# api service
# I typically start with a clean base image that doesn't have any 
# transient dependencies, but in your case you'd still want pnpm etc 
# but i don't want any unecessary node_modules or build artifacts 
# that aren't helpful at runtime so a clean filesystem is helpful.
FROM node:18-alpine as api

WORKDIR /app

# Then I only want runtime files for the specific target.
# If a monorepo I may need to copy other resources, and maybe 
# a root node_modules or something.
