nestjs-auth VS MikroORM

So I spent a lot of time in the Nest ecosystem, and I wrote some nontrivial libraries with a little (not a lot) of uptake (and neither are actively maintained at this point, so these are here mostly for completeness):

I was pretty excited by NestJS when I ran into it because, well--I don't mind magic, when it's done right. I quite like Spring Boot, for example. But NestJS's magic is...incorrect, in a lot of ways. The DI container is a little bit scary, with oddly hardcoded ways to register interceptors into request scope (itself necessary because NestJS's logging facilities aren't--or weren't at the time--decorating requests with X-Request-Id or similar, so you had to register your own) and no way to then define interceptor order.

It also has a lot of really overlapping nouns; guards are interceptors but less capable (and @eropple/nestjs-auth didn't use them at all) and the "pipe" concept for validation was itself inscrutable. To make it usable, I ended up just doing everything with decorators and interceptors, all living in request scope. And once I'd gotten it going, it was pretty nice. But it also meant broad incompatibilities with much of the NestJS ecosystem.

In my usual NodeJS tech stack, which includes GraphQL, NestJS, SQL (predominantly PostgreSQL with MikroORM), I encountered these limitations. To overcome them, I've developed a new stack utilizing Rust, which still offers some ease of development:

Mikro-ORM is a TypeScript ORM that focuses on simplicity and efficiency. It supports various SQL databases and MongoDB. Mikro-ORM is known for its simplicity and developer-friendly APIs. It provides a concise syntax for defining data models and relationships, making it easy to use.

I found MikroORM [0] to be quite reasonable if you're in the TS ecosystem already. It was also easy to do custom, raw queries, and really just felt like it wasn't in the way.

It also does code generation into its own module, so good luck with hoisting in a monorepo where you want multiple independent prisma schemas. MikroORM[1] is a much better alternative to Prisma in my opinion but any ORM carries some form of baggage.
