Would that be a "RRM" (Record-Relational mapper)? If so we're already on board (in a different language).

P.S. I bet you would never guess which typed language with great support for records makes it easy (for the most part) to build most type-safe SQL queries on the fly, even with projections, without explicitly defining types for every possible projection variation.

Lots of Python codebases are on board with that (and I assume codebases in other languages are as well). It's by convention rather than language-level support, but works perfectly well: don't bolt business logic onto your ORM classes' methods, handle those elsewhere in a separate layer whose conventions you define. Works great.

I get that you're talking about Typescript, but I just want to say that Scala excels in this area as well. I found Slick to be a pleasure to work with once I embraced not trying to map directly from a relational model to an object model, but instead to just use Scala's ability to manipulate and reshape the relational model as needed.

I've come to appreciate that model, too.

Somewhere in one of his talks, Rich Hickey goes on this great mini-rant about, "Why can't we just let data be data?" I wish I could remember exactly which one it is. Maybe "Simple Made Easy"?

Any TypeScript libraries you are using?

We used https://github.com/brianc/node-sql but it unfortunately stopped being maintained, so now we maintain our own fork.

Would you happen to be talking about TypeScript?

yes
