- 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.

Database abstraction library which allows a clean domain model
Using Circe so I define some classes that contain my custom Encoder[BusinessObject] in a file and I use that whenever I want to save/store a record, or handle a web request or respose. I also represent my mongo queries as JSON objects that I can freely build then pass to the driver.

What companies/startups are using Scala (open source projects on github)?
Circe adopters should be using Scala https://github.com/circe/circe
-
what popular companies uses Scala?
If you look at Circe's github repo you will see a very large list of very recognizable companies, that should give you some idea. Circe isn't the ONLY Json parsing library, but it is probably the most popular, so - should give you a rough idea of the types and variety of companies using Scala.

Every time I sit down to use an HTTP client and JSON parser, I get really frustrated
Has the worst error messages I've ever seen for a parser. "Attempt to decode value on failed cursor" is not helpful when all you have is missing fields. Has been an issue for 5 years.
-
It's unsafe to depend on Typelevel Libraries
Circe tries to drop Scala 2.12 support in retaliation for not enough users paying them.

[Circe] Renaming fields for value classes during decoding
PR for the same functionality in Scala3: https://github.com/circe/circe/pull/1800

Scala 3.0 serialization
Otherwise I tend to just use ZIO-JSON or Circe both of which have been updated for Scala 3.

Performance of 12 JSON parsers for Scala
I've updated results of benchmarks of 12 JSON parsers for Scala: - AVSystem's scala-commons - Borer - Circe - DSL-JSON - Jackson - jsoniter-scala - Play-JSON, - play-json-jsoniter - Spray-JSON - uPickle - weePickle - zio-json
What are some alternatives?
doobie - Functional JDBC layer for Scala.
json4s - JSON library
spray-json - A lightweight, clean and simple JSON implementation in Scala
Quill - Compile-time Language Integrated Queries for Scala
ScalikeJDBC - A tidy SQL-based DB access library for Scala developers. This library naturally wraps JDBC APIs and provides you easy-to-use APIs.
play-json
zio-json - Fast, secure JSON library with tight ZIO integration.
jackson-module-scala - Add-on module for Jackson (https://github.com/FasterXML/jackson) to support Scala-specific datatypes
jsoniter-scala - Scala macros for compile-time generation of safe and ultra-fast JSON codecs
argonaut - Purely functional JSON parser and library in scala.
Squeryl - A Scala DSL for talking with databases with minimum verbosity and maximum type safety
