# Script for downloading some WebUI's NPM deps without using `npm install`.
# Unfortunately `npm install` downloads a lot of unnecessary dependencies in
# many cases. This is especially true for cases like 'mocha'and 'chai', which
# even though come already bundled, NPM still downloads about ~8MB of
# unnecessary dependencies.
#
# To address the problem above and avoid blowing up the size of the generated
# node_modules.tar.gz file, this script directly downloads just the necessary
# packages, since NPM does not provide such functionality built-in, see
# https://github.com/npm/npm/issues/340.
