Coral-Calculator System Requirements Document

Introduction

The Coral-Calculator project aims to develop a simple, user-friendly calculator application with a single-page design. This calculator will focus on providing basic arithmetic operations, ensuring ease of use and accessibility for users who require straightforward calculations without the complexities of advanced mathematical functions.

System Overview

The Coral-Calculator is designed to be a web-based application that operates on a single page. It will provide users with the ability to perform basic arithmetic operations such as addition, subtraction, multiplication, and division. The application will be optimized for quick access and intuitive use, making it ideal for users who need to perform simple calculations efficiently.

Functional Requirements

• As a User, I should be able to perform addition on two numbers.
• As a User, I should be able to perform subtraction on two numbers.
• As a User, I should be able to perform multiplication on two numbers.
• As a User, I should be able to perform division on two numbers.
• As a User, I should be able to view the calculator on a single page.

User Personas

• User: An individual seeking a simple and efficient tool for basic arithmetic calculations. This user values ease of use and quick access to essential functions without unnecessary complexity.

Signature Design Concept

The Coral-Calculator will feature an interactive, minimalist design concept that emphasizes simplicity and ease of use. The home page will present a sleek, modern calculator interface with large, easy-to-press buttons for each arithmetic operation. The design will incorporate a dynamic background that subtly changes color based on the time of day, providing a visually pleasing experience without distracting from the calculator's functionality. Users will interact with the calculator through smooth animations and transitions powered by framer-motion, enhancing the overall user experience.

Interaction Model & Motion Direction

The landing page for the Coral-Calculator will employ an "animated" interaction model. This approach will include moderate scroll-triggered reveals and hover transitions to enhance the user experience. The calculator's buttons will feature spring physics for a tactile feel, and the interface will incorporate subtle animations to guide users through the calculation process. The focus will be on maintaining a clean and efficient layout, ensuring that users can perform calculations quickly and without distraction.

Non-Functional Requirements

• The application must load within 2 seconds on standard broadband connections.
• The user interface should be responsive and accessible on both desktop and mobile devices.
• The application should handle up to 100 concurrent users without performance degradation.

Tech Stack

• Frontend: React for Web
• Backend: Python with FastAPI
• Database: Not applicable as the application does not require data persistence.
• Local orchestration: Docker
• Server-side orchestration: Kubernetes

Assumptions and Constraints

• The application will not support advanced mathematical functions beyond basic arithmetic.
• The calculator will be designed for single-page use, with no additional navigation or multi-page features.
• The application will be developed with a focus on performance and simplicity.

Glossary

• Arithmetic Operations: Basic mathematical functions including addition, subtraction, multiplication, and division.
• Single-page Design: A web application design where all content is accessible on one page without the need for navigation to other pages.
• Responsive Design: An approach to web design that ensures a website looks and functions well on a variety of devices and screen sizes.
