Thanks for sharing!

I was wondering how to apply database migrations with Mongoose in a NestJS template but I figure out that I was trying to implement a Database seeding instead because you don't need migrations with a NoSQL Database. This is my template: github.com/proyecto26/MyAPI/tree/n...

In production database you might need to apply migration on existing data even in document oriented database.
For example: you can clean some legacy data. (GDPR compliance for example)
Seeding is only for new data or starting a new environment.
