Answer 1

Suppose I have this line of scripts in my "package.json"

"scripts": {
    "test": "echo \"Error: no test specified\" && exit 1",
    "export_advertisements": "node export.js advertisements",
    "export_homedata": "node export.js homedata",
    "export_customdata": "node export.js customdata",

Now to run the script "export_advertisements", I will simply go to the terminal and type

npm run export_advertisements

You are most welcome
