# =========================================
# 阶段 1: 准备 Node 环境
# =========================================
FROM node:22-bookworm-slim AS node_base

# =========================================
# 阶段 2: 构建最终镜像 (基于 Manim)
# =========================================
FROM manimcommunity/manim:stable
USER root

# 1. 复制 Node.js (从 node_base 偷过来)
COPY --from=node_base /usr/local/bin /usr/local/bin
COPY --from=node_base /usr/local/lib/node_modules /usr/local/lib/node_modules

# 2. 【关键】安装 Redis 和中文字体，并刷新字体缓存
# 使用阿里云源加速
RUN sed -i 's/deb.debian.org/mirrors.aliyun.com/g' /etc/apt/sources.list.d/debian.sources && \
    apt-get update && \
    apt-get install -y redis-server fontconfig \
    fonts-noto-cjk fonts-noto-cjk-extra \
    fonts-wqy-zenhei fonts-wqy-microhei fonts-lxgw-wenkai \
    ffmpeg curl ca-certificates && \
    fc-cache -f -v

# 2.1 安装 Python 运行时与静态检查依赖
#     显式声明 matplotlib，避免依赖基础镜像的隐式预装状态。
RUN python -m pip install --no-cache-dir \
    matplotlib \
    mypy==1.19.1

WORKDIR /app

# 3. 复制 package.json
COPY package.json package-lock.json* ./
COPY frontend/package.json frontend/package-lock.json* ./frontend/

# 4. 设置 npm 淘宝源
RUN npm config set registry https://registry.npmmirror.com

# 5. 安装依赖
RUN npm install && npm --prefix frontend install

# 6. 复制源码并构建 React
COPY . .

# 7. 下载 BGM 音频文件（HF Space 同步时可能排除二进制文件）
#    之前写法使用了 `... && ... && ... || true`，会把前面下载失败静默吞掉。
