pg-mem
- Setting up PostgreSQL for running integration tests

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?
A pure Javascript in memory emulation of Posgres, to help writing better node tests https://github.com/oguimbal/pg-mem
-
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)
What are some alternatives?
kv-connect-kit - Minimal Typescript client implementing the KV Connect protocol. Access Deno KV remotely from any Javascript environment like Node, Cloudflare Workers, Bun, Deno, and the browser.
NeDB - The JavaScript Database, for Node.js, nw.js, electron and the browser
kysely - A type-safe typescript SQL query builder
Prisma - Next-generation ORM for Node.js & TypeScript | PostgreSQL, MySQL, MariaDB, SQL Server, SQLite, MongoDB and CockroachDB
denodata - A Deno native indexed database. Backed by the Deno KV store, denodata has zero external dependencies. Both traditional table-oriented and object-oriented index approaches are supported and can be mixed and matched. The standard Deno KV key-value functions remain available and are enhanced to support the indexing and metadata features. Support for automatic serialization and deserialization of class instances, automatic key/value expiration and developer defined metadata. Support for Date, RegExp and symbol as part of keys. Support for symbol as part of values. A powerful db.find function that supports approximate matching and works on both indexes and regular keys with over 50 operators including regular expressions, soundex/echoes, credit card, SSNs and more. If something is missing, it can be added in as little as one line. A subscription API allows listening for changes to the database.
