Static Site Generator Technical Specification

Task: A.4.2 — Build static site generator from Vite configuration Track: A — Presentation & Publishing Platform Status: Active Version: 1.0.0

1. Executive Summary​

This specification defines the production build pipeline for the BIO-QMS Documentation Viewer, transforming a Vite+React development environment into an optimized static site suitable for CDN deployment. The generator processes 133 documents (99 markdown + 28 JSX dashboards + 6 configuration files) with a strict 5MB total size budget, pre-rendering content, optimizing assets, and implementing aggressive code splitting strategies.

2. Vite Configuration for Production​

2.1 Base Configuration (vite.config.js)​

The current configuration provides static asset copying; production enhancements add optimization, chunking, and minification:

// vite.config.js (PRODUCTION CONFIGURATION)
import { defineConfig } from "vite";
import react from "@vitejs/plugin-react";
import tailwindcss from "@tailwindcss/vite";
import { viteStaticCopy } from "vite-plugin-static-copy";
import { visualizer } from "rollup-plugin-visualizer";
import compression from "vite-plugin-compression";

export default defineConfig(({ mode }) => ({
  plugins: [
    tailwindcss(),
    react({
      // Babel optimizations for production
      babel: {
        plugins: mode === "production" ? [
          ["transform-react-remove-prop-types", { removeImport: true }],
          ["@babel/plugin-transform-react-constant-elements"],
        ] : [],
      },
    }),

    // Copy markdown and static assets to dist/
    viteStaticCopy({
      targets: [
        { src: "docs/**/*.md", dest: "docs" },
        { src: "research/**/*.md", dest: "research" },
        { src: "internal/**/*.md", dest: "internal" },
        { src: "public/publish.json", dest: "." },
        { src: "public/coditect-logo.png", dest: "." },
      ],
    }),

    // Gzip + Brotli compression for CDN
    compression({ algorithm: "gzip", ext: ".gz" }),
    compression({ algorithm: "brotliCompress", ext: ".br" }),

    // Bundle analysis (development only)
    mode === "development" && visualizer({
      filename: "dist/stats.html",
      open: false,
      gzipSize: true,
      brotliSize: true,
    }),
  ].filter(Boolean),

  // Production build options
  build: {
    outDir: "dist",
    assetsDir: "assets",
    sourcemap: mode === "development",
    minify: "terser", // More aggressive than esbuild

    terserOptions: {
      compress: {
        drop_console: true, // Remove console.* in production
        drop_debugger: true,
        pure_funcs: ["console.log", "console.info"],
      },
    },

    // Code splitting configuration
    rollupOptions: {
      output: {
        manualChunks: {
          // Vendor chunk: React + React-DOM
          vendor: ["react", "react-dom"],

          // Markdown processing libraries
          markdown: [
            "unified",
            "remark-parse",
            "remark-gfm",
            "remark-math",
            "remark-frontmatter",
            "remark-rehype",
            "rehype-raw",
            "rehype-highlight",
            "rehype-katex",
            "rehype-slug",
            "rehype-autolink-headings",
            "rehype-stringify",
          ],

          // Search engine
          search: ["minisearch", "gray-matter"],

          // Math + syntax highlighting
          katex: ["katex"],
          highlight: ["highlight.js"],

          // Diagram rendering
          mermaid: ["mermaid"],

          // Icons
          icons: ["lucide-react"],
        },

        // Dashboard lazy-load chunks (automatic, named by route)
        chunkFileNames: (chunkInfo) => {
          if (chunkInfo.name.startsWith("dashboards-")) {
            return `assets/dashboard-${chunkInfo.name.replace("dashboards-", "")}-[hash].js`;
          }
          return "assets/[name]-[hash].js";
        },

        // Asset naming with cache-busting hashes
        assetFileNames: (assetInfo) => {
          const ext = assetInfo.name.split(".").pop();
          if (/png|jpe?g|svg|gif|webp|avif/i.test(ext)) {
            return "assets/images/[name]-[hash][extname]";
          }
          if (/woff2?|ttf|eot/i.test(ext)) {
            return "assets/fonts/[name]-[hash][extname]";
          }
          return "assets/[name]-[hash][extname]";
        },

        entryFileNames: "assets/[name]-[hash].js",
      },
    },

    // Chunk size warnings (fail build if exceeded)
    chunkSizeWarningLimit: 500, // KB

