import.meta.url undefined

[LangLangBart]

to reproduce

• create a folder and install @digitak/esrun
• add type:module to your package.json

{
	"type": "module",
	"dependencies": {
		"@digitak/esrun": "^3.2.24",
	}
}

• create a test.ts file with one line console.log(import.meta.url)
• run the file with esrun, notice the output is undefined

node_modules/.bin/esrun test.ts
# undefined

expected result

• install esbuild and run the test.ts with esbuild
• the output is correct

node_modules/.bin/esbuild test.ts --bundle --format=esm --platform=node --outfile=build.js --loader:.ts=ts
node build.js
# file:///Users/paria/Developer/esrun_test/build.js

workaround

• one can use __dirname and __filename
  • eslint-plugin-unicorn recommends not to use it

additional notes

• node v20.0.0
• @digitak/esrun ^3.2.24 (3.2.25 is not available via npm)
• esbuild ^0.17.18
• If I use the VSCode debugger with these settings in my launch.json the output is also correct. It uses esbuild-register, can esrun also be used for this task, then I would need one dependency less in my setup?
