#
# Setup
#
# Use FROM node:lts-alpine for minimum file size
# Use FROM node:lts-slim for maximum compatibility

#
# To print commands and debug building dockerfile use:
#
# RUN pwd && ls -a
#
# To see full docker logs run the following command:
#
# docker build . --progress=plain

# Don't generate the client on dependency install, as we'll do it later
