How to pass babel options to @babel/register from command like require in node

Question

I have a script like "start": "node -r @babel/register ./src/start.js" and I want to pass in the rootMode option to @babel/register to have it find my config file. If I were requireing @babel/register in a file. I could do require('@babel/register')({rootMode: 'upward'}) . However I don't want to have an entrypoint script to each file like this.

Is there a way to pass options to babel register when requiring in command line node?

Answer 1

Just create register.js file like a

//register.js
require('@babel/register')({rootMode: 'upward'})

and then use script "start": "node -r ./register.js ./src/start.js"
