# Balinyaar web client — build context is `client/` (see the root docker-compose.yml).
#
# NEXT_PUBLIC_* values are inlined into the browser bundle by `next build`, so the API URL and site origin
# are BUILD-time inputs, not runtime env vars — setting them in compose would do nothing. They come from the
# committed .env.production, which `next build` reads because it runs with NODE_ENV=production; change a value
# there and rebuild the image.

# package-lock.json is generated on Windows, where npm filters out the wasm32-only optional packages and so
# never records their transitive deps (@emnapi/core, @emnapi/runtime). On Linux npm does want them, and a
# bare `npm ci` dies on the lockfile-sync check. --omit=optional is NOT the fix: Turbopack's @parcel/watcher
# resolves its native binary through optionalDependencies, so omitting them breaks `next build` outright.
#
# So: complete the lock here, on the platform that can actually see those packages, then install from it.
# --package-lock-only reuses every version already pinned in the committed lock and only ADDS the missing
# Linux-side entries, so this stays effectively reproducible rather than a free-for-all `npm install`.
# Drop the first command once the committed lock is generated on Linux (see DEPLOY.md).
