retro-application System Requirements Document

Introduction

The purpose of this document is to outline the system requirements for the "retro-application," a single-page todo application designed for personal use. This application will focus on minimalistic design principles to ensure a streamlined and efficient user experience.

System Overview

The retro-application is a personal todo application that will be implemented as a single-page web application. The primary goal is to provide users with a simple and intuitive interface to manage their tasks efficiently. The application will be lightweight, focusing on core task management functionalities without unnecessary complexity.

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 my tasks on a single page.

User Personas

• User: An individual looking to manage personal tasks efficiently using a simple and minimalistic interface.

Visuals Colors and Theme

• primary: #2A9D8F (a calming teal)
• primary_light: #A8DADC (a lighter teal for hover states)
• secondary: #E76F51 (a warm coral for emphasis)
• accent: #F4A261 (a vibrant orange for CTAs and active states)
• highlight: #E9C46A (a soft gold for notifications and active indicators)
• bg: #F1FAEE (a light cream background)
• surface: rgba(255, 255, 255, 0.9) (a near-white card background)
• text: #264653 (a deep blue for primary text)
• text_muted: #6D6875 (a muted lavender for secondary text)
• border: rgba(38, 70, 83, 0.2) (a subtle teal border)

Signature Design Concept

The retro-application will feature a retro terminal aesthetic where the content types itself like a hacker console. Users will interact with tasks that appear as lines of code on a vintage CRT monitor interface. The design will include subtle animations where tasks "type" themselves onto the screen, and completed tasks will "fade out" like old text disappearing. The interface will have a green-on-black color scheme reminiscent of early computer screens, with a pixelated font to enhance the retro feel. Users can click on tasks to mark them as complete, and the interface will provide satisfying auditory feedback, such as keyboard clicks and beeps, to enrich the user experience. This concept will be implemented using framer-motion for animations and react-icons for retro-style icons.

Interaction Model & Motion Direction

The interaction model for the retro-application will be "static" to maintain focus on task management efficiency. However, the retro terminal aesthetic will incorporate moderate animations for task interactions, such as typing effects and hover transitions, to add a touch of dynamism without overwhelming the user.

Non-Functional Requirements

• The application must 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 handle up to 100 tasks without performance degradation.

Tech Stack

• Frontend: React for Web
• Backend: Python with FastAPI
• Database: SQLite for simplicity and ease of use in a personal application
• AI Models: Not applicable
• Local Orchestration: Docker for containerization

Assumptions and Constraints

• The application is intended for personal use and will not support multi-user collaboration.
• The design will prioritize simplicity and ease of use over extensive feature sets.
• The application will be developed as a single-page application to ensure a seamless user experience.
