# PRUNE TO GET DEPENDENCIES [pruner]
# ===================================

# Use turbo to prune package dependencies
FROM base AS pruner

# work in /app folder
WORKDIR /app

# install turbo global
RUN npm install turbo@^2.0.11 -g

# copy everything into pruner
COPY . .

# prune using turbo for only faims3 and it's dependencies. This produces an
# /app/out folder which has /full (all needed deps) or /json (package*.json
# only)
RUN turbo prune ${PACKAGE_NAME} --docker


# INSTALL PACKAGES [builder]
# ============================

# add lockfiles dependencies
FROM base AS builder

WORKDIR /app

# Install dependencies
COPY .gitignore .gitignore
COPY --from=pruner /app/out/json/ .

# install turbo global
RUN npm install turbo@^2.0.11 -g
RUN npm install


# Build the project 
COPY --from=pruner /app/out/full/ .
COPY --from=pruner /app/out/json/ json

# build packages using turbo
RUN turbo run build --filter=${PACKAGE_NAME}

# Package all necessary files to run app into pruner out
COPY bundle.sh .
RUN sh bundle.sh json . out && cp -R json/* /app/out/

# PRODUCTION RUNNER [runner]
# ==========================

FROM alpine AS runner

# Don't run production as root
RUN addgroup --system --gid 1001 nodejs
RUN adduser --system --uid 1001 faims
