nova-marketplace System Requirements Document

1. Introduction

The nova-marketplace is a full-stack vehicle wrecker parts marketplace designed to streamline the process of finding and purchasing vehicle parts. Unlike traditional eCommerce stores, this platform treats vehicles as inventory containers, allowing users to search for vehicles and then find parts linked to those vehicles. This document outlines the system requirements for the nova-marketplace, ensuring a comprehensive launch with all features included.

2. System Overview

The nova-marketplace is designed to serve both public users and administrators. Public users can search for parts, browse vehicles, and request quotes or purchase parts. Administrators have the ability to manage inventory, including adding and editing vehicles and parts, and viewing orders. The system supports multi-location inventory management, advanced search capabilities, and optional payment integration.

3. Functional Requirements

• As a Public User, I should be able to view available vehicles in the yard.
• As a Public User, I should be able to find parts linked to those vehicles.
• As a Public User, I should be able to request quotes or buy parts.
• As an Admin, I should be able to add/edit vehicles.
• As an Admin, I should be able to add/edit parts.

6. Signature Design Concept

The homepage of nova-marketplace will feature an interactive 3D garage environment where users can explore vehicles as if they are walking through a real yard. Using @react-three/fiber and @react-three/drei, users can click on vehicles to open detailed views, revealing parts available for purchase. As users hover over vehicles, subtle animations highlight parts that are in stock. The environment will dynamically adjust lighting and shadows to create a realistic and immersive experience. This interactive model not only enhances user engagement but also provides a unique way to visualize inventory.

7. Interaction Model & Motion Direction

The landing page will utilize a "parallax" interaction model, creating a layered depth effect as users scroll. Decorative elements such as atmospheric lighting and vehicle silhouettes will move at different speeds, while the main content remains in the natural flow. This approach is ideal for creating a visually rich first impression. Internal pages like the admin dashboard and settings will adopt a "static" model for clarity and efficiency.

8. Non-Functional Requirements

• Secure authentication using JWT.
• Input validation to prevent errors and ensure data integrity.
• Protection against XSS/CSRF attacks.
• Scalable search capabilities, potentially using Elasticsearch.
• Pagination for handling large datasets efficiently.

9. Tech Stack

• Frontend: React for Web
• Backend: Python, FastAPI
• Database: MySQL or MariaDB, using alembic for migrations
• Image Upload: Cloudinary or S3
• Search: Elasticsearch (if possible)
• Authentication: JWT
• Optional Payments: Stripe integration

10. Assumptions and Constraints

• The system will support multi-location inventory management.
• The platform must be optimized for large inventories.
• The design will be mobile responsive to cater to a wide range of devices.
• The system should be scalable to accommodate future growth.

11. Glossary

• JWT: JSON Web Token, a compact, URL-safe means of representing claims to be transferred between two parties.
• XSS: Cross-Site Scripting, a security vulnerability typically found in web applications.
• CSRF: Cross-Site Request Forgery, a type of malicious exploit of a website.
• Elasticsearch: A distributed, RESTful search and analytics engine capable of addressing a growing number of use cases.
