#
# indexer/Dockerfile — multi-stage image for the chain-follower indexer.
#
# Notes:
#   - better-sqlite3 has native components and needs python3 + make + g++ to
#     build during `pnpm install`. We install them in the builder stage only
#     and ship the prebuilt binding to the runtime image (no toolchain in
#     prod).
#   - We tried node:20-alpine first; better-sqlite3 11.x ships prebuilds for
#     musl on linux/x64 so it works without a fallback. If a future version
#     drops musl prebuilds, switch BUILDER_IMAGE to node:20-bookworm-slim and
#     replace `apk add` with `apt-get install -y python3 make g++`.
#   - Same tsx-based runtime as supplier (see supplier/Dockerfile for the
#     rationale: shared package exports .ts directly).
#
# Build:
#   docker build -f indexer/Dockerfile -t marketplace-indexer .
