I've forked this project. My fork can be found here.

I've tried to limit myself to upgrading the Scala 3 version to the LTS version, and upgrading the core dependencies to their latest versions supporting Scala 3. In terms of source code changes, this has been completely trivial.

However, when I stand everything up and run sbt smoke, the test fails due to a websocket connection timing out, and several of the expected messages not being received.

Doing the same with the original code passes using the same JVM on the same host.

Looking at the evolving dependencies, my biggest concern is the changes to the http4s JDK client used for websocket support. It appears to have undergone significant revision from M6 to M7, revolving around new cats-effect capabilities. However, neither reverting to M6 (the last version in which simple returns a Resource) and M3 (the version used in the original code) solves the problem. Nevertheless, the finicky-looking nature of the websocket client with respect to state and lifecycles continues to make me nervous.

Any suggestions would be greatly appreciated.

Iron v2.0.0 supports Scala.js. AFAIK it was the only reason Symbol has two implementation (JVM/JS).

It can now be merged into the "shared" code.

Requires Scala 3 support in the Neutron library.
