TaoBao System Requirements Document

1. Introduction

This document outlines the system requirements for the TaoBao project, a web-based version of the popular e-commerce platform. The initial phase focuses on developing a portion of the platform, excluding the purchasing functionality. The document will detail the system overview, functional requirements, user personas, core user flows, visual design, and other relevant sections to guide the development process.

2. System Overview

The TaoBao project aims to create a web version of the TaoBao platform, initially focusing on browsing and exploring products without the purchasing capability. The system will support user interactions such as searching for products, viewing product details, and navigating through categories. The platform will be designed to accommodate future enhancements, including purchasing functionalities.

3. Functional Requirements

• As a User, I should be able to search for products using keywords.
• As a User, I should be able to view product details, including images, descriptions, and specifications.
• As a User, I should be able to navigate through product categories.
• As a User, I should be able to view recommended products based on browsing history.
• As a User, I should be able to use the "继续" command to continue previous actions seamlessly.

4. User Personas

• Regular User: Individuals who browse the TaoBao platform to explore products and gather information.
• Guest User: Visitors who access the platform without logging in, primarily for browsing purposes.

5. Core User Flows

• Regular User searches for a product -> views product details -> navigates through categories -> views recommended products.
• Guest User accesses the homepage -> searches for a product -> views product details.

6. Visuals Colors and Theme

• primary: #FF4500 (a vibrant orange reflecting the brand's energy)
• primary_light: #FFA07A (a lighter tint of the primary color for hover states)
• secondary: #4682B4 (a steel blue for headlines and emphasis)
• accent: #32CD32 (a lime green for CTAs and active states)
• highlight: #FFD700 (a gold color for hover states and notifications)
• bg: #FFFFFF (a clean white background)
• surface: rgba(245, 245, 245, 0.8) (a light grey for card backgrounds)
• text: #333333 (a dark grey for primary text)
• text_muted: #777777 (a softer grey for secondary text)
• border: rgba(200, 200, 200, 0.5) (a subtle grey for borders)

7. Signature Design Concept

The TaoBao homepage will feature an interactive "Product Carousel" concept. Users will be greeted with a 3D carousel of featured products that they can rotate and explore. Each product card will flip to reveal details when clicked, providing an engaging and dynamic browsing experience. The carousel will be implemented using @react-three/fiber for 3D rendering and framer-motion for smooth animations. This concept will create an immersive first impression, encouraging users to interact with the platform.

8. Interaction Model & Motion Direction

The landing page will utilize a "parallax" interaction model, providing a layered depth effect as users scroll through the page. Decorative elements will move at different speeds, creating a visually rich experience. Internal pages will maintain a "static" interaction model to ensure clarity and ease of navigation.

9. Non-Functional Requirements

• The system should be scalable to accommodate future enhancements, including purchasing functionalities.
• The platform must ensure fast loading times and responsive design across various devices and screen sizes.
• The system should support localization for the Japanese market, including language and currency settings.

10. Tech Stack

• Frontend: React for Web
• Backend: Python, FastAPI
• Database: MySQL or MariaDB, using Alembic for migrations
• Local Orchestration: Docker, docker-compose
• Server-side Orchestration: Kubernetes

11. Assumptions and Constraints

• The initial phase will not include purchasing functionalities.
• The platform will be developed with scalability in mind to support future enhancements.
• Localization will be focused on the Japanese market.

12. Glossary

• TaoBao: A popular e-commerce platform in China.
• 3D Carousel: An interactive element that allows users to explore products in a three-dimensional space.
• Parallax: A design technique where background images move slower than foreground images, creating a sense of depth.
• Localization: Adapting the platform to meet the language and cultural preferences of a specific region.

This document serves as a comprehensive guide for the development of the TaoBao web platform, ensuring alignment with user expectations and project goals.
