Cosmic-Application System Requirements Document

Introduction

The purpose of this document is to outline the system requirements for the "cosmic-application," a simple, single-page to-do application designed for personal use. The focus is on minimalism and user-friendly design, ensuring a seamless experience for users who need a straightforward task management tool.

System Overview

The cosmic-application is a personal to-do list application that operates on a single-page interface. It is designed to be minimalistic, providing users with a clean and efficient way to manage their tasks without unnecessary complexity. The application will allow users to create, read, update, and delete tasks in a simple and intuitive manner.

Functional Requirements

• As a User, I should be able to add new tasks to my to-do list.
• As a User, I should be able to view all my tasks on a single page.
• As a User, I should be able to edit existing tasks.
• As a User, I should be able to delete tasks that are no longer needed.

User Personas

• User: An individual looking for a simple and efficient way to manage personal tasks without additional features or complexities.

Visuals Colors and Theme

• primary: #2C3E50 (a deep slate blue for a calming effect)
• primary_light: #34495E (a lighter slate blue for hover states)
• secondary: #E74C3C (a vibrant coral for emphasis and links)
• accent: #F39C12 (a bright orange for call-to-action buttons)
• highlight: #F1C40F (a warm gold for notifications and active states)
• bg: #ECF0F1 (a light grey for the background to ensure readability)
• surface: rgba(255, 255, 255, 0.9) (a soft white for cards and panels)
• text: #2C3E50 (the primary text color for readability)
• text_muted: #95A5A6 (a muted grey for secondary text)
• border: rgba(44, 62, 80, 0.2) (a subtle border color for delineation)

Signature Design Concept

The cosmic-application will feature a unique interactive design concept called "Task Galaxy." The homepage will present a cosmic-themed interface where each task is represented as a star in a galaxy. Users can click on a star to open a task card, drag to rotate the galaxy cluster, and hover over stars to highlight connections between related tasks. This interactive design will be implemented using @react-three/fiber and @react-three/drei for 3D effects, creating an engaging and memorable user experience.

Interaction Model & Motion Direction

The landing page will utilize a "parallax" interaction model to create a sense of depth and immersion. As users scroll, different layers of the cosmic background will move at varying speeds, enhancing the visual storytelling. The application will also feature moderate scroll-triggered reveals and hover transitions to maintain a polished and dynamic interface.

Non-Functional Requirements

• The application must load quickly and perform efficiently on various devices.
• The design should be responsive and adapt to different screen sizes.
• The user interface should be intuitive and require minimal learning time.

Tech Stack

• Frontend: React for Web
• Backend: Python with FastAPI
• Database: MySQL or MariaDB, using Alembic for migrations
• Local Orchestration: Docker and docker-compose

Assumptions and Constraints

• The application is intended for personal use and does not require multi-user support.
• The design will focus on simplicity and ease of use, without additional features like task categorization or reminders.
• The application will be developed as a single-page application to ensure a seamless user experience.

Glossary

• CRUD: Create, Read, Update, Delete - basic operations for managing tasks.
• 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.
• Parallax: A scrolling technique used to create an illusion of depth by moving background images slower than foreground images.
