@mumblebaj why my install script does npm install --only=prod
to remove the dev dependencies

[mumblebaj]

@sdetweil :thumbs_up:

@richard238 there are dependencies

things needed to RUN

and dev dependencies,

things needed to DEVELOP for existing or new function

things like syntax checkers, format checkers, test cases, … 99% of users don’t need that stuff on their disc

in the package.json are two lists of dependencies
“devDependencies”: {
“dependencies”: {

unless u specify only runtime (production) , you get both …

[Richard238]

I’ll reboot, because, why not…
