels)
• text: #264653 (a deep blue for primary text)
• text_muted: #6D6875 (a muted gray for secondary text)
• border: rgba(233, 111, 81, 0.2) (a subtle coral border)

6. Signature Design Concept

The proud-calculator will feature an interactive "floating keypad" design. The calculator's buttons will appear to float above the background, casting subtle shadows for a 3D effect. When a user hovers over a button, it will gently rise and change color, providing tactile feedback. The background will feature a soft gradient that shifts subtly as users interact with the calculator, creating a dynamic and engaging experience. This concept will be implemented using framer-motion for smooth animations and transitions.

7. Interaction Model & Motion Direction

The landing page for the proud-calculator will utilize a "static" interaction model. This approach ensures that the focus remains on the calculator's functionality, providing a clear and distraction-free user experience. The use of framer-motion will add subtle animations to enhance user interactions without overwhelming the simplicity of the design.

8. Non-Functional Requirements

• The calculator should load quickly and be responsive across different devices.
• The user interface should be intuitive and require no learning curve.
• The application should handle basic arithmetic operations accurately and efficiently.

9. Tech Stack

• Frontend: React for Web
• Backend: Not applicable (single-page application)
• Database: Not applicable
• AI Models: Not applicable
• Local orchestration: Docker
• Server-side orchestration: Not applicable

10. Assumptions and Constraints

• The calculator will only support basic arithmetic operations.
• The application will be designed for personal and educational use.
• The project will not include advanced features such as scientific calculations or graphing.

11. Glossary

• Arithmetic Operations: Basic mathematical operations including addition, subtraction, multiplication, and division.
• Single-page Application: A web application that interacts with the user by dynamically rewriting the current page, rather than loading entire new pages from the server.

This document outlines the system requirements for the proud-calculator project, focusing on delivering a simple, efficient, and visually appealing tool for basic arithmetic calculations.
