deep-todo System Requirements Document

Introduction

The purpose of this document is to outline the system requirements for the "deep-todo" project, a simple and user-friendly todo application designed for personal productivity. This document will provide a comprehensive overview of the system, including functional and non-functional requirements, user personas, design concepts, and technical specifications.

System Overview

The "deep-todo" application is intended to serve as a personal productivity tool, allowing users to manage their tasks efficiently. The application will feature a simple checklist style interface with basic CRUD (Create, Read, Update, Delete) operations, task categorization, and a minimal dashboard for easy navigation and task management.

Functional Requirements

• As a User, I should be able to create new tasks.
• As a User, I should be able to view a list of all tasks.
• As a User, I should be able to update existing tasks.
• As a User, I should be able to delete tasks.
• As a User, I should be able to categorize tasks.

User Personas

• User: An individual looking to manage personal tasks and improve productivity through a simple and intuitive interface.

Visuals Colors and Theme

• primary: #1A73E8 (deep blue)
• primary_light: #E8F0FE (light blue)
• secondary: #FF7043 (coral)
• accent: #FFEB3B (vibrant yellow)
• highlight: #FFC107 (amber)
• bg: #FFFFFF (white)
• surface: rgba(250, 250, 250, 0.8)
• text: #212121 (dark gray)
• text_muted: #757575 (light gray)
• border: rgba(0, 0, 0, 0.1)

Signature Design Concept

The "deep-todo" homepage will feature an interactive "Task Galaxy" concept. Users will be greeted with a dynamic 3D galaxy map where each star represents a task. Users can click on a star to open the task card, drag to rotate the galaxy, and hover to highlight task connections. This interactive experience will be built using @react-three/fiber and @react-three/drei for 3D rendering, providing an engaging and memorable first impression.

Interaction Model & Motion Direction

• Interaction Model: Parallax
• The landing page will utilize a parallax interaction model, creating a layered depth effect as users scroll. Decorative elements like atmospheric blobs and distant shapes will move at different speeds, enhancing the storytelling and visual richness of the first impression.
• Internal pages such as the dashboard and task management will maintain a static interaction model for clarity and ease of use.

Non-Functional Requirements

• The application should load within 3 seconds on a standard internet connection.
• The system should be available 99.9% of the time.
• The application should be responsive and accessible on both desktop and mobile devices.

Tech Stack

• Frontend: React for Web
• Backend: Python, FastAPI
• Database: MySQL or MariaDB, using Alembic for migrations
• AI Models: Not applicable
• AI Tools: Not applicable
• Local Orchestration: Docker, docker-compose
• Server-side Orchestration: Kubernetes

Assumptions and Constraints

• The application is designed for individual users, not for team collaboration.
• The system will not include advanced features like recurring tasks or reminders in the initial version.
• The application will be developed with scalability in mind, allowing for future enhancements.

Glossary

• CRUD: Create, Read, Update, Delete
• Parallax: A scrolling technique that creates an illusion of depth by moving background images slower than foreground images.
• 3D Rendering: The process of generating an image from a model by means of computer software.

This document outlines the foundational requirements and design concepts for the "deep-todo" application, setting the stage for development and implementation.
