Question 1

How do I migrate from typesafe config to sconfig?

Accepted Answer

Use the provided scalafix rule by adding sconfig-scalafix to your dependencies and running the command in sbt. It automates package replacement and method adjustments, but ensure to backup your code first as it modifies source files directly.

Question 2

sconfig vs lightbend/config for Scala projects?

Accepted Answer

sconfig is better for multi-platform Scala projects or those using Scala Native/JS, as it's a Scala port with cross-platform support. However, if you're only on JVM and prefer the Java API, lightbend/config might be simpler and more stable.

Question 3

Does sconfig work with Scala 3?

Accepted Answer

Yes, sconfig supports Scala 2.12, 2.13, and 3.x across all platforms, including Scala Native and Scala.js, as detailed in the cross-build version table in the README.

Question 4

How to set up sconfig with Scala Native?

Accepted Answer

Add the sconfig dependency with %%% in your build file and include a java.time library like sjavatime. Refer to the SCALA-NATIVE.md guide for specific version requirements and setup steps.

Question 5

What are the limitations of sconfig on Scala.js?

Accepted Answer

Scala.js only supports a subset of the API, so features like file system access or certain parsing options might be unavailable. Check the original documentation for gaps and test thoroughly in your project.

Question 6

Is sconfig production ready for Scala Native apps?

Accepted Answer

With CI testing, Scala Steward support, and releases on Maven Central, sconfig is stable. However, be cautious of the API subsets and extra dependencies, which might affect complex use cases on Scala Native.
