## Overview

This is a server-rendered hostel allotment and mess-management application. Students register or sign in, request or vacate rooms, raise and track requests, view menus, and submit meal feedback; wardens manage blocks, rooms, residents, requests, menus, and feedback. Express routers dispatch to controllers, which apply role checks and use Mongoose models for persisted state. The README documents capabilities beyond the sampled excerpts; those are represented at the subsystem level, while uncertain controller-to-model details are not expanded. The graph omits deployment and setup machinery.

Main entry points: [`controllers/adminController.js`](https://github.com/kiransinha872/hostelandmessmanagementsystem/blob/main/controllers/adminController.js) (Warden operations), [`controllers/studentController.js`](https://github.com/kiransinha872/hostelandmessmanagementsystem/blob/main/controllers/studentController.js) (Student portal), [`server.js`](https://github.com/kiransinha872/hostelandmessmanagementsystem/blob/main/server.js) (Web application), [`models/User.js`](https://github.com/kiransinha872/hostelandmessmanagementsystem/blob/main/models/User.js) (User records)
