System Requirements Document for cobalt-todo

Introduction

The purpose of this document is to outline the system requirements for the "cobalt-todo" project. This project aims to develop a minimalistic, single-page todo application designed for personal use. The application will focus on providing a seamless and efficient user experience.

System Overview

The cobalt-todo application is a single-page web application designed to help individuals manage their tasks efficiently. The application will emphasize a minimal design to ensure ease of use and quick interactions. It will be developed with a focus on personal productivity, providing users with a straightforward checklist to manage their daily tasks.

Functional Requirements

• As a User, I should be able to add new tasks to my todo list.
• As a User, I should be able to mark tasks as completed.
• As a User, I should be able to delete tasks from my list.
• As a User, I should be able to view all tasks on a single page.
• As a User, I should experience a minimal design interface.
• As a User, I should interact with the application using a single-page design.

User Personas

• User: An individual looking to manage personal tasks efficiently using a minimalistic todo application.

Visuals Colors and Theme

The color palette for cobalt-todo will reflect its minimalistic and efficient design ethos:

• primary: #1A535C (Deep Teal)
• primary_light: #4ECDC4 (Light Teal)
• secondary: #FF6B6B (Coral Red)
• accent: #FFE66D (Sunny Yellow)
• highlight: #FF9F1C (Vibrant Orange)
• bg: #F7FFF7 (Soft White)
• surface: rgba(26, 83, 92, 0.8) (Teal Surface)
• text: #011627 (Dark Navy)
• text_muted: #7A7A7A (Muted Gray)
• border: rgba(26, 83, 92, 0.2) (Subtle Teal Border)

Signature Design Concept

The cobalt-todo application will feature an interactive "Task Universe" homepage. This concept will transform the user's task list into a dynamic, interactive galaxy. Each task will be represented as a star within this galaxy. Users can click on a star to view or edit task details, drag to rearrange tasks, and hover to see task connections and dependencies. The galaxy will subtly animate, with stars gently pulsing to indicate active tasks. This concept will be implemented using @react-three/fiber for 3D rendering and gsap for smooth animations and transitions.

Interaction Model & Motion Direction

The landing page will employ a "parallax" interaction model, providing a layered depth experience as users scroll through their tasks. Decorative elements will move at different speeds, creating a sense of depth, while the main content remains in the natural flow. This approach will enhance the storytelling aspect of task management, making it visually engaging and intuitive.

Non-Functional Requirements

• The application must load within 2 seconds on a standard broadband connection.
• The application should be responsive and accessible on both desktop and mobile devices.
• The application should maintain data integrity and prevent data loss during interactions.

Tech Stack

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

Assumptions and Constraints

• The application is intended for personal use, not for team or business collaboration.
• The design will prioritize minimalism and simplicity over feature richness.
• The application will be developed as a single-page application to ensure fast interactions.

Glossary

• SPA: Single Page Application
• UI: User Interface
• UX: User Experience
• 3D: Three-Dimensional
• GSAP: GreenSock Animation Platform

This document serves as a comprehensive guide for the development of the cobalt-todo application, ensuring all requirements and design concepts are clearly defined and understood.
