First Time working with Node (Express)

Type: Node (Express)

This was my first project using Node and Express to develop a backend.
Project of an online bookshelf, where it is possible to register books and authors.
Backend made in Node (Express)
Frontend made using EJS templates
MongoDB database
Despite the simplicity of the project, I could understand well how creating a backend with Node, how MongoDB works, how non-relational databases work in general, how the EJS template engine works, hosting with heroku
I was able to host this project on herokuapp, but it may not be working anymore, due to the time it was made and the lack of maintenance and MongoDB activation
