In my experience, VS Code’s extension system really shines here. There are also boilerplate repos out there to get started.

Should be unnecessary (and might be outdated unless meticulously maintained) IF one chooses to just follow the VSC API docs' `yo code` approach. Which generates the project structure with a simple hello `extension.ts` IIRC.

They are meticulously maintained, and far more comprehensive than yo code.

For Jetbrains IDEs, I recommend using LivePlugin rather than building a full-blown plugin for every script: https://github.com/dkandalov/live-plugin

That's really awesome! As they support Groovy and Kotlin, they basically support most JVM languages too, so you can probably use this with Scala, Clojure etc.

I may give it a spin myself as I am pretty heavy user of IntelliJ.

By the way, I think Fleet, the new "Beta" editor by Jetbrains, is currently designing a custom plugin system to make it "nicer" to write plugins than for IntelliJ, but apparently it's not yet open for trials: https://www.jetbrains.com/help/fleet/managing-plugins.html
