Overview

This server performs crud operations on a listings collections and images collections. Certain routes can require authentication and authorization priveleges.

Architecture

• The server uses an express framework and is deployed through heroku.
• MongoDB is used to store listings information and image urls.
• Actual images are not stored in our database, but a middleware in the image route, sends images to Cloudinary, and saves the url to our database.
• Passwords are not stored in our database but handled through Auth0 on the frontend application.
