Demo on Vercel:

https://nodejs-mongodb-gamma.vercel.app/

Usage

• git clone https://github.com/smohadjer/nodejs-mongodb.git
• If you don't have a Mongodb database follow instructions at https://stackabuse.com/integrating-mongodb-with-node-js/ to create a free Mongodb database in the cloud. If you give access to database from any IP (using ip 0.0.0.0/0) then you don't need to integrate MongoDB with Vercel.
• create a .env file in root and add db_username and db_password for your Mongodb database. The path to database is in file /api/db.js and you can change it if needed.
• Run npm install at root of project
• Run npm start and then go to: http://localhost:8000/list.html
• or alternatively run vercel dev and then go to: http://localhost:3000/list.html

npm start executes server.js in root of project which then starts an express server. If you have Vercel cli installed, you don't need to use server.js and can simply run the project using vercel dev command.
