marine-todo System Requirements Document

Introduction

The "marine-todo" project is a single-page to-do application designed with a minimalist approach. This document outlines the system requirements to ensure the application is straightforward, user-friendly, and efficient. The primary focus is on delivering a seamless user experience for managing tasks.

System Overview

The marine-todo application is intended to be a simple, intuitive tool for task management. It will be a single-page application (SPA) that allows users to add, edit, and delete tasks effortlessly. The minimalist design will ensure that users can focus on their tasks without unnecessary distractions. The application will be accessible on various devices, providing a consistent experience across platforms.

Functional Requirements

• As a User, I should be able to add new tasks.
• As a User, I should be able to edit existing tasks.
• As a User, I should be able to delete tasks.
• As a User, I should be able to view all tasks on a single page.

User Personas

• User: The primary user of the marine-todo application, who will manage their tasks using the app. The user values simplicity and efficiency in task management.

Visuals Colors and Theme

The marine-todo application will feature a unique color palette that aligns with its minimalist design ethos:

• primary: #2D3E50 (a deep marine blue)
• primary_light: #4A6572 (a lighter tint of marine blue for hover states)
• secondary: #F9AA33 (a warm amber for headlines and emphasis)
• accent: #FF6F61 (a vibrant coral for CTAs and active states)
• highlight: #FFB74D (a soft orange for hover states and notifications)
• bg: #F5F5F5 (a light grey for the page background)
• surface: rgba(255, 255, 255, 0.9) (a subtle white for card/panel backgrounds)
• text: #212121 (a dark grey for primary text)
• text_muted: #757575 (a muted grey for secondary text)
• border: rgba(0, 0, 0, 0.1) (a subtle black for borders)

Signature Design Concept

The marine-todo application will feature an interactive "Task Wave" design on the homepage. This concept will use a dynamic wave animation that flows across the screen, representing the ebb and flow of task management. Users can interact with the wave by dragging tasks into it to mark them as complete, creating a satisfying ripple effect. The wave will subtly change colors based on the time of day, providing a calming visual experience. This will be achieved using framer-motion for smooth animations and transitions.

Interaction Model & Motion Direction

The landing page will employ a "parallax" interaction model, creating a layered depth effect as users scroll through their tasks. The wave animation will move at a different speed than the task list, enhancing the visual storytelling. Internal pages will maintain a "static" model to prioritize task management efficiency.

Non-Functional Requirements

• The application must load within 2 seconds on a standard internet connection.
• It should be accessible on both desktop and mobile devices.
• The design must adhere to accessibility standards, ensuring usability for all users.

Tech Stack

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

Assumptions and Constraints

• The application will be used primarily by individual users for personal task management.
• The design will focus on simplicity and ease of use, avoiding complex features that detract from the minimalist approach.

Glossary

• SPA: Single-Page Application
• CTA: Call to Action
• Parallax: A scrolling technique that creates a 3D effect by moving background images slower than foreground images.
• Framer-motion: A library for creating animations and transitions in React applications.
