Storm-Calculator System Requirements Document

Introduction

The Storm-Calculator project aims to develop a simple, user-friendly calculator that performs basic arithmetic operations. This calculator will be designed as a single-page application, ensuring ease of use and quick access to its functionalities.

System Overview

The Storm-Calculator is a web-based application intended for users who need to perform basic arithmetic calculations. The application will be accessible via a web browser and will feature a clean, intuitive interface that allows users to perform operations such as addition, subtraction, multiplication, and division on a single page.

Functional Requirements

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

User Personas

• Primary User: Individuals who need to perform basic arithmetic calculations quickly and efficiently.

Signature Design Concept

The Storm-Calculator will feature an interactive "floating keypad" design. The calculator buttons will appear to float above the background, casting subtle shadows that give a sense of depth. When a user hovers over a button, it will gently rise and change color, providing tactile feedback. The background will have a soft gradient that shifts slightly as the user interacts with the calculator, creating a dynamic and engaging experience. This effect will be achieved using framer-motion for smooth animations and transitions.

Interaction Model & Motion Direction

The interaction model for the Storm-Calculator will be "animated." The single-page design will incorporate smooth hover transitions and spring physics on interactive elements, ensuring a polished and responsive user experience. The calculator's buttons will animate slightly when pressed, providing visual feedback to the user.

Non-Functional Requirements

• The application should load quickly and be responsive on all modern web browsers.
• The calculator should be accessible and usable on both desktop and mobile devices.
• The design should be intuitive, requiring minimal learning for first-time users.

Tech Stack

• Frontend: React for Web
• Backend: None required for basic operations
• Database: None required for basic operations
• Local orchestration: Docker, docker-compose

Assumptions and Constraints

• The application will be used primarily in India, so it should support local currency and number formatting standards.
• The calculator will not store any user data, so no database is required.
• The application will be developed as a single-page application to ensure simplicity and ease of use.

Glossary

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