spring-idea System Requirements Document

Introduction

The purpose of this document is to outline the system requirements for the "spring-idea" project, which involves the development of a simple, single-page calculator application. The focus is on providing a straightforward interface for general use, supporting basic arithmetic operations.

System Overview

The "spring-idea" project aims to deliver a user-friendly calculator application that operates on a single page. This application will support basic arithmetic operations such as addition, subtraction, multiplication, and division. The design will be minimalistic, ensuring ease of use for a broad audience without any advanced features or specialized audience considerations.

Functional Requirements

• As a User, I should be able to perform addition operations.
• As a User, I should be able to perform subtraction operations.
• As a User, I should be able to perform multiplication operations.
• As a User, I should be able to perform division operations.
• As a User, I should be able to clear the current calculation to start a new one.

User Personas

• General User: Any individual looking to perform basic arithmetic calculations quickly and efficiently.

Core User Flows

1. User opens the calculator application.
2. User inputs numbers and selects an arithmetic operation.
3. User views the result of the calculation.
4. User clears the calculation to perform a new operation.

Visuals Colors and Theme

• primary: #4A90E2 (a calming blue for the main interface)
• primary_light: #A6C8FF (a lighter blue for hover states)
• secondary: #F5A623 (a warm orange for emphasis and highlights)
• accent: #50E3C2 (a vibrant teal for call-to-action buttons)
• highlight: #F8E71C (a bright yellow for notifications and active states)
• bg: #FFFFFF (a clean white for the background)
• surface: rgba(255, 255, 255, 0.9) (a slightly transparent white for panels)
• text: #333333 (a dark gray for primary text)
• text_muted: #888888 (a lighter gray for secondary text)
• border: rgba(0, 0, 0, 0.1) (a subtle gray for borders)

Signature Design Concept

The "spring-idea" calculator will feature an interactive, minimalist design where the calculator buttons animate with a subtle bounce effect when pressed. This will be achieved using framer-motion for smooth spring physics animations. The interface will have a clean, modern look with rounded buttons and a responsive layout that adapts to different screen sizes. The calculator will also include a dynamic display that highlights the current operation being performed, providing users with immediate feedback.

Interaction Model & Motion Direction

• Interaction Model: Animated
  • The calculator will feature moderate animations for button presses and transitions between operations.
  • The design will focus on providing a polished user experience with smooth transitions and responsive feedback.

Non-Functional Requirements

• The application must load quickly and be responsive to user inputs.
• The interface should be intuitive and easy to navigate for users of all ages.
• The application should be compatible with modern web browsers.

Tech Stack

• Frontend: React for Web
• Backend: None required for this simple application
• Database: None required
• Local orchestration: Docker (for development and deployment)

Assumptions and Constraints

• The application will be used primarily on desktop and mobile web browsers.
• No backend or database is required due to the simplicity of the application.
• The design will prioritize simplicity and ease of use over advanced features.

Glossary

• Arithmetic Operations: Basic mathematical operations including addition, subtraction, multiplication, and division.
• Responsive Layout: A design that adjusts smoothly to different screen sizes and orientations.
• Framer-motion: A library used for creating animations and transitions in React applications.
