Thanks for pointing out! I saw pgtyped-rescript when I was looking around. TBH, I was confused by it a little because I have no if the SQL parser works properly not only for simple CRUD-requests, but for multi-level-nested monsters with JOINs after JOINs and WITH sub-queries on top of it. From my practical experience (in TypeScript) I see that Postgres.js can handle this because it is dumb and straightforward. I decided not to take the risk with pgtyped at this point.
However, it looks promising. In perspective, the approach with code generation can indeed fit ReScript better than anything else. I’m really looking forward at its development.
