sweet-project System Requirements Document

Introduction

The purpose of this document is to outline the system requirements for the "sweet-project," which involves creating a simple single-page design for a calculator. The project aims to deliver a straightforward and user-friendly interface.

System Overview

The sweet-project is a web-based application designed to provide users with a simple and intuitive calculator interface. The application will be accessible via web browsers and will focus on delivering essential calculator functionalities without unnecessary complexity.

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 to start a new calculation.
• As a User, I should be able to view the result of my calculations immediately after entering the operation.
• As a User, I should be able to use a single-page layout for all calculator interactions without navigating through multiple pages or sidebars.

User Personas

• User: An individual looking for a simple and efficient tool to perform basic arithmetic calculations quickly.

Core User Flows

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

Visuals Colors and Theme

• primary: #3498db (a calming blue for the main interface)
• primary_light: #85c1e9 (a lighter blue for hover states)
• secondary: #e74c3c (a contrasting red for emphasis and alerts)
• accent: #f1c40f (a vibrant yellow for call-to-action buttons)
• highlight: #f39c12 (an orange for active indicators)
• bg: #ecf0f1 (a light grey for the background)
• surface: rgba(255, 255, 255, 0.9) (a soft white for panels)
• text: #2c3e50 (a dark blue for primary text)
• text_muted: #7f8c8d (a muted grey for secondary text)
• border: rgba(44, 62, 80, 0.2) (a subtle border color)

Signature Design Concept

The sweet-project will feature an interactive calculator interface that mimics a physical calculator. The design will include large, tactile buttons that animate slightly when pressed, providing a satisfying user experience. The background will have a subtle gradient that shifts slightly as users interact with the calculator, creating a dynamic and engaging visual effect. This will be achieved using framer-motion for button animations and gsap for background transitions.

Interaction Model & Motion Direction

The landing page will employ an "animated" interaction model. The calculator buttons will have hover transitions and spring physics to enhance user interaction. The background will subtly animate to provide a polished and engaging experience.

Non-Functional Requirements

• The application should load quickly and respond to user inputs without noticeable delay.
• The design should be responsive and work well on various screen sizes, including mobile devices.

Tech Stack

• Frontend: React for Web
• Backend: Not applicable for this project as it is a client-side application.
• Database: Not applicable for this project as it does not require data storage.

Assumptions and Constraints

• The application will be developed as a single-page application.
• No backend or database is required as the calculator functions entirely on the client side.

Glossary

• SPA: Single Page Application, a web application that interacts with the user by dynamically rewriting the current page rather than loading entire new pages from the server.
• UI: User Interface, the space where interactions between humans and machines occur.
