Fiery-Calculator System Requirements Document

Introduction

The Fiery-Calculator project aims to develop a simple, user-friendly calculator application with a single-page design. This calculator will focus on basic arithmetic operations, ensuring ease of use and quick access for users who need straightforward calculations without advanced features.

System Overview

The Fiery-Calculator is designed to provide users with a clean and efficient interface for performing basic arithmetic operations such as addition, subtraction, multiplication, and division. The application will be developed as a single-page web application to ensure quick loading times and seamless user experience. The focus is on simplicity and functionality, catering to users who require a no-frills calculator for everyday use.

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.

User Personas

• Basic User: Individuals who need a simple tool for quick arithmetic calculations without any advanced features.

Visuals Colors and Theme

The Fiery-Calculator will feature a unique color palette to enhance its identity:

• primary: #FF5733 (a vibrant fiery orange)
• primary_light: #FF8F66 (a lighter tint of fiery orange)
• secondary: #4A90E2 (a cool blue for contrast)
• accent: #FFC300 (a bright yellow for call-to-action elements)
• highlight: #FF6F61 (a warm coral for hover states and notifications)
• bg: #FFFFFF (a clean white background)
• surface: rgba(255, 255, 255, 0.9) (a slightly opaque white for panels)
• text: #333333 (a dark gray for primary text)
• text_muted: #777777 (a softer gray for secondary text)
• border: rgba(0, 0, 0, 0.1) (a subtle black border)

Signature Design Concept

The Fiery-Calculator will feature an interactive "Fiery Glow" effect on the home page. As users hover over the calculator buttons, a subtle fiery glow will emanate from the buttons, creating an engaging visual effect. This glow will dynamically change in intensity based on the button's function (e.g., operations will have a more intense glow than numbers). The glow effect will be implemented using framer-motion for smooth transitions and spring physics, providing a tactile and responsive feel. This unique interaction will make the calculator not only functional but also visually captivating.

Interaction Model & Motion Direction

The landing page will utilize an "animated" interaction model. This includes moderate scroll-triggered reveals and hover transitions. The calculator buttons will have spring physics applied to them, enhancing the interactive experience. The focus will be on providing a polished and responsive interface that feels lively and engaging.

Non-Functional Requirements

• The application should load within 2 seconds on a standard internet connection.
• The interface should be responsive and accessible on various devices, including desktops, tablets, and smartphones.
• The application should handle user inputs efficiently without lag.

Tech Stack

• Frontend: React for Web
• Backend: Not applicable (client-side only)
• Database: Not applicable (no data storage required)
• AI Models: Not applicable
• Local orchestration: Docker for development environment

Assumptions and Constraints

• The application will not include advanced arithmetic operations or scientific functions.
• The design will focus on a single-page layout to maintain simplicity and ease of use.
• The application will be developed primarily for web use, with no mobile app version planned.

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.
• Framer-motion: A library for creating animations and transitions in React applications.
• Spring physics: A type of animation that mimics the natural motion of objects, providing a more realistic and engaging user experience.
