Answer 1

I have created the following, and it's working on my system. Please try this:

package.json:

{
  "name": "test app",
  "version": "1.0.0",
  "scripts": {
    "start": "node script1.js"   
  }
}

script1.js:

console.log('testing')

From your command line run the following command:

npm start

Additional use case

My package.json file has generally the following scripts, which enable me to watch my files for typescript, sass compilations and running a server as well.

 "scripts": {
    "start": "concurrently \"sass --watch ./style/sass:./style/css\" \"npm run tsc:w\" \"npm run lite\" ",    
    "tsc": "tsc",
    "tsc:w": "tsc -w", 
    "lite": "lite-server",
    "typings": "typings",
    "postinstall": "typings install" 
  }
