# hanzoai/nodejs — the ONE canonical Node base image for every Hanzo Node service.
#
# Node 24 (LTS "Krypton") + sqlite3 bundled two ways, BOTH proven at build time:
#   1. node:sqlite — the built-in DatabaseSync (stable since Node 22.5; present in
#      24). `require('node:sqlite')` works out of the box, zero dependencies.
#   2. native npm sqlite — better-sqlite3 / sqlite3 compile against the baked-in
#      toolchain (build-base + python3 + sqlite-dev) through node-gyp.
#
# One base, one way. Services do:  FROM ghcr.io/hanzoai/nodejs:v24.18.0
# Bump the pinned node:<ver>-alpine below to move the whole fleet's runtime;
# the git tag (vX.Y.Z) must match the Node version so consumers can reason about it.
FROM node:24.18.0-alpine

# Native addon build toolchain (node-gyp needs python3 + make + g++, all via
# build-base), the system sqlite CLI + headers, and the glibc shim so prebuilt
# (glibc) native addons load on musl. corepack ships pnpm/yarn shims.

# Build-time proof gate — the image FAILS TO BUILD if either sqlite path breaks.

#   (2) better-sqlite3 compiles from source against the toolchain and round-trips.
# The verify scratch dir is removed so it adds no weight to the published layer.
