## Overview

Wanderlust is an Express/Mongoose vacation-rental listing app. Visitors browse listings; signed-in users can create, edit, and delete their own listings, upload images, and add or remove reviews. The sampled code shows the app mounting route modules, routes applying authentication/ownership and validation middleware before controllers, and controllers reading or writing MongoDB models and rendering EJS pages. The tree indicates signup/login support; user-route details were not sampled, so those links are limited to the app’s router mount. Image storage is configured separately.

Main entry points: [`app.js`](https://github.com/sanjay-sahoo-0804/project/blob/main/app.js) (Express app), [`routes/listing.js`](https://github.com/sanjay-sahoo-0804/project/blob/main/routes/listing.js) (Listing routes), [`controllers/reviews.js`](https://github.com/sanjay-sahoo-0804/project/blob/main/controllers/reviews.js) (Review controller), [`controllers/listing.js`](https://github.com/sanjay-sahoo-0804/project/blob/main/controllers/listing.js) (Listing controller)
