## Overview

HostelBite Server is a REST backend for hostel meal management. A user or administrator calls the Express API; authenticated routes verify Firebase tokens and role-protected routes check administrator access. The API supports meal discovery, requests and serving, reviews, packages, user roles, dashboards, and payment intents. Route handlers query or update MongoDB collections, while payment-intent creation calls Stripe. The README documents Firebase authentication and analytics; sampled route excerpts show some, but not all, implementations, so uncertain internal wiring is omitted.

Main entry points: [`index.js`](https://github.com/samiul821/hostelbite-server/blob/main/index.js) (Express REST API)
