mellow-webapp System Requirements Document

Introduction

The purpose of this document is to outline the system requirements for the "mellow-webapp," a minimalist todo web application designed with a single-page layout. The focus is on simplicity and user-friendliness, ensuring users can manage their tasks efficiently without unnecessary features or distractions.

System Overview

The mellow-webapp is a single-page application (SPA) designed to provide users with a straightforward and efficient way to manage their personal tasks. The application will not include any sharing functionalities, emphasizing a clutter-free and focused user experience. The app is intended for personal use, allowing users to create, edit, and delete tasks seamlessly.

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 edit existing tasks.
• As a User, I should be able to delete tasks from my list.
• As a User, I should be able to mark tasks as completed.
• As a User, I should be able to view all tasks in a single-page layout.

User Personas

• User: An individual looking for a simple and efficient way to manage personal tasks without the need for sharing or collaboration features.

Visuals Colors and Theme

• primary: #4A90E2 (a calming blue)
• primary_light: #A6C8F0 (a lighter tint of the primary blue)
• secondary: #F5A623 (a warm amber for emphasis)
• accent: #E94E77 (a vibrant pink for CTAs and active states)
• highlight: #F8E71C (a bright yellow for notifications and hover states)
• bg: #F7F9FC (a soft, light background color)
• surface: rgba(255, 255, 255, 0.9) (a subtle white for card backgrounds)
• text: #333333 (a dark grey for primary text)
• text_muted: #888888 (a softer grey for secondary text)
• border: rgba(200, 200, 200, 0.5) (a light grey for borders)

Signature Design Concept

The mellow-webapp will feature an interactive "Zen Garden" homepage. As users scroll through their tasks, the background will subtly animate with calming, flowing water and gentle swaying bamboo. This creates a serene environment that enhances focus and relaxation. The garden elements will respond to user interactions: hovering over tasks will cause ripples in the water, and clicking on tasks will make bamboo leaves rustle gently. This concept will be implemented using framer-motion for smooth animations and gsap for scroll-triggered effects.

Interaction Model & Motion Direction

The landing page will utilize a "parallax" interaction model. Layers of the Zen Garden will move at different speeds as the user scrolls, creating a sense of depth and immersion. Task elements will have animated reveals and hover transitions to maintain a polished and engaging user experience. Internal pages will adopt a "static" model to prioritize readability and task management efficiency.

Non-Functional Requirements

• The application must load quickly and perform efficiently on all modern web browsers.
• The design should be responsive and accessible, ensuring usability across various devices and screen sizes.
• The application should maintain a high level of security to protect user data.

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 will be used primarily for personal task management.
• The design will focus on simplicity and minimalism, avoiding complex features like task sharing or collaboration.
• The application will be developed to support English as the primary language.
