title: What is the proper way to do seed mongoDB in NestJS, using mongoose and taking advantage of my already defined schmas
body: <p>We are using NestJS with mongoose and want to seed mongoDB.
  Wondering what is the proper way to seed the database, and use the db schemas already defined to ensure the data seeded is valid and properly maintained.</p>
  
  <p>Seeding at the module level (just before the definition of the Module) feels hacky and ends in threadpool being destroyed, and therefore all following mongo operations fail</p>
