- Sketch of a Post-ORM
- I want to move to Scala 3, but I'm not sure what libraries to use
-
Ask HN: What cutting-edge technology do you use?
I'm using it mostly for full-stack web development with ScalaJS (https://www.scala-js.org) in the frontend (https://outwatch.github.io/docs/readme.html) and in the backend with AWS lambdas.
The ecosystem is currently in the process of porting all the libraries to Scala 3. So if you're new to Scala, I'd recommend to start with Scala 2, which is rock-solid and already very powerful.
I never worked with SQLAlchemy. But on the scala database side, popular libraries are Doobie (https://tpolecat.github.io/doobie) and Quill (https://getquill.io). Keep in mind that these are for Scala on the JVM. On the ScalaJS side I'm using the javascript library pg. But I'd like to try if it works well with Prisma soon.
The nice thing about ScalaJS is, that you can use Javascript libraries. And if there are typescript facades, then you can transpile these to Scala and use them in a type safe way (https://scalablytyped.org).

Fp libraries that target scala 3 exclusively?
I know that libraries like Scodec and shapeless were rewritten practically from scratch for Scala 3, taking advantage of the next syntax and internals, as well as protoquill - a Scala 3 implementation of Quill.
-
Best Scala framework / libraries out there ?
Akka HTTP, Cats, Quill, ninny, Monix Observable, mill.
-
Ideas for a Scala 3 MapStruct library?
https://getquill.io/#docs (Look under SCHEMA).

Ask HN: What stack would you use to build a CRUD web app on the JVM today?
I would use it at work because I know it. There are a LOT of libraries in Scala for HTTP up to database stuff, and it really depends on what kind of ecosystem you're walking into:
* Scala as Python: https://github.com/com-lihaoyi/cask, maybe https://github.com/getquill/quill
* Scala as Haskell: HTTP4s, https://tpolecat.github.io/doobie/
* Scala as Rails: Play
Play is the closest thing to Rails-like CRUD productivity IMO, and honestly for CRUD most times I would like to write as little code as possible and just get it done, even using low/no-code solutions (postgrest, hasura, htmx), but that wasn't the question :)

[Debate] Is type level programming useful?
quill is uses type level programming. It allows for the pre-computation of SQL queries during compilation, and you can inspect what queries will look like, whilst you code without, running anything.
-
From First Principles: Why Scala?
I've heard that too but I think there are at least efforts to support Scala 3.
Having said that I think Quill looks nicer (https://getquill.io/) if you want a DSL like that.
Slick
- How many people/companies are fully on Scala 3?
-
First Slick prerelease for Scala 3!
Made a PR on slick to document this https://github.com/slick/slick/pull/2760 (workaround is quite easy, you can just define def tupled = (apply _).tupled in the companion object of the case class and it will also compile for all Scala versions).
-
Sketch of a Post-ORM
The Scala ecosystem has a few ways to do composable type-safe query building, e.g. Slick[0] or more recently Quill[1]. . I believe both also have ways to do compile-time string interpolation (e.g. sql"""select * from users where id = ${user.id}""") which generate prepared statements (I know Slick does prepared statements. Quill has similar macros but I haven't looked into how safe they are to use).
-
Database abstraction library which allows a clean domain model
With all this in mind, I landed at the first candidate: slick from https://scala-slick.org/ that you all probably know.
-
Scala 3 migration: 7 benefits that outweigh the risks
I think Slick's current priority is also getting in Scala 3 support: https://github.com/slick/slick/issues/2177
-
Slick 3.4.x is here!
Future releases might not be announced here. To get notified, go to https://github.com/slick/slick, click the Watch dropdown button at the top, select Custom, check Releases, and click Apply.
-
Is there any good resource for learning Slick (3.x)?
https://github.com/slick/slick/pull/2097 now I use slightly lower version of slick so this might be an upgrade that resolves (I do recall using it in 21 and it was still buggy and I filed a ticket, which I cannot find at the moment), but given a complex enough query (we have one in PROD which has tons of flexibility in terms of filters that can be passed in) but it also makes for complex code.
-
Slick 3.4.0 is imminent
I started writing a reply but then I realized it would be long and depends on exactly what you mean, so maybe it's better to post the question in https://github.com/slick/slick/discussions/categories/questions?
You can see the draft release notes here and the upgrade guide at https://scala-slick.org/doc/prerelease/upgrade.html#upgrade-from-3-3-x-to-3-4-0. The latest docs are at https://scala-slick.org/doc/prerelease/index.html.
