## Overview

Pizzeria Jetski is a web application with a React frontend and a NestJS backend backed by PostgreSQL. The principal visible workflow is a browser loading the frontend, reaching the router, and opening public or administrative pages. The tree also shows employee and manager page areas, though the sampled router does not connect them. On the server, startup initializes the application and seeds the database when needed; a separate health endpoint checks database connectivity. Backend request/data flows are based on sampled source; broader page capabilities are inferred from filenames and route declarations.

Main entry points: [`frontend/src/app/router/AppRouter.jsx`](https://github.com/georgi-01/pizzeria-jetski-web-app-vms/blob/main/frontend/src/app/router/AppRouter.jsx) (App router), [`backend/src/database-initializer/database-initializer.service.ts`](https://github.com/georgi-01/pizzeria-jetski-web-app-vms/blob/main/backend/src/database-initializer/database-initializer.service.ts) (Database initializer), [`backend/src/app.module.ts`](https://github.com/georgi-01/pizzeria-jetski-web-app-vms/blob/main/backend/src/app.module.ts) (Application module), [`backend/src/prisma/prisma.service.ts`](https://github.com/georgi-01/pizzeria-jetski-web-app-vms/blob/main/backend/src/prisma/prisma.service.ts) (Prisma client)
