# Multi-stage Dockerfile for ActaLog
# Builds both frontend and backend in a single optimized image

# ============================================================================
# Stage 1: Build Frontend (Vue.js)
# ============================================================================
FROM node:24-alpine@sha256:a0b9bf06e4e6193cf7a0f58816cc935ff8c2a908f81e6f1a95432d679c54fbfd AS frontend-builder

# Copy package files
COPY web/package.json web/package-lock.json ./

# Pin npm to the version that generated package-lock.json. The node:24-alpine
# base image's bundled npm floats across rebuilds; a newer npm reshapes the
# rolldown wasm-fallback @emnapi optional deps and breaks `npm ci`. Keep this in
# lockstep with the "packageManager" field in web/package.json.
RUN npm i -g npm@11.16.0

# Install dependencies (including dev dependencies needed for build)
