# QBJS toolchain image: compile QBJS BASIC to a deployable web app, and serve it.
# Unlike QB64PE (BASIC -> C++ -> native binary), QBJS transpiles BASIC -> JS, so
# this image needs only Node -- no C/C++ build toolchain.

# ---- Stage 1: fetch the QBJS runtime + compiler ----------------------------
FROM debian:12-slim AS fetch

RUN apt-get update && apt-get install -y --no-install-recommends \
      git ca-certificates \
    && rm -rf /var/lib/apt/lists/*

# QBJS has no release tag for 0.11.x (it ships from main); default to main but
# allow pinning any branch, tag, or commit SHA for reproducible builds.

RUN git clone --depth 1 --branch "${QBJS_REF}" "${QBJS_REPO}" /opt/qbjs \

# ---- Stage 2: runtime image -------------------------------------------------
FROM node:22-slim

# The hardened compiler must sit next to qb2js.js so its require('./qb2js.js')
# and qb-console.js's __dirname-based stdlib resolution both work.
