How shreyas-sv1/local-shop-ordering-billing-system works

This is a React grocery-ordering application backed by an Express REST API and MySQL. Customers sign in, browse and search products, manage a cart, submit an order, and view order history or bills; admins manage products and orders, review dashboard statistics, and generate bills. The graph follows the documented product workflow and the sampled routing/controller code. Several frontend pages and the database connection are represented by their tree paths, but their implementation details were not sampled, so uncertain internal calls are omitted.

Main entry points: api.js HTTP API client · App.js React app and routes · Home.js Product browsing · AdminPanel.js Admin panel
