crimson-todo System Requirements Document

Introduction

The purpose of this document is to outline the system requirements for the "crimson-todo" project. This project aims to develop a single-page to-do application with a minimal design, focusing on simplicity and user-friendliness. The application will cater to users who need a straightforward tool for managing tasks efficiently.

System Overview

The "crimson-todo" application will be a web-based platform designed to provide users with a simple and intuitive interface for managing their daily tasks. The application will be developed as a single-page application (SPA) to ensure a seamless user experience with minimal page reloads. The focus will be on delivering a clean and minimalistic design that emphasizes ease of use and clarity.

Functional Requirements

• As a User, I should be able to view a simple list of tasks.
• As a User, I should be able to add new tasks to the list.
• As a User, I should be able to mark tasks as complete.
• As a User, I should be able to delete tasks from the list.

User Personas

• User: An individual looking for a simple and efficient way to manage daily tasks using a minimalistic to-do list application.

Visuals Colors and Theme

Signature Design Concept

For the "crimson-todo" application, the homepage will feature an interactive "Task Canvas" concept. The canvas will display tasks as draggable sticky notes, allowing users to organize their tasks spatially. Users can click and drag notes to rearrange them, providing a tactile and engaging experience. The background will subtly shift colors based on the time of day, using framer-motion for smooth transitions. This dynamic interaction will make task management feel lively and personal.

Interaction Model & Motion Direction

The landing page will utilize a "parallax" interaction model. Layers of the interface will move at different speeds as the user scrolls, creating a sense of depth and engagement. The task list will remain in the normal flow, ensuring easy access and readability. Internal pages will adopt a "static" model to maintain focus on task management without unnecessary distractions.

Non-Functional Requirements

• The application should load within 2 seconds on a standard broadband connection.
• The interface should be responsive and accessible on both desktop and mobile devices.
• The application should support the latest versions of major web browsers.

Tech Stack

• Frontend: React for Web
• Backend: FastAPI
• Database: MySQL or MariaDB, using alembic for migrations
• Local orchestration: Docker, docker-compose

Assumptions and Constraints

• The application will be developed primarily for users in India, considering local preferences and internet speeds.
• The design will prioritize minimalism and ease of use over advanced features.
• The application will not include task categories or complex filtering options.
