the code should connect to our actual db on cloud.mongodb.com i invited yall to. if you go to cluster, then connect, you can find instructions on how to connect to it. make sure you use environment variables and don't put the actual link or password in the repo. its pretty easy, just create a .env file in the server, install the dotenv in there, and follow instructions here for using environment variables https://www.npmjs.com/package/dotenv
