Dockerfile.vote.template

# ============================================================
# THVote Vote App Dockerfile 模板
#
# 构建时由 CI workflow 内联生成（使用 heredoc）
# 多阶段构建：从源代码构建
#
# 使用方式（在 workflow 中）：
#   docker build -t $TAG --build-arg BACKEND_URL=http://backend:8000 -f - . << 'EOF'
#   $(cat Dockerfile.vote.template)
#   EOF
# ============================================================

# ---- Build Stage ----
FROM node:20-alpine AS build

# 安装 pnpm
RUN corepack enable && corepack prepare pnpm@10.33.0 --activate

WORKDIR /app

# 设置 pnpm store
ENV PNPM_HOME=/pnpm
ENV PATH=$PNPM_HOME:$PATH

# 复制源代码
COPY . .

# 安装依赖
RUN pnpm install --frozen-lockfile

# 设置 GraphQL schema 获取地址（构建时通过 --build-arg 传入）
ARG BACKEND_URL=http://localhost:8000

# 预下载 schema（如果本地存在则跳过）
# codegen 在 CI 中由 workflow 执行，此处仅保留占位
# RUN echo "GraphQL schema 从 ${BACKEND_URL} 获取"

# 构建应用
RUN pnpm --filter @touhou-vote/vote run build -- --mode test

# ---- Production Stage ----
FROM nginx:alpine

# 监听 8082（与 test 环境配置一致）
RUN echo 'server { \
    listen 8082; \
    location / { \
        root /usr/share/nginx/html; \
