IntelliJ Platform runs on JVM, yet Kotlin feels a lot like TypeScript. IntelliJ Platform SDK documentation is a good starting point.

Building and running the plugin

You'll need IntelliJ IDEA. The Community Edition is free and sufficient, you can also use Ultimate edition if you have one.

Clone the repository and run ./gradlew runIde (There are also intermediate tasks).

IntelliJ Ultimate will download in a bit, and you'll be prompted with license dialog - choose evaluation mode.

Ready to share .zip archive can be found in build/distributions after running ./gradlew buildPlugin.

Running tests

Tests can be run with ./gradlew test command or even better or by using run action in IntelliJ IDEA.

Writing Tests

Some tests in IntelliJ Platform are similar to Jest snapshots.

You need to create a .svelte file in scr/test/resources directory and add function composed of the word test and file name to appropriate class. When running test for the first time, file with expected results will be created, please commit it. When updating test, simply delete snapshot file and rerun test.
