构建脚本

1. 主构建脚本 (npm run build)

主构建命令负责整个构建流程:

{
  "scripts": {
  "build": "npm run generate-analysis && hugo --environment production --minify && npm run compress-json"
  }
}

构建阶段:

  1. 内容分析生成 (npm run generate-analysis)
  2. Hugo 静态网站生成 (hugo --environment production --minify)
  3. 搜索索引压缩 (npm run compress-json)

2. 内容分析脚本

文件: scripts/generate-analysis-data.js

用途: 生成网站内容的综合分析数据

// 主要功能
const contentAnalysis = {
  // 扫描所有内容文件
  scanContent: async () => {
  const contentFiles = await glob('content/**/*.md');
  return contentFiles.map(file => analyzeFile(file));
  },

  // 生成统计数据
  generateStats: (pages) => ({
  totalPages: pages.length,
  pagesByType: groupByType(pages),
  pagesByCategory: groupByCategory(pages),
  readingTimeStats: calculateReadingTimes(pages),
  contentGrowth: analyzeGrowthTrends(pages),
  popularTags: getPopularTags(pages)
  }),

  // 导出数据
  exportData: (data) => {
  fs.writeFileSync('data/content_analysis.json', JSON.stringify(data, null, 2));
  console.log(`已生成 ${data.totalPages} 页的分析数据`);
  }
};

输出: 生成 data/content_analysis.json,包含网站分析数据

3. 搜索索引压缩

文件: scripts/build.js

用途: 压缩搜索索引文件,加快加载速度

const compressSearchIndex = async () => {
  // 读取 Hugo 配置
  const config = toml.parse(fs.readFileSync('config/_default/config.toml', 'utf8'));
  const languages = Object.keys(config.languages || { zh: {}, en: {} });

  // 处理每种语言
  for (const lang of languages) {
  const indexPath = `public/${lang}/index.json`;
  const outputPath = `public/search-index/${lang}/index.json.gz`;

  if (fs.existsSync(indexPath)) {
    // 使用 gzip 压缩
    const data = fs.readFileSync(indexPath);
    const compressed = pako.gzip(data);

    // 确保输出目录存在
    fs.mkdirSync(path.dirname(outputPath), { recursive: true });
    fs.writeFileSync(outputPath, compressed);

    console.log(`已压缩 ${lang} 搜索索引:${data.length}${compressed.length} 字节`);
  }
  }
};

4. Mermaid 图表处理

文件: scripts/transform-mermaid.js

用途: 将 Mermaid 图表转换为 SVG,提高性能

const transformMermaid = async () => {
  // 查找所有包含 Mermaid 图表的 Markdown 文件
  const files = await glob('content/**/*.md');

  for (const file of files) {
  const content = fs.readFileSync(file, 'utf8');
  const mermaidBlocks = extractMermaidBlocks(content);

  if (mermaidBlocks.length > 0) {
    let updatedContent = content;

    for (const block of mermaidBlocks) {
    // 使用 Mermaid CLI 生成 SVG
    const svgPath = await generateSVG(block.code, file);

    // 用图片引用替换 Mermaid 块
    const imageTag = `![${block.title || 'Diagram'}](diagram.svg)`;
    updatedContent = updatedContent.replace(block.original, imageTag);
    }

    // 写入更新后的内容
    fs.writeFileSync(file, updatedContent);
    console.log(`已处理 ${file} 中的 ${mermaidBlocks.length} 个图表`);
  }
  }
};

const generateSVG = async (mermaidCode, sourceFile) => {
  const outputPath = sourceFile.replace('.md', '-diagram.svg');

  // 使用 Mermaid CLI 生成 SVG
  await execAsync(`mmdc -i temp-diagram.mmd -o ${outputPath} -c mermaid-config.json`);

  return outputPath;
};

