# --- Stage 1: build the Vue frontend ---------------------------------------
FROM node:24-alpine AS frontend

WORKDIR /web

# Dependencies in their own layer, cached unless the manifests change. npm ci
# resolves this stage's (musl) platform binaries for rollup/esbuild. The cache
# mount keeps the npm download cache warm across builds, so a lockfile bump
# only re-fetches what actually changed.
COPY web/package.json web/package-lock.json ./
RUN --mount=type=cache,target=/root/.npm npm ci

COPY web/ ./
RUN npm run build          # vue-tsc type-check, then `vite build` -> /web/dist

# --- Stage 2: PHP + Apache runtime, on Alpine -------------------------------
FROM alpine:3.24

# apk's php83 packages are prebuilt (no compiling PHP from source, unlike the
# official Debian php:8.3-apache image), and split finely enough to pull in
# only what this app actually uses. php83-apache2 is Alpine's mod_php SAPI
# module -- the same role as php:8.3-apache's --with-apxs2 build. This alone
# takes the final image from ~735MB to ~90MB.
RUN apk add --no-cache \

    # script (copied in below) and bin/migrate.php's shebang both expect one.
    && ln -s /usr/bin/php83 /usr/local/bin/php

# --- Composer ----------------------------------------------------------------
# Borrowed from the official composer image rather than apk's own `composer`
# package, which drags in an entire second PHP interpreter (php85) as a
# dependency just to run the phar -- multi-stage COPY takes only the binary.
COPY --from=composer:2 /usr/bin/composer /usr/bin/composer

# --- Apache: document root -> public/, allow .htaccess rewrites -------------
COPY docker/apache.conf /etc/apache2/conf.d/zz-app.conf

# --- Entrypoint: migrate, then hand off to Apache ---------------------------
# Copied early, alongside the other rarely-changing setup above -- after
# COPY . . (below) every later layer re-runs on nearly every build, so this
# would otherwise redo work for a file that essentially never changes.
COPY --chmod=0755 docker/entrypoint.sh /usr/local/bin/entrypoint.sh

WORKDIR /var/www/html

# --- PHP dependencies (own layer, cached unless composer.* changes) --------
# The cache mount keeps Composer's package cache warm across builds, so a
# composer.lock bump only re-fetches the packages that changed.
