# Address Elements lives on our CDN in S3. Each version has its own folder and its file names are
# always the same. Here is an example:
#   https://cdn.lob.com/lob/address-elements/X.X.X/address-elements.min.js
# However in our repo, version numbers are appended to each minified build. This script removes
# any mentions of a version number. It also creates the merged files used which include our
# minified code with project dependencies (jQuery, Algolia)

# Get package version
PACKAGE_VERSION=$(cat package.json \
  | grep version \
  | head -1 \
  | awk -F: '{ print $2 }' \
  | sed 's/[",]//g')
