#
# supplier/Dockerfile — multi-stage image for the supplier node.
#
# Strategy: install workspace deps in a builder stage, then ship the source
# tree + node_modules to a slim runtime stage that runs the entry point with
# tsx. We do NOT compile TypeScript ahead-of-time because @marketplace/shared
# exports .ts files via package.json#exports (`"./chain": "./src/chain/index.ts"`),
# which means a `tsc`-compiled `dist/index.js` cannot resolve those imports
# at runtime without an additional build step on the shared package. Running
# tsx is what apex-dashboard does and matches that working pattern.
#
# Build context MUST be the repo root so pnpm can resolve workspace deps:
#   docker build -f supplier/Dockerfile -t marketplace-supplier .
#
# Base image: node:20-alpine. Supplier has no native compile dependencies
# (@noble/ed25519, express, cbor-x are pure JS). Stay on alpine for size.
