Show HN: I open-sourced the in-memory PostgreSQL I built at work for E2E tests
I've used pgmem https://github.com/oguimbal/pg-mem for the last couple of years for the same thing.

Ask HN: How do you test SQL?
I was wondering the other day how to classify tests that use a test double like pg-mem, which isn't a mock but isn't the Dockerized test DB either :

How to test nestjs modules?
In my case, I use TypeORM with PostgreSQL, and there's pg-mem to run an instance in memory, it supports most of the common functionality of PostgreSQL but you will need to do some adjustment to your code to be within the limits.

Working with offline data
Postgres in the browser is possible through pg-mem: "pg-mem is an experimental in-memory emulation of a postgres database" but it also suffers from no persistence. If you can persist to a file somewhere then read it in on startup (and if your local data isn't huge) this might work.

Haskell as a first timer - Am I missing something ? Or is something broken ?
Dont get me wrong: I am trying to contribute to opensource as well, so I get that supporting small projects can be demanding. There's nothing wrong in not spending your weekends on OS. But not asking for help, nor specifying that a project is unmaintained, nor even answering issues & pull requests for years feels just wrong.

Ask HN: What Are You Working On?

pg-mem, an in memory postgres DB instance for your unit tests, is now bound to multiple libraries (Knex, Typeorm, Slonik, pg, pg-promise) ... suggestions for the next one ?
Okay, I had a bit of spare time,I've implemented that, and it is now available with [email protected]

Zero delay development & unit testing iterations
To get a glimpse of what I'm talking about, you can clone this repo and follow "Development" instructions (by the way this is a small OS lib I maintain, I wrote about it here)

Which ORM would you pick, Prisma or Typeorm
As few comments have already offered alternatives, so I'll mention Joist.
-
Does Typeorm violate the type contract when using relations that aren't explicitly loaded?
I used TypeORM in the past; I had a ton of problems with it. I highly recommend https://joist-orm.io/ instead.
-
What is your favorite way to maintain types and schema in a full stack web app, end-to-end?
Codegen our backend models directly from the db (here a strict 1-1 mapping is a feature imo; we use https://github.com/stephenh/joist-ts/), so we get `Green` added to the backend `Color.ts` for free.

Well, shit. Objection.js has been sunset, which ORM/querybuilder did you move to?
Ha, well, as you noted, I'm wary of even bothering to comment :-), but would be great if you checked out Joist: https://joist-orm.io/