5. 图片处理脚本

图片尺寸添加

文件: scripts/add-image-dimensions.js

用途: 自动为图片添加宽高属性

const addImageDimensions = async () => {
  const files = await glob('content/**/*.md');

  for (const file of files) {
  const content = fs.readFileSync(file, 'utf8');
  const images = extractImages(content);
  let updatedContent = content;

  for (const image of images) {
    if (!image.hasDimensions) {
    try {
      const dimensions = await getImageDimensions(image.src);
      const updatedImage = `${image.original}\n{width=${dimensions.width} height=${dimensions.height}}`;
      updatedContent = updatedContent.replace(image.original, updatedImage);
    } catch (error) {
      console.warn(`无法获取 ${image.src} 的尺寸:${error.message}`);
    }
    }
  }

  if (updatedContent !== content) {
    fs.writeFileSync(file, updatedContent);
    console.log(`已更新 ${file} 中的图片尺寸`);
  }
  }
};

const getImageDimensions = async (imagePath) => {
  if (imagePath.startsWith('http')) {
  // 远程图片
  const response = await fetch(imagePath);
  const buffer = await response.arrayBuffer();
  return sizeOf(Buffer.from(buffer));
  } else {
  // 本地图片
  const fullPath = path.join('static', imagePath);
  return sizeOf(fullPath);
  }
};

图片上传与优化

文件: scripts/upload-images.js

用途: 优化图片并上传到 CDN

const optimizeAndUpload = async () => {
  // 查找最近修改的图片
  const images = await findRecentImages();

  for (const image of images) {
  // 优化图片
  const optimized = await optimizeImage(image);

  // 上传到 Cloudflare R2
  await uploadToR2(optimized);

  // 更新内容中的图片引用
  await updateImageReferences(image.path, optimized.cdnUrl);
  }
};

const optimizeImage = async (imagePath) => {
  const image = sharp(imagePath);
  const metadata = await image.metadata();

  // 生成多种格式和尺寸
  const formats = ['webp', 'avif', 'jpeg'];
  const sizes = [400, 800, 1200, 1600];

  const optimized = [];

  for (const format of formats) {
  for (const size of sizes) {
    if (size <= metadata.width) {
    const output = await image
      .resize(size)
      .toFormat(format, { quality: 85 })
      .toBuffer();

    optimized.push({
      format,
      size,
      buffer: output,
      filename: `${path.basename(imagePath, path.extname(imagePath))}-${size}w.${format}`
    });
    }
  }
  }

  return optimized;
};

Hugo 构建配置

1. 环境配置

开发环境配置:

# config/development/config.toml
baseURL = "http://localhost:1313"
buildDrafts = true
buildFuture = true
buildExpired = true

[params]
enable_comment = false
google_analytics_id = ""

生产环境配置:

# config/production/config.toml
baseURL = "https://jimmysong.io"

    keepWhitespace = false
  [minify.tdewolff.css]
    keepCSS2 = true
  [minify.tdewolff.js]
    keepVarNames = false

2. 资源管道配置

PostCSS 配置 (postcss.config.js):

module.exports = {
  plugins: [
  require('autoprefixer'),
  ...(process.env.HUGO_ENVIRONMENT === 'production' ? [
    require('@fullhuman/postcss-purgecss')({
    content: [
      './layouts/**/*.html',
      './content/**/*.md',
      './assets/js/*.js'
    ],
    defaultExtractor: content => content.match(/[\w-/:]+(?<!:)/g) || [],
    safelist: [
      // 保留动态类名
      /^hljs/,
      /^mermaid/,
      /^markmap/,
      /^toast/,
      /^giscus/
    ]
    })
  ] : [])
  ]
};

Hugo Pipes 配置:

<!-- layouts/partials/head.html -->
{{ $options := (dict "targetPath" "css/style.css" "outputStyle" "compressed") }}
{{ $style := resources.Get "scss/style.scss" | toCSS $options | postCSS | minify | fingerprint }}
<link rel="stylesheet" href="{{ $style.RelPermalink }}" integrity="{{ $style.Data.Integrity }}">

{{ $js := resources.Get "js/main.js" | js.Build (dict "minify" true) | fingerprint }}
<script src="{{ $js.RelPermalink }}" integrity="{{ $js.Data.Integrity }}" defer></script>

  projectName: jimmysong-io
  directory: public
  gitHubToken: ${{ secrets.GITHUB_TOKEN }}

