## Overview

This is a product-management storefront: customers can browse products, authenticate, and place orders; administrators manage products and order status. The backend routes requests to controllers, which query SQLite, while startup initializes and seeds the database before listening. The frontend entry point and product service are represented, but their excerpts do not show how they connect to the API, so that relationship is left unasserted. The README is empty; frontend capabilities and integrations beyond the sampled server code remain uncertain.

Main entry points: [`server/src/index.ts`](https://github.com/trafalawgf-wgf/product-management/blob/main/server/src/index.ts) (Express Server), [`server/src/models/db.ts`](https://github.com/trafalawgf-wgf/product-management/blob/main/server/src/models/db.ts) (SQLite Database), [`client/src/main.ts`](https://github.com/trafalawgf-wgf/product-management/blob/main/client/src/main.ts) (Storefront UI), [`server/src/routes/authRoutes.ts`](https://github.com/trafalawgf-wgf/product-management/blob/main/server/src/routes/authRoutes.ts) (Auth Routes)
