You can work around this by putting a why-is-node-running.d.ts file within your project, in a place where your tsconfig.json will instruct that it be compiled, and fill it with these contents:

interface WithConsoleErrorStyleMethod {
	error: Console['error']
}

declare module 'why-is-node-running' {
	export default function log(logger?: WithConsoleErrorStyleMethod): void
}

Then import whyIsNodeRunning from 'why-is-node-running' and do whyIsNodeRunning() to trigger the dumping using console.error -- or pass your own object with a 'error' property that behaves like console.error does, if you want to do something cuter.
