System Requirements Document (SRD)

Project Name: onyx-weather

1. Introduction

The onyx-weather application is a modern weather web platform designed to provide real-time weather data, forecasts, interactive maps, and weather-related news. Developed for users in India, the application leverages OpenWeatherMap API for dynamic weather updates and integrates MySQL for storing historical weather data and analytics. This document outlines the system requirements for the development of the application, ensuring it meets the needs of visitors, registered users, and administrators.

The application aims to deliver an intuitive and engaging user experience while maintaining robust functionality for weather tracking, forecasting, and content management.

2. System Overview

The onyx-weather application will feature three primary user roles:

1. Visitor: Can view weather data and news without registration.
2. User: Can access advanced features such as forecasts, interactive maps, and personalized settings after registration.
3. Admin: Responsible for managing permanent weather data, blog/news content, and overseeing system operations.

The application will include the following core pages:

• Homepage: Overview of current weather and featured news.
• Current Weather Page: Detailed weather conditions.
• Forecast Page: Short-term and long-term weather forecasts.
• Maps Page: Interactive weather maps with radar and satellite imagery.
• News/Blog Page: Latest weather news and alerts.
• About Page: Information about the app.
• Settings Page: User preferences and notification settings.
• Registration and Login Pages: Secure user authentication.

The system will integrate OpenWeatherMap API for real-time weather data and store API responses in a MySQL database for historical tracking and analytics.

4. User Personas

Visitor

• Description: Unregistered users who can view basic weather data and news.
• Goals: Access weather information quickly without registration.
• Pain Points: Limited access to advanced features.

User

• Description: Registered users who can access personalized features, forecasts, and settings.
• Goals: Get detailed and customized weather updates.
• Pain Points: Need for seamless registration and login processes.

Admin

• Description: System administrators who manage weather data, news content, and user accounts.
• Goals: Ensure data accuracy and system reliability.
• Pain Points: Efficient tools for managing large datasets and content.

5. Visuals Colors and Theme

Color Palette

• Background: #F0F8FF (Alice Blue)
• Surface: #FFFFFF (Pure White)
• Text: #333333 (Charcoal Black)
• Accent: #0078D7 (Azure Blue)
• Muted Tones: #B0C4DE (Light Steel Blue)

The theme reflects a clean and modern aesthetic, emphasizing clarity and accessibility. The colors are inspired by the sky and weather elements, creating a calming and professional atmosphere.

6. Signature Design Concept

Concept: Interactive Weather Globe

The homepage will feature a 3D interactive weather globe that users can rotate and zoom into. The globe will display real-time weather conditions for different regions, with animated weather icons (e.g., clouds, rain, sun) overlaying the globe. Users can click on a region to view detailed weather data for that location.

Details:

• Animations: Smooth globe rotation and zoom transitions.
• Interactions: Hovering over a region displays a tooltip with temperature and conditions.
• Color Shifts: The globe's background changes dynamically based on the time of day (e.g., sunrise, daylight, sunset).
• Micro-Interactions: Clicking a region opens a modal with detailed weather data and forecast.

This bold design will make the homepage visually stunning and instantly engaging, setting the tone for the rest of the application.

7. Non-Functional Requirements

• Performance: The system should load pages within 3 seconds under normal conditions.
• Scalability: Support up to 10,000 concurrent users.
• Security: Implement secure authentication and data encryption.
• Reliability: Ensure 99.9% uptime for the application.
• Localization: Default settings optimized for Indian users (e.g., IST timezone, Celsius units).

8. Tech Stack

• React for Web

Backend

• Python
• FastAPI

Database

• MySQL (with Alembic for migrations)

AI Models