    // Target modern browsers (ES2020)
    target: ["es2020", "edge88", "firefox78", "chrome87", "safari14"],

    // CSS code splitting
    cssCodeSplit: true,
  },

  // Preview server (for testing dist/ locally)
  preview: {
    port: 4173,
    strictPort: true,
  },

  // Optimization hints
  optimizeDeps: {
    include: ["react", "react-dom", "minisearch"],
    exclude: ["@vite/client", "@vite/env"],
  },
}));

2.2 Environment-Specific Configuration​

Build behavior varies by environment:

// scripts/build-production.js
import { build } from "vite";
import { loadEnv } from "vite";

const ENV_CONFIGS = {
  development: {
    sourcemap: true,
    minify: false,
    terserOptions: {},
  },
  staging: {
    sourcemap: "hidden", // Source maps for debugging, not public
    minify: "terser",
    terserOptions: {
      compress: { drop_console: false },
    },
  },
  production: {
    sourcemap: false,
    minify: "terser",
    terserOptions: {
      compress: { drop_console: true, pure_funcs: ["console.log"] },
    },
  },
};

export async function buildForEnvironment(env = "production") {
  const config = ENV_CONFIGS[env];
  const envVars = loadEnv(env, process.cwd(), "");

  await build({
    mode: env,
    build: config,
    define: {
      __APP_ENV__: JSON.stringify(env),
      __BUILD_TIME__: JSON.stringify(new Date().toISOString()),
    },
  });
}

3. Markdown-to-HTML Build-Time Conversion​

3.1 Strategy​

Current: Markdown loaded via fetch() at runtime, parsed client-side with unified. Optimization: Pre-convert to HTML at build time, embed in publish.json manifest.

3.2 Pre-Build Processing Script​

// scripts/preprocess-markdown.js
import { readFileSync, writeFileSync } from "fs";
import { unified } from "unified";
import remarkParse from "remark-parse";
import remarkGfm from "remark-gfm";
import remarkMath from "remark-math";
import remarkFrontmatter from "remark-frontmatter";
import remarkRehype from "remark-rehype";
import rehypeRaw from "rehype-raw";
import rehypeHighlight from "rehype-highlight";
import rehypeKatex from "rehype-katex";
import rehypeSlug from "rehype-slug";
import rehypeAutolinkHeadings from "rehype-autolink-headings";
import rehypeStringify from "rehype-stringify";
import matter from "gray-matter";
import { glob } from "glob";

/**
 * A.4.2: Pre-render all markdown documents to optimized HTML.
 * Embeds rendered HTML into publish.json manifest to avoid runtime parsing.
 */

const processor = unified()
  .use(remarkParse)
  .use(remarkFrontmatter, ["yaml"])
  .use(remarkGfm)
  .use(remarkMath)
  .use(remarkRehype, { allowDangerousHtml: true })
  .use(rehypeRaw)
  .use(rehypeHighlight, { subset: ["javascript", "python", "bash", "json", "yaml", "sql"] })
  .use(rehypeKatex)
  .use(rehypeSlug)
  .use(rehypeAutolinkHeadings, { behavior: "wrap" })
  .use(rehypeStringify);

async function preprocessMarkdownFiles() {
  const markdownFiles = glob.sync("**/*.md", {
    cwd: process.cwd(),
    ignore: ["node_modules/**", "dist/**", ".coditect/**", "CLAUDE.md"],
  });

  const processedDocs = [];

  for (const file of markdownFiles) {
    const content = readFileSync(file, "utf-8");
    const { data: frontmatter, content: markdown } = matter(content);

    // Render to HTML
    const rendered = await processor.process(markdown);
    const html = String(rendered);

    // Extract headings for TOC
    const headings = extractHeadings(html);

    processedDocs.push({
      id: file.replace(/\.md$/, "").replace(/\//g, "-"),
      path: file,
      title: frontmatter.title || titleFromFilename(file),
      html, // Pre-rendered HTML
      frontmatter,
      headings,
      wordCount: markdown.split(/\s+/).length,
      estimatedReadTime: Math.ceil(markdown.split(/\s+/).length / 200), // 200 WPM
    });
  }

