Is it possible to get what package.json script has been called in NodeJS code?

Is it possible to get what package.json script has been called in NodeJS code?

My package.json file contains a script that builds the application:

{
    "name": "notes-app",
    "version": "0.0.1",
    "license": "MIT",
    "scripts": {
        "ng": "ng",
        "start": "ng serve",
        "build": "ng build && node server.js"
    },
    etc, etc...

Can I then write in my server.js file an if statement like:

if (script === 'build') {
  // Do something
}

Is there a way of knowing what script was called when starting the app. I would start this using the command npm run build. Also I'm using windows if that would make any difference.
