# https://dev.to/xcanchal/automatic-versioning-in-a-lerna-monorepo-using-github-actions-4hij
# Problems:
#   I tried to use github registry to publish public packages,
#   but packages in github require auth to install even if package is public.
#
#   Npm token will not be configured without registry-url set in actions/setup-node
#   To configure authToken for npm both registry-url and secret is needed.
#   When publishing public package, publishConfig.access need to be configured on each package
#
#   Lerna need fetch-depth: 0 (full fetch) on checkout to be able generate full changelog
