This isn’t a corporate project it’s just a 2nd year messing around

Overview

I am building a multi-store, single-user e-commerce web app, similar to Amazon. In this system, multiple stores can participate and sell their products to a single user. I am using the MERN stack with TypeScript for development. Below are my current backend and frontend structures:

Backend Directory Structure

Frontend Directory Structure

App.tsx
index.css
main.tsx
vite-env.d.ts
├───assets
├───components
│       (Reusable components like NavBar, Footer, CartComponent, etc.)
├───context
│       ShopContext.tsx
├───Hooks

Current Goals

1. Add functionality for product and order management.
2. Make the system modular and robust to support upcoming AI-powered agentic workflows within 3-5 days.
3. Consider whether to integrate an admin panel for managing stores, products, and orders.

Questions

1. How can I improve the current backend structure to make it more modular and maintainable, particularly for product and order management?
2. Should I integrate an admin panel for managing stores, products, and orders? If yes, how should it fit into the existing architecture?
3. What design principles or patterns should I follow to seamlessly integrate AI workflows (like recommendations, order predictions) into this architecture?

Expected Insights

• Suggestions on modularizing the backend for scalability and maintainability.
• The role and integration of an admin panel in a multi-store e-commerce setup.
• Design patterns or practices for future AI feature integrations.
• Recommendations for improving both backend and frontend design to handle product and order management effectively.
