# Copy JUST the package files first.
# This allows Docker to NOT re-fetch all NPM packages if neither of these two files
# have changed, and instead use the cached layer containing all those dependent packages.
# Greatly speeds up repeated docker build calls on the same machine (like CI/CD boxes) 
# by leveraging the docker image cache

# DTUI and Usaspending-website have preinstall scripts that run npx npm-force-resolutions
# the command will fail unless specifically pointing to npm-force-resolution@0.0.3
# With the current dependencies we need --legacy-peer-deps in both npm install and ci
# The npm ci will fail without npm install --package-lock-only due to dependency differences
