How to set default runtime options for node?

Question

I am using arrow functions in my code, thus I need to be using --harmony_arrow_functions option when running the code, e.g.

node --harmony_arrow_functions ./my-script.js

How do I make --harmony_arrow_functions a default option for every time I use node?

Answer 1

Either add a wrapper script in your PATH that sets the command line options.

Or you could define a start script in your package.json.

{
    "scripts": {
        "start": "node --harmony_arrow_functions my-script.js"
    }
}

And run npm start to run your script.
