# Multi-stage build for the CurrenciCombo portal (Vite + React).
#
# Context MUST be the repo root so the vite build can see src/, public/,
# index.html, etc.:
#
#   docker build -t currencicombo/portal:local .
#
# VITE_ORCHESTRATOR_URL is baked at build time (Vite inlines env vars
# prefixed with VITE_). In a sandbox compose, set it to whatever URL
# the browser uses to reach the orchestrator — typically
# http://localhost:8080 if the orchestrator's port is published on the
# host. When unset, the portal runs in its built-in demo-fallback mode
# (see src/services/orchestrator.ts).

# vite 7 ships @rolldown/binding-* as platform-matched optional deps,
# so we MUST include optional deps (skipping them breaks `vite build`
# with "Cannot find native binding"). `fsevents` is also optional but
# darwin-only; on linux npm 10 trips EBADPLATFORM on the lockfile
# entry even though the runtime would never load it. `--force` downgrades
# that EBADPLATFORM to a warning while still installing the rolldown
# binding for the current platform.
