jolly-project System Requirements Document

Introduction

The purpose of the jolly-project is to develop a simple, single-page calculator application. This project focuses on providing a user-friendly interface for performing basic arithmetic operations such as addition, subtraction, multiplication, and division. The application is intended for general use without targeting a specific audience.

System Overview

The jolly-project will deliver a web-based calculator that operates on a single page. The design will prioritize simplicity and ease of use, ensuring that users can perform calculations quickly and efficiently. The application will be accessible via web browsers and will not require any advanced operations or features beyond basic arithmetic.

Functional Requirements

• As a User, I should be able to perform 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 result of my calculation instantly.

User Personas

• General User: An individual looking for a straightforward tool to perform basic arithmetic calculations without any advanced features.

Visuals Colors and Theme

The jolly-project will feature a unique color palette to enhance the user experience:

• primary: #4A90E2 (a calming blue for the main interface)
• primary_light: #A6C8F0 (a lighter blue for hover states and secondary UI elements)
• secondary: #F5A623 (a warm amber for headlines and emphasis)
• accent: #D0021B (a vibrant red for call-to-action buttons and active states)
• highlight: #F8E71C (a bright yellow for hover states and notifications)
• bg: #FFFFFF (a clean white for the page background)
• surface: rgba(255, 255, 255, 0.9) (a slightly translucent white for cards/panels)
• text: #333333 (a dark gray for primary text and headings)
• text_muted: #777777 (a softer gray for secondary text and labels)
• border: rgba(0, 0, 0, 0.1) (a subtle gray for borders)

Signature Design Concept

The jolly-project will feature an interactive calculator interface with a unique design concept. The homepage will resemble a sleek, digital notepad where users can input numbers and operations. The calculator buttons will animate with a subtle bounce effect using framer-motion to provide tactile feedback. The background will feature a dynamic gradient that shifts colors based on the time of day, creating a visually appealing experience. Users can drag and drop numbers and operations into the calculation area, making the interaction feel intuitive and engaging.

Interaction Model & Motion Direction

The interaction model for the jolly-project's landing page will be "animated." This includes moderate scroll-triggered reveals and hover transitions, with spring physics applied to interactive elements. The calculator's interface will have smooth animations to enhance user engagement without overwhelming the simplicity of the design.

Non-Functional Requirements

• The application must load quickly and perform calculations instantly.
• The user interface must be responsive and accessible on various devices and screen sizes.
• The design should be intuitive, requiring minimal user guidance.

Tech Stack

• Frontend: React for Web
• Backend: Not applicable (client-side only)
• Database: Not applicable (no data storage required)
• AI Models: Not applicable
• Local orchestration: Docker for development environment

Assumptions and Constraints

• The application will be developed as a single-page application.
• No server-side processing or data storage is required.
• The calculator will only support basic arithmetic operations.

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.
• Arithmetic operations: Basic mathematical operations including addition, subtraction, multiplication, and division.
