System Requirements Document (SRD) for garnet-application

1. Introduction

The garnet-application is a mobile application designed to provide a simple and intuitive user experience for cross-platform usage on iOS and Android. This document outlines the system requirements for the garnet-application, including functional and non-functional requirements, user personas, design concepts, and technical specifications. The application will initially focus on basic functionality such as login and logout, with predefined credentials.

2. System Overview

The garnet-application is a React Native-based mobile application aimed at delivering a seamless "Hello World" experience with added login and logout functionality. The application will cater to administrators with predefined credentials for authentication. The app will be lightweight, user-friendly, and optimized for both iOS and Android platforms.

Key features include:

• Cross-platform compatibility (iOS and Android).
• Simple login and logout functionality.
• Predefined admin credentials for authentication.

3. Functional Requirements

• As Admin, I should be able to log in using the username "admin" and password "admin".
• As Admin, I should be able to log out of the application.
• As Admin, I should see a "Hello World" message upon successful login.

4. User Personas

Admin

• Description: The primary user of the garnet-application. Responsible for accessing the application using predefined credentials.
• Goals:
  • Authenticate using the provided username and password.
  • Access the "Hello World" message upon successful login.
  • Log out securely when finished.
• Pain Points:
  • Requires a simple and straightforward authentication process.
  • Needs a responsive and intuitive interface.

5. Visuals Colors and Theme

The garnet-application will adopt a clean and modern design aesthetic with the following color scheme:

• Primary Color: Garnet Red (#8B0000) – representing the application's name and providing a bold, distinctive look.
• Secondary Color: White (#FFFFFF) – for clean backgrounds and text contrast.
• Accent Color: Light Gray (#D3D3D3) – for borders, buttons, and inactive states.
• Font: Use a sans-serif font like "Roboto" or "Open Sans" for readability.

The theme will emphasize simplicity and clarity, ensuring a user-friendly experience.

6. Signature Design Concept

Interactive Garnet Crystal Animation

The home page of the garnet-application will feature a bold and unforgettable design: a rotating 3D garnet crystal at the center of the screen. This crystal will serve as both a visual centerpiece and an interactive element.

• Animation: The garnet crystal will slowly rotate on its axis, reflecting light dynamically as the user moves their device (using gyroscope/accelerometer data). Subtle sparkles will emanate from the crystal, creating a mesmerizing effect.
• Interaction: Upon successful login, the crystal will "shatter" into smaller pieces, revealing the "Hello World" message in a glowing, garnet-red font. When the user logs out, the crystal will reassemble itself with a smooth animation.
• Transitions: The background will shift from a neutral light gray to a deep garnet gradient during login, enhancing the immersive experience.
• Micro-interactions: Buttons will have a ripple effect when tapped, and the logout button will feature a "fade-out" animation for the crystal.

This design concept ensures that the garnet-application leaves a lasting impression on users while maintaining functionality.

7. Non-Functional Requirements

• The application must load within 2 seconds on both iOS and Android devices.
• The login and logout processes must complete within 1 second.
• The application must function offline for the "Hello World" display but requires an internet connection for backend authentication.
• The app must support iOS 14+ and Android 8.0+.
• The UI must be responsive and adapt to various screen sizes.

8. Tech Stack

Frontend

• React Native for mobile app development.

Backend

• Python with FastAPI for handling authentication requests.

Database

• MySQL for storing admin credentials and managing user sessions.
• Alembic for database migrations.

AI Tools

• Not applicable for this version.

Local Orchestration

• Docker for containerization.
• docker-compose for managing multi-container applications.

Server-Side Orchestration

• Kubernetes for deployment and scaling.

9. Assumptions and Constraints

Assumptions

• The application will only have one user type (Admin) for this version.
• The admin credentials (username: "admin", password: "admin") are predefined and stored securely in the backend.
• The application will not include advanced security measures (e.g., two-factor authentication) in this version.

Constraints

• The application must be lightweight and optimized for low-end devices.
• The backend must be hosted on a server with minimal latency for Indian users.
• The design must adhere to the specified garnet-themed color scheme.

10. Glossary
