swift-start System Requirements Document

Introduction

The purpose of this document is to outline the system requirements for the "swift-start" project, which aims to develop a simple single-page calculator design. This document will provide a comprehensive overview of the system's functional and non-functional requirements, user personas, core user flows, visual design elements, and technical specifications.

System Overview

The "swift-start" project is focused on creating a user-friendly, single-page calculator application. The application will be designed to perform basic arithmetic operations and provide a seamless user experience. The project will prioritize simplicity and ease of use, ensuring that users can quickly perform calculations without unnecessary complexity.

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 current calculation and result on the screen.
• As a User, I should be able to use a decimal point in my calculations.
• As a User, I should be able to handle errors gracefully, such as division by zero.

User Personas

• User: An individual who needs to perform basic arithmetic calculations quickly and efficiently. This persona values simplicity and ease of use in a calculator application.

Core User Flows

1. User opens the calculator application.
2. User inputs numbers and selects an arithmetic operation.
3. User views the result on the screen.
4. User clears the calculation to start a new one if needed.

Visuals Colors and Theme

• primary: #3498db (a calming blue for the main interface)
• primary_light: #85c1e9 (a lighter blue for hover states)
• secondary: #2ecc71 (a green for secondary elements)
• accent: #e74c3c (a red for error messages and alerts)
• highlight: #f1c40f (a yellow for active states)
• bg: #ecf0f1 (a light gray for the background)
• surface: #ffffff (white for the calculator surface)
• text: #2c3e50 (a dark blue for primary text)
• text_muted: #95a5a6 (a muted gray for secondary text)
• border: #bdc3c7 (a subtle gray for borders)

Signature Design Concept

The "swift-start" calculator will feature an interactive design where the buttons appear to press down when clicked, providing tactile feedback to the user. The calculator will have a sleek, modern look with rounded buttons and a digital display that mimics a physical calculator. The design will incorporate smooth transitions and animations using motion/react to enhance the user experience. The interface will be minimalist, focusing on functionality and ease of use.

Landing Hero Motion Brief

The landing page will feature a polished, continuously moving 2D animation built with motion/react. The animation will depict numbers and symbols dynamically flowing into the calculator, which then displays the result of a calculation. This loop will last 10 seconds and will highlight the calculator's ability to handle inputs and produce outputs efficiently. The animation will be responsive and maintain clarity even in reduced-motion settings.

Interaction Model & Motion Direction

The intended interaction model for the landing page is "animated." The page will feature moderate scroll-triggered reveals and hover transitions. The calculator buttons will have spring physics to provide a responsive feel when interacted with. The design will focus on delivering a polished and engaging user experience.

Non-Functional Requirements

• The application must load quickly and be responsive across different devices and screen sizes.
• The design should be intuitive and require minimal user guidance.
• The application must handle errors gracefully and provide clear feedback to the user.

Tech Stack

• Frontend: React for Web
• Backend: Not applicable for a single-page application
• Database: Not applicable for a single-page application
• Local orchestration: Docker
• Server-side orchestration: Not applicable for a single-page application

Assumptions and Constraints

• The calculator will only perform basic arithmetic operations.
• The application will be a single-page design with no backend or database requirements.
• The design will prioritize simplicity and ease of use.

Glossary

• Arithmetic Operations: Basic mathematical operations including addition, subtraction, multiplication, and division.
• Responsive Design: An approach to web design that makes web pages render well on a variety of devices and window or screen sizes.
• Tactile Feedback: A feature that provides a physical response to user interactions, such as the pressing of a button.

This document outlines the requirements and design specifications for the "swift-start" project, ensuring a clear understanding of the project's goals and deliverables.
