How do we work in Node without Mongoose?

What we will cover

• What is an ORM?
• Can we live without one?
• How do we structure our code to make it testable?

Notes

Request:

Would you like to go over how'd you design a simple REST API (fp or oop doesn't matter) without using mongoose or an ORM? Just raw SQL with queries. How would you design a service? How would you test it? Cheers
