The following two projects are M.E.R.N stack projects.
This means that the tech stack is MongoDB, Express, React and Node JS.
Both the projects follow very similar structure - both in the frontend and the backend.
Files and code are managed with the MVC convention (Model,View,Controller)
Both use MongoDB with Mongoose.
Both the apps are deployed with Netlify for the front end.
Both the apps are deployed with Heroku (Dyno) for the backend end API.
