subprogram

Utility to turn individual ES modules into programs that can be run.

$3

You can turn ES module into runnable node program. This is an ES alternative to if (require.main === module) { ... } pattern.

``js
import { script } from "subprogram"

export const main () => {
console.log("Hello world")
}

script({ ...import.meta, main })
`

When above program is run as node script.js it will run a main` function of the module, if module is imported no action will take place.