  // Write enhanced manifest
  const manifest = {
    version: "1.0.0",
    generated_at: new Date().toISOString(),
    build_mode: "prerendered",
    total_documents: processedDocs.length,
    documents: processedDocs,
  };

  writeFileSync("public/publish.json", JSON.stringify(manifest, null, 2));
  console.log(`✅ Pre-rendered ${processedDocs.length} documents to publish.json`);
}

function extractHeadings(html) {
  const regex = /<h([1-6])[^>]*id="([^"]+)"[^>]*>(.*?)<\/h\1>/g;
  const headings = [];
  let match;

  while ((match = regex.exec(html)) !== null) {
    headings.push({
      level: parseInt(match[1]),
      id: match[2],
      text: match[3].replace(/<[^>]+>/g, ""), // Strip inner tags
    });
  }

  return headings;
}

function titleFromFilename(file) {
  return file
    .split("/")
    .pop()
    .replace(/\.md$/, "")
    .replace(/^\d+-/, "")
    .replace(/-/g, " ")
    .replace(/\b\w/g, (c) => c.toUpperCase());
}

preprocessMarkdownFiles().catch(console.error);

3.3 Runtime Optimization​

With pre-rendered HTML, MarkdownRenderer.jsx becomes trivial:

// components/MarkdownRenderer.jsx (OPTIMIZED)
import React, { useEffect } from "react";

export default function MarkdownRenderer({ html, onHeadingsExtracted }) {
  useEffect(() => {
    // Extract headings from pre-rendered HTML for TOC
    const headings = Array.from(document.querySelectorAll(".markdown-content h1, .markdown-content h2, .markdown-content h3, .markdown-content h4"))
      .map((el) => ({
        level: parseInt(el.tagName[1]),
        id: el.id,
        text: el.textContent,
      }));
    onHeadingsExtracted?.(headings);
  }, [html, onHeadingsExtracted]);

  return (
    <article
      className="markdown-content prose dark:prose-invert max-w-none"
      dangerouslySetInnerHTML={{ __html: html }}
    />
  );
}

Savings:

  • Eliminates unified + 8 remark/rehype plugins from client bundle (~280KB unminified)
  • Removes runtime parsing overhead (100-300ms per document)
  • First Contentful Paint improves by ~400ms

4. Asset Pipeline​

4.1 Image Optimization​

// vite.config.js additions
import viteImagemin from "vite-plugin-imagemin";

plugins: [
  viteImagemin({
    gifsicle: { optimizationLevel: 7, interlaced: false },
    optipng: { optimizationLevel: 7 },
    mozjpeg: { quality: 80 },
    pngquant: { quality: [0.8, 0.9], speed: 4 },
    svgo: {
      plugins: [
        { name: "removeViewBox", active: false },
        { name: "removeEmptyAttrs", active: true },
      ],
    },
  }),
],

4.2 Font Subsetting​

The logo uses system fonts, but if custom fonts are added:

// scripts/subset-fonts.js (future use)
import { subset } from "subset-font";

const LATIN_CHARS = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789.,;:!?'-() ";

async function subsetFont(inputPath, outputPath) {
  const font = readFileSync(inputPath);
  const subsetted = await subset(font, LATIN_CHARS);
  writeFileSync(outputPath, subsetted);
}

4.3 KaTeX CSS Optimization​

KaTeX includes 23KB of CSS for math rendering. Purge unused selectors:

// postcss.config.cjs
module.exports = {
  plugins: {
    "postcss-import": {},
    tailwindcss: {},
    autoprefixer: {},
    ...(process.env.NODE_ENV === "production" && {
      cssnano: {
        preset: ["default", { discardComments: { removeAll: true } }],
      },
      "@fullhuman/postcss-purgecss": {
        content: ["./index.html", "./viewer.jsx", "./components/**/*.jsx", "./dashboards/**/*.jsx"],
        safelist: [/^katex/, /^hljs-/, /^language-/, /^mermaid/],
      },
    }),
  },
};

5. Code Splitting Strategy​

5.1 Dashboard Lazy Loading​

Current implementation (viewer.jsx lines 26-54) already uses React.lazy(). Vite automatically chunks:

const dashboardModules = {
  "dashboards-system-32-tech-architecture-analyzer": lazy(() =>
    import("./dashboards/system/32-tech-architecture-analyzer.jsx")
  ),
  // ... 27 more
};

Vite Output:

dist/assets/dashboard-system-32-tech-architecture-analyzer-a3f7b9e2.js  (45.2 KB)
dist/assets/dashboard-system-33-wo-unified-system-dashboard-d8c1e432.js (42.8 KB)
dist/assets/dashboard-system-34-wo-state-machine-visualizer-e7f3a91b.js (38.6 KB)
...

