# Multi-stage build for the helix-engage sidecar.
|
|
#
|
|
# Why multi-stage instead of "build on host, COPY dist + node_modules"?
|
|
# The host (developer Mac, CI runner) is rarely the same architecture
|
|
# as the target (linux/amd64 EC2 / VPS). Copying a host-built
|
|
# node_modules brings darwin-arm64 native bindings (sharp, livekit,
|
|
# fsevents, etc.) into the runtime image, which crash on first import.
|
|
# This Dockerfile rebuilds inside the target-platform container so
|
|
# native bindings are downloaded/compiled for the right arch.
|
|
#
|
|
# The build stage runs `npm ci` + `nest build`, then `npm prune` to
|
|
# strip dev deps. The runtime stage carries forward only `dist/`,
|
|
# the pruned `node_modules/`, and `package.json`.
