mango-create System Requirements Document

Introduction

The purpose of this document is to outline the system requirements for the "mango-create" project, which involves developing a simple calculator application. This document will serve as a guide for the development and design of the application, ensuring that all necessary functionalities and features are included.

System Overview

The "mango-create" project aims to develop a basic calculator application that performs standard arithmetic operations such as addition, subtraction, multiplication, and division. The application will feature a clean and responsive user interface, making it easy for users to perform calculations efficiently.

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

• User: The primary user of the calculator application who will perform basic arithmetic operations.

Visuals Colors and Theme

The color palette for the "mango-create" project is designed to be fresh and vibrant, reflecting the simplicity and functionality of the calculator.

• primary: #4A90E2 (a calming blue)
• primary_light: #A6C8F0 (a lighter tint of the primary blue)
• secondary: #F5A623 (a warm amber for emphasis)
• accent: #D0021B (a vibrant red for CTAs and active states)
• highlight: #F8E71C (a bright yellow 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 grey for primary text)
• text_muted: #777777 (a softer grey for secondary text)
• border: rgba(0, 0, 0, 0.1) (a subtle grey for borders)

Signature Design Concept

For the "mango-create" project, the signature design concept will feature an interactive calculator interface that mimics a physical calculator. The calculator buttons will have a 3D effect, giving users the sensation of pressing real buttons. When a button is clicked, it will animate with a slight depression and shadow change using framer-motion for realistic feedback. The display screen will have a digital look, with numbers and operations appearing in a smooth, scrolling animation. This interactive design will make the calculator engaging and enjoyable to use.

Interaction Model & Motion Direction

The interaction model for the "mango-create" landing page will be "animated." The calculator interface will feature smooth transitions and animations for button presses and display updates. This approach will enhance user engagement while maintaining a focus on functionality and ease of use.

Non-Functional Requirements

• The application should load quickly and perform calculations with minimal latency.
• The user interface should be responsive and accessible on various devices and screen sizes.
• The application should handle errors gracefully, providing clear feedback to the user.

Tech Stack

• Frontend: React for Web
• Backend: Python with FastAPI
• Database: Not applicable for this project
• AI Models: Not applicable for this project
• Local orchestration: Docker
• Server-side orchestration: Kubernetes

Assumptions and Constraints

• The application will be developed for web platforms only.
• The calculator will not include advanced scientific functions or memory storage.
• The project will adhere to standard web accessibility guidelines.

Glossary

• UI: User Interface
• CTA: Call to Action
• 3D effect: A visual design that gives the illusion of depth and dimension
• Responsive: The ability of a web application to adapt to different screen sizes and devices

This document outlines the requirements and design concepts for the "mango-create" project, ensuring a clear and structured approach to developing a simple yet effective calculator application.
