node.js - How to access flag passed to npm script -

-

in package json created seed script uses mocha initialize environment , run bunch of database calls:

"seed": "./node_modules/.bin/mocha seed/seed-bootstrap.js seed/seed.js"

i want able pass flag specifies seed number determine how many of each object created run

npm run script --seednum=10

and have 10 of each object created.

i can't figure out how access value of seednum inside script. thought in process.argv not. process.argv seems contain contents of mocha.opts file.

like so:

npm run seed -- --seednum=4

as per

https://docs.npmjs.com/cli/run-script

apparently first -- used npm delimiter arguments intended npm , arguments thereafter intended script.