性能优化

1. 构建性能

并行处理:

# 利用多核 CPU
export HUGO_NUMWORKERTHREADS=8
hugo --gc --minify --cleanDestinationDir

增量构建:

# 开发环境:快速增量构建
hugo server --gc

# 生产环境:全量清理构建
hugo --gc --minify --cleanDestinationDir

缓存策略:

# Hugo 资源缓存
export HUGO_CACHEDIR=./cache
hugo --gc --minify

2. 资源优化

CSS 优化:

// 关键 CSS 提取
@import 'critical';  // 首屏样式

// 非关键 CSS 异步加载
@import 'non-critical';

JavaScript 优化:

// 代码分割
const loadModule = async (moduleName) => {
  const module = await import(`./modules/${moduleName}.js`);
  return module.default;
};

// 懒加载
const observer = new IntersectionObserver((entries) => {
  entries.forEach(entry => {
  if (entry.isIntersecting) {
    loadModule('interactive-component');
  }
  });
});

图片优化流程:

// 多格式图片生成
const generateResponsiveImages = async (imagePath) => {
  const formats = ['avif', 'webp', 'jpeg'];
  const sizes = [400, 800, 1200, 1600];

  const variants = [];

  for (const format of formats) {
  for (const size of sizes) {
    const variant = await sharp(imagePath)
    .resize(size)
    .toFormat(format, { quality: 85 })
    .toBuffer();

    variants.push({ format, size, buffer: variant });
  }
  }

  return variants;
};

监控与分析

1. 构建监控

构建性能采集:

// 构建性能跟踪
const buildMetrics = {
  startTime: Date.now(),
  stages: {},

  startStage: (name) => {
  buildMetrics.stages[name] = { start: Date.now() };
  },

  endStage: (name) => {
  const stage = buildMetrics.stages[name];
  stage.end = Date.now();
  stage.duration = stage.end - stage.start;
  console.log(`${name}: ${stage.duration}ms`);
  },

  finish: () => {
  const totalTime = Date.now() - buildMetrics.startTime;
  console.log(`总构建时间:${totalTime}ms`);

  // 发送指标到监控服务
  sendMetrics(buildMetrics);
  }
};

2. 内容分析

内容性能跟踪:

// 内容分析指标
const analyzeContent = (pages) => {
  return {
  totalPages: pages.length,
  averageWordCount: pages.reduce((sum, p) => sum + p.wordCount, 0) / pages.length,
  contentByType: groupBy(pages, 'type'),
  contentByCategory: groupBy(pages, 'category'),
  readingTimeDistribution: calculateReadingTimeDistribution(pages),
  contentFreshness: analyzeContentFreshness(pages)
  };
};

故障排查

常见构建问题

1. Hugo 构建失败

问题: Hugo 构建时模板报错

诊断:

# 使用详细输出运行 Hugo
hugo --verbose --debug

# 检查模板语法

解决方案:

  • 检查 layouts 目录下模板语法
  • 校验 front matter 结构
  • 确认所有必需的 partials 存在

2. 资源处理失败

问题: CSS/JS 处理失败

诊断:

# 检查 PostCSS 配置
npx postcss --version

# 测试 SCSS 编译
hugo server --verbose

解决方案:

  • 检查 PostCSS 插件是否安装
  • 检查 SCSS 语法
  • 确认资源路径正确

3. 内存问题

问题: 构建时内存不足

解决方案:

# 增加 Node.js 内存限制
export NODE_OPTIONS="--max-old-space-size=4096"

hugo --gc --cleanDestinationDir

4. 构建速度慢

问题: 构建耗时过长

优化建议:

# 启用并行处理
export HUGO_NUMWORKERTHREADS=8

# 开发环境使用增量构建
hugo server --gc

# 构建性能分析
hugo --templateMetrics --templateMetricsHints

调试模式

开启详细调试:

# Hugo 调试模式
HUGO_DEBUG=true hugo server --debug --verbose

# Node.js 调试模式
