This is totally off topic, but I am glad to see this here. Nest.js seems really powerful on the surface, when you start reading their docs [0] everything makes sense at first. But the deeper you go, the more it sets in that the complexity introduced by its "magic" results in very little being easily reasoned about. Just look at the process for building a GraphQL API [1], for example, it starts out simply enough then goes off the deep end. Decorators, dependency injection and providers within providers all the way down.
