mango-design System Requirements Document

Introduction

The purpose of this document is to outline the system requirements for the "mango-design" project, which involves creating a single-page, minimalistic calculator for general use. The calculator will support basic arithmetic operations and focus on simplicity and ease of use.

System Overview

The "mango-design" project aims to develop a web-based calculator that operates on a single page with a minimal design. The primary goal is to provide users with a straightforward tool for performing basic calculations without any advanced features. The application will be accessible to a broad audience, ensuring ease of use and quick access to essential arithmetic functions.

Functional Requirements

• 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 input or result.
• As a User, I should be able to view the calculation history on the same page.
• As a User, I should be able to use the calculator on any device with a web browser.

User Personas

• General User: Individuals seeking a simple tool for basic arithmetic calculations. They value ease of use and quick access to essential functions without unnecessary complexity.

Visuals Colors and Theme

The color palette for the "mango-design" project is designed to be minimal yet visually appealing, ensuring a pleasant user experience:

• primary: #4A90E2 (a calm blue for the main interface elements)
• primary_light: #A6C8FF (a lighter blue for hover states and secondary UI)
• secondary: #FF6F61 (a warm coral for emphasis and links)
• accent: #F5A623 (a vibrant orange for CTAs and active states)
• highlight: #F8E71C (a bright yellow for hover states and notifications)
• bg: #FFFFFF (a clean white for the page background)
• surface: rgba(255, 255, 255, 0.9) (a subtle white for card/panel backgrounds)
• text: #333333 (a dark gray for primary text)
• text_muted: #777777 (a softer gray for secondary text and labels)
• border: rgba(0, 0, 0, 0.1) (a light gray for borders)

Signature Design Concept

The homepage of the "mango-design" calculator will feature an interactive, minimalist design that enhances user engagement. The concept is a "floating keypad" where each button slightly elevates and casts a shadow when hovered over, providing a tactile feel. The background will subtly shift colors based on the time of day, using a gradient transition from light blue in the morning to a soft orange in the evening. This effect will be achieved using framer-motion for smooth animations and transitions. Users can drag the keypad to reposition it within the page, offering a customizable experience. The design will be responsive, ensuring functionality across all devices.

Interaction Model & Motion Direction

The interaction model for the "mango-design" calculator will be "animated." This approach will include moderate scroll-triggered reveals and hover transitions, providing a polished user experience. The calculator will feature spring physics on interactive elements, enhancing the tactile feel of the interface. The design will prioritize layout clarity while incorporating subtle animations to maintain user engagement.

Non-Functional Requirements

• The application should load within 2 seconds on a standard internet connection.
• The calculator must be responsive and function correctly on various screen sizes and devices.
• The design should adhere to accessibility standards, ensuring usability for individuals with disabilities.

Tech Stack

• Frontend: React for Web
• Backend: Python with FastAPI
• Database: Not applicable for this project as it is a single-page application without data persistence.
• AI Models: Not applicable
• Local orchestration: Docker
• Server-side orchestration: Kubernetes

Assumptions and Constraints

• The calculator will not support advanced mathematical functions or scientific calculations.
• The application will be hosted on a cloud platform to ensure scalability and reliability.
• The design will focus on minimalism, avoiding any unnecessary visual elements that could detract from usability.

Glossary

• Single-page design: A web application that operates entirely on one page, without the need for navigation to other pages.
• Minimal design: A design approach that emphasizes simplicity and the removal of unnecessary elements.
• Responsive design: An approach to web design that ensures a site or application looks and functions well on a variety of devices and screen sizes.
