I would like to publish a NPM package with a CLI utility in it. In the package.json, I have the following line:

"bin": "index.js"

When I install the package on Windows, a batch file is being generated under Roamingnpm, it’s called mypackage.cmd, and the final line goes:

"%dp0%node_modulesmypackageindex.js" %*

It’s not executing the script under Node.js, it’s executing the JavaScript file as is – not the desired result. On my dev box, for one, the default association for .js files is Visual Studio Code, not Node. Looking at other modules’ generated batch scripts, I see that the final line is different:

"%_prog%" "%dp0%node_modulesanotherpackagebinsomescript.js" %*

where _prog is initialized to the Node executable.

I want the bin script to execute explicitly under Node. What is missing in my package (presumably in package.json)?
