# ============================================================
# Stage 1: 构建前端 (Node 22)
#   产出 web/dist（Vite 默认配置：root=构建目录, outDir=dist）
# ============================================================
FROM node:22-slim AS frontend
WORKDIR /build
# 先装依赖以利用 Docker 层缓存
COPY web/package.json web/package-lock.json ./
RUN npm ci
# 再拷源码并构建（产物输出到 /build/dist）
COPY web/ ./
# 共享设计系统 input.css 由 app/ 提供，本地以 ../../app/static/src/input.css 引用；
# 构建阶段仅拷贝了 web/，须同步该目录到相对路径对应的 /app/static/src/ 下，否则 vite 解析失败。
COPY app/static/src/ /app/static/src/
RUN npm run build

# ============================================================
# Stage 2: 运行环境 (Python 3.13)
# ============================================================
