# shopdb-flask single-site container.
#
# One image, one site. Per ADR-004, each adopting facility runs its own
# stack with its own DB, secrets, and enabled-plugin list. This image
# bundles all 13 catalog plugins (computers, employees, geenforce,
# knowledgebase, machines, measuringtools, network, notifications,
# printedparts, printers, slides, usb, warranty); a site installs + enables
# the ones it wants with `flask plugin install <name>` (or, declaratively,
# `flask plugin apply-profile <profile.json>`). Per ADR-013 a future lean
# build stages only the chosen plugin directories into this image.
#
# The frontend is built in a first stage and its dist output is copied into
# the final image so Flask can serve the SPA (register_frontend_routes in
# shopdb/__init__.py resolves <repo>/frontend/dist).
#
# Build:
#   docker build -t shopdb-flask .
# Run (with .env):
#   docker run --env-file .env -p 5001:5001 shopdb-flask

COPY frontend/package*.json ./frontend/
RUN cd frontend && npm ci

# The frontend keeps its repo-relative layout here, because npm prebuild runs
# `node ../scripts/stage-frontend.mjs`, which stages each plugin's frontend/ into
# the Vite tree and codegens routes.gen.js. That script resolves its repo root as
# its own directory's parent, so it needs scripts/ and plugins/ as SIBLINGS of
# frontend/. Building with frontend/ flattened to the stage root made `../scripts`
# resolve to /scripts and the build failed on a missing module.

# Output lands in /build/frontend/dist (Vite default), copied into the final
