turbo-start System Requirements Document

1. Introduction

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

2. System Overview

The turbo-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.

3. 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 input to start a new calculation.
• As a User, I should be able to view the result of my calculation immediately after entering an operation.

4. User Personas

• User: A general user who needs to perform basic arithmetic calculations quickly and efficiently.

5. Core User Flows

• User opens the calculator -> enters numbers and operations -> views the result -> clears input for a new calculation.

6. Visuals Colors and Theme

[Default — not specified by user]

• primary: #3498db (a calming blue for the main interface)
• primary_light: #85c1e9 (a lighter blue for hover states)
• secondary: #2ecc71 (a green for secondary actions)
• accent: #e74c3c (a red for error states or important alerts)
• highlight: #f1c40f (a yellow for hover states and notifications)
• bg: #ecf0f1 (a light grey for the background)
• surface: #ffffff (white for the calculator surface)
• text: #2c3e50 (dark grey for primary text)
• text_muted: #7f8c8d (muted grey for secondary text)
• border: #bdc3c7 (a subtle grey for borders)

7. Signature Design Concept

The turbo-start calculator will feature an interactive, minimalist design where the buttons appear to "press" down when clicked, providing tactile feedback. The interface will be clean and uncluttered, with a digital display at the top showing the current input and result. The calculator will have a modern aesthetic with rounded buttons and smooth transitions.

Landing Hero Motion Brief

The calculator interface will have a smooth animation where numbers and operations appear to "slide" into the display area when pressed. This animation will be continuous and loop seamlessly, creating a dynamic and engaging user experience. The interface will be responsive, adjusting to different screen sizes while maintaining its functionality and aesthetic appeal.

8. Interaction Model & Motion Direction

• Interaction Model: Animated
  • The calculator will feature moderate hover transitions and spring physics on button presses to enhance user interaction.
  • The interface will be static for the main calculation area, ensuring clarity and ease of use.

9. Non-Functional Requirements

• The calculator must load quickly and be responsive across different devices and screen sizes.
• The interface should be intuitive and easy to use, requiring minimal user instruction.

10. Tech Stack

[Default — not specified by user]

• Frontend: React for Web
• Backend: Not applicable for a single-page application
• Database: Not applicable for a single-page application

11. Assumptions and Constraints

• The calculator will not require persistent data storage as it is a single-page application.
• The application will be designed for use in a web browser and will not require a backend server.

12. Glossary

• Single-page application (SPA): A web application that interacts with the user by dynamically rewriting the current page rather than loading entire new pages from the server.
• Responsive design: An approach to web design that makes web pages render well on a variety of devices and window or screen sizes.
