azure-web System Requirements Document

Introduction

The purpose of this document is to outline the system requirements for the "azure-web" project, which aims to develop a simple web app for a chatbot providing a general chat experience. This document will serve as a guide for the development team to understand the functional and non-functional requirements of the project.

System Overview

The "azure-web" project is designed to create a web application that facilitates a general chat experience through a chatbot interface. The application will be accessible via web browsers and will leverage modern web technologies to ensure a seamless and engaging user experience. The chatbot will be capable of handling a wide range of conversational topics, providing users with an interactive and entertaining platform for casual conversations.

Functional Requirements

• As a User, I should be able to initiate a chat with the chatbot.
• As a User, I should be able to receive responses from the chatbot in real-time.
• As a User, I should be able to view the chat history during the session.
• As a User, I should be able to end the chat session at any time.
• As a User, I should be able to access the chatbot from any web browser.

User Personas

• User: The primary persona for this application, users will engage with the chatbot for casual conversations and general inquiries.

Visuals Colors and Theme

• primary: #4A90E2 (Azure Blue)
• primary_light: #A1C4FD (Light Azure)
• secondary: #FF6F61 (Coral)
• accent: #FFD700 (Gold)
• highlight: #FFA500 (Orange)
• bg: #F5F5F5 (Light Gray)
• surface: rgba(255, 255, 255, 0.9) (White)
• text: #333333 (Dark Gray)
• text_muted: #777777 (Muted Gray)
• border: rgba(0, 0, 0, 0.1) (Subtle Black)

Signature Design Concept

The homepage of the "azure-web" project will feature an interactive galaxy map where each star represents a different conversational topic. Users can click on a star to initiate a chat related to that topic, drag to rotate the galaxy, and hover over stars to see brief descriptions of the topics. This concept will be brought to life using @react-three/fiber for 3D rendering and gsap for smooth animations and transitions. The galaxy will have a dynamic background that subtly changes colors based on the time of day, enhancing the immersive experience.

Interaction Model & Motion Direction

The landing page will employ a "parallax" interaction model, providing a layered depth effect as users scroll. Decorative elements like stars and cosmic dust will move at different speeds, creating a sense of depth and immersion. The main content will scroll naturally, ensuring clarity and ease of navigation. Internal pages will adopt a "static" interaction model to prioritize readability and user efficiency.

Non-Functional Requirements

• The application should be responsive and accessible on all major web browsers.
• The system should handle multiple concurrent users without performance degradation.
• The chatbot should provide responses within 2 seconds to ensure a smooth user experience.
• The application should be designed with scalability in mind to accommodate future enhancements.

Tech Stack

• Frontend: React for Web
• Backend: FastAPI
• Database: MongoDB
• AI Models: GPT 5.4 for user-friendly responses
• AI Tools: Litellm for LLM Routing
• Local Orchestration: Docker, docker-compose
• Server-side Orchestration: Kubernetes

Assumptions and Constraints

• The chatbot will not require authentication for users to initiate a chat.
• The application will be hosted on a cloud platform to ensure scalability and availability.
• The system will not store chat history beyond the session duration for privacy reasons.

Glossary

• Chatbot: A software application used to conduct an online chat conversation via text or text-to-speech.
• Parallax: A scrolling technique used to create an illusion of depth in a 2D scene.
• Responsive Design: An approach to web design that makes web pages render well on a variety of devices and window or screen sizes.
• Scalability: The capability of a system to handle a growing amount of work, or its potential to accommodate growth.
