fiery-a System Requirements Document

1. Introduction

This document outlines the system requirements for the project named "fiery-a," which involves the development of a simple single-page calculator application. The project aims to deliver a user-friendly and efficient calculator interface.

2. System Overview

The "fiery-a" project is designed to provide users with a straightforward calculator application that performs basic arithmetic operations. The application will be accessible via a single-page web interface, ensuring ease of use and quick access.

3. Functional Requirements as Story Points

• As a User, I should be able to perform basic arithmetic operations such as addition, subtraction, multiplication, and division.
• As a User, I should be able to clear the current calculation to start a new one.
• As a User, I should be able to view the result of my calculations immediately after input.
• As a User, I should be able to use a pre-approved API for extended mathematical functions if needed.

4. User Personas

• User: The primary user of the calculator application, seeking a simple and efficient tool for performing arithmetic calculations.

5. Core User Flows

• User opens the calculator application -> Inputs numbers and selects operations -> Views the result -> Clears the calculation for a new operation.

6. Visuals Colors and Theme

• primary: #3498db (a calming blue for primary buttons and accents)
• primary_light: #5dade2 (a lighter blue for hover states)
• secondary: #2ecc71 (a green for secondary buttons)
• accent: #e74c3c (a red for error messages or alerts)
• highlight: #f1c40f (a yellow for active states)
• bg: #ecf0f1 (a light grey for the background)
• surface: #ffffff (white for the calculator surface)
• text: #2c3e50 (a dark blue for primary text)
• text_muted: #95a5a6 (a grey for secondary text)
• border: #bdc3c7 (a subtle grey for borders)

7. Signature Design Concept

The "fiery-a" calculator will feature an interactive, minimalist design where the calculator buttons appear to "press down" with a subtle shadow effect when clicked, providing tactile feedback. The interface will be sleek and modern, with a digital display that animates numbers as they are entered, creating a smooth user experience.

LANDING HERO MOTION BRIEF

The landing page will feature a continuous animation where numbers and operations flow into the calculator display, demonstrating the input and calculation process. The animation will loop every 8 seconds, showing numbers being entered, calculated, and cleared, emphasizing the simplicity and efficiency of the calculator. This will be achieved using motion/react for smooth transitions and animations.

8. Interaction Model & Motion Direction

• Interaction Model: Animated
  • The calculator will feature moderate hover transitions and spring physics on button interactions to enhance user engagement.
  • The landing page will include a continuous 2D motion loop to demonstrate the calculator's functionality.

9. Non-Functional Requirements

• The application must load quickly and perform calculations without noticeable delay.
• The interface should be responsive and accessible on various devices and screen sizes.
• The application must handle errors gracefully, providing clear feedback to the user.

10. Tech Stack

• Frontend: React for Web
• Backend: Pre-approved API for extended functions
• Local Orchestration: Docker

11. Assumptions and Constraints

• The calculator will only perform basic arithmetic operations unless extended functions are explicitly required.
• The application will be developed as a single-page application for simplicity and ease of use.

12. Glossary

• API: Application Programming Interface, used for extending the calculator's functionality.
• Responsive Design: An approach to web design that makes web pages render well on a variety of devices and window or screen sizes.

This document serves as a comprehensive guide for the development of the "fiery-a" calculator project, ensuring all user requirements and design specifications are met.
