System Requirements Document (SRD)

Project Name: golden-calculator

1. Introduction

The golden-calculator project aims to deliver a simple, one-page calculator application tailored for users in Afghanistan. The application will prioritize ease of use, responsiveness, and a clean design. This document outlines the system requirements to ensure the development aligns with the user's expectations and project goals.

2. System Overview

The golden-calculator is a lightweight, single-page web application designed to perform basic arithmetic operations. It will feature a minimalistic interface, ensuring accessibility and usability for all users. The application will be optimized for both desktop and mobile devices, ensuring seamless functionality across platforms.

Key features include:

• Basic arithmetic operations (addition, subtraction, multiplication, division).
• Responsive design for optimal performance on various screen sizes.
• Aesthetic simplicity to enhance user experience.

The application will be developed with a focus on users in Afghanistan, considering local preferences and usability standards.

3. Functional Requirements

• As a User, I should be able to perform basic arithmetic operations (addition, subtraction, multiplication, division).
• As a User, I should be able to clear the current calculation and start a new one.
• As a User, I should be able to view the results of my calculations in real-time as I input values.
• As a User, I should be able to use the calculator seamlessly on both desktop and mobile devices.

4. User Personas

1. General User
   • Description: Individuals of all ages and technical expertise who require a simple tool for basic calculations.
   • Goals: Perform quick and accurate arithmetic operations.
   • Pain Points: Overly complex interfaces or non-responsive designs.

5. Visuals Colors and Theme

The golden-calculator will adopt a clean and modern aesthetic with the following color scheme:

• Primary Color: Gold (#FFD700) – to reflect the "golden" theme and provide a sense of elegance.
• Secondary Color: White (#FFFFFF) – for a clean and minimalistic background.
• Accent Color: Dark Gray (#333333) – for text and button outlines to ensure readability and contrast.
• Hover/Active States: Light Gold (#FFECB3) – for interactive elements like buttons.

The typography will use a sans-serif font like Roboto or Open Sans for clarity and simplicity.

6. Signature Design Concept

The golden-calculator will feature a "Golden Glow" interactive design.

Home Page / Landing Page Concept:

• The calculator will appear as a floating golden panel in the center of the screen, casting a soft golden glow onto the background.
• The background will be a subtle gradient of white to light gold, giving the impression of sunlight reflecting off a golden surface.
• Buttons will have a 3D pressed effect: when clicked, they will depress slightly and emit a faint ripple animation, like a drop of water hitting a golden surface.
• The display screen will have a digital clock-like appearance, with numbers glowing softly in gold.
• Micro-interactions: Hovering over buttons will cause them to gently pulse, and the calculator will subtly "breathe" (expand and contract slightly) when idle, creating a sense of life and elegance.

This design will make the calculator feel premium and engaging while maintaining simplicity.

7. Non-Functional Requirements

• The application must load within 2 seconds on a standard 3G connection.
• The application must be responsive and function seamlessly on devices with screen sizes ranging from 320px to 1920px.
• The application must support modern browsers, including Chrome, Firefox, Safari, and Edge.
• The application must be accessible, adhering to WCAG 2.1 AA standards.

8. Tech Stack

• Frontend: React (for a responsive and dynamic single-page application).
• Backend: None (as this is a simple calculator, all logic will be handled client-side).
• Database: None (no data storage is required).
• Local Orchestration: Docker (for containerized development and deployment).

9. Assumptions and Constraints

• The application will not require user authentication or data storage.
• The calculator will only support basic arithmetic operations (no scientific or advanced functions).
• The application will be deployed as a web app and will not include a native mobile app.
• The target audience is primarily users in Afghanistan, but the app will be globally accessible.
• The project will adhere to a minimalistic design philosophy, avoiding unnecessary features or complexity.

10. Glossary

• Arithmetic Operations: Basic mathematical functions, including addition, subtraction, multiplication, and division.
• Responsive Design: An approach to web design that ensures the application functions well on devices of various sizes and orientations.
• WCAG 2.1 AA: Web Content Accessibility Guidelines, a standard for making web content more accessible to people with disabilities.
• Micro-interactions: Small, subtle animations or design elements that enhance user experience by providing feedback or visual interest.
