I had a similar question awhile back and didn't get a response so resorted to posting the zip file from NetSuite to be opened on an external Node.js endpoint where I used adm-zip. However since then I remember I believe it was @alien4u who posted a link to a site that would allow you to get any npm module in a state for use in NetSuite. @alien4u assuming my memory's correct could something like adm-zip or another npm zip module be easily brought into NetSuite.
