## Overview

Hotel Booking App serves guests browsing properties and making date-based reservations, while owners manage listings and confirm bookings. The main flow runs from listing routes and controllers through listing data and views, then into booking validation, availability checks, persistence, and reservation views. Reviews and account access are separate user-facing branches; listing maps provide a location view. The README documents OAuth, contact details, and other capabilities not fully represented in the sampled source, so those subsystem links are shown only where supported.

Main entry points: [`app.js`](https://github.com/roydhirj19/project/blob/main/app.js) (Express application), [`controller/booking.js`](https://github.com/roydhirj19/project/blob/main/controller/booking.js) (Booking controller), [`controller/listing.js`](https://github.com/roydhirj19/project/blob/main/controller/listing.js) (Listing controller), [`controller/reviews.js`](https://github.com/roydhirj19/project/blob/main/controller/reviews.js) (Review controller)
