Npm scripts command not behaving like on shell

Question

I'm trying to concatenate an arbitrary number of Javascript files into one big one.

I have the following command declared in the scripts part of my package.json

"js:dev": "uglifyjs inz/js/**/*.js > 'ouz/haz/js/main.js'"

When I run npm run js:dev the file gets written, but always with empty content. If however I run the following directly on my shell (which is zsh) the expected contents get written into the file:

node_modules/uglifyjs/bin/uglifyjs inz/js/**/*.js > 'ouz/haz/js/main.js'

Why is this? I would expect both ways to behave the same. Is file globbing working differently in the context of npm run ?

Answer 1

I bet ** isn't supported there.

find inz/js -type f -name '*.js' -exec uglifyjs {} + >ouz/haz/js/main.js – 4ae1e1
