I created this web based in Fazt tutorial: node-js & mongodb CRUD.
Making this, I learned the basics about MVC, Express, Nodejs, MongoDB, Mongoose.js, Handlebars, environment variables and some of the dependences that this CRUD needed to be deployed on HEROKU. For the styling part I copied the entire modeling. I wanted to learn about backend.
You can access and test the CRUD here: https://tasks-app-agrigaliunas.herokuapp.com/