5.2 Component-Level Splitting​

Split heavy components from main bundle:

// viewer.jsx modifications
import { lazy } from "react";

// Defer markdown renderer (65KB) until first doc view
const MarkdownRenderer = lazy(() => import("./components/MarkdownRenderer.jsx"));

// Defer presentation mode (12KB) until activated
const PresentationMode = lazy(() => import("./components/PresentationMode.jsx"));

// Search loaded eagerly (needed for keyboard shortcut)
import SearchPanel from "./components/SearchPanel.jsx";

5.3 Route-Based Splitting​

Vite's manualChunks (section 2.1) creates logical bundles:

ChunkContentsSize (Gzipped)
vendor.jsreact, react-dom~42 KB
markdown.jsunified + plugins~85 KB (eliminated with pre-rendering)
search.jsminisearch, gray-matter~28 KB
katex.jsKaTeX library~67 KB
highlight.jsHighlight.js core~18 KB
mermaid.jsMermaid diagrams~120 KB
icons.jslucide-react~15 KB
viewer.jsMain app logic~32 KB

Total Core Bundle: ~175 KB (gzipped) — loaded upfront. Deferred: Dashboards (28 × ~40KB avg) + Mermaid (120KB) = ~1240 KB — loaded on-demand.

6. Tree Shaking and Dead Code Elimination​

6.1 ES Module Discipline​

All imports use named exports for optimal tree shaking:

// BAD (imports entire library)
import _ from "lodash";
const result = _.uniq(array);

// GOOD (imports only uniq function)
import { uniq } from "lodash-es";
const result = uniq(array);

6.2 Vite Tree Shaking Analysis​

# Generate bundle analysis
npm run build -- --mode production
npx vite-bundle-visualizer

# Output: dist/stats.html (interactive treemap)

6.3 Unused Export Detection​

// scripts/detect-dead-code.js
import { analyzeMetafile } from "esbuild";
import { readFileSync } from "fs";

const metafile = JSON.parse(readFileSync("dist/metafile.json", "utf-8"));
const analysis = await analyzeMetafile(metafile);

console.log(analysis);
// Shows which exports are unused and can be removed

7. Bundle Size Optimization​

7.1 Compression Strategy​

Dual compression (Gzip + Brotli) for CDN flexibility:

// vite.config.js
import compression from "vite-plugin-compression";

plugins: [
  compression({
    algorithm: "gzip",
    ext: ".gz",
    threshold: 10240, // Only compress files > 10KB
    deleteOriginFile: false,
  }),
  compression({
    algorithm: "brotliCompress",
    ext: ".br",
    threshold: 10240,
    compressionOptions: { level: 11 }, // Max compression
    deleteOriginFile: false,
  }),
],

Nginx/CDN Configuration:

# nginx.conf (for self-hosted deployments)
gzip_static on;
brotli_static on;

location ~* \.(?:js|css|svg|woff2)$ {
  expires 1y;
  add_header Cache-Control "public, immutable";
}

7.2 Minification Settings​

Terser configuration (more aggressive than esbuild default):

terserOptions: {
  compress: {
    drop_console: true,        // Remove console.log
    drop_debugger: true,        // Remove debugger statements
    pure_funcs: ["console.log", "console.info", "console.debug"],
    passes: 2,                  // Two-pass compression
    unsafe: true,               // Aggressive optimizations
    unsafe_comps: true,
    unsafe_math: true,
    unsafe_proto: true,
  },
  mangle: {
    safari10: true,             // Safari 10 compatibility
  },
  format: {
    comments: false,            // Strip all comments
  },
},

7.3 CSS Optimization​

// postcss.config.cjs
module.exports = {
  plugins: {
    tailwindcss: {},
    autoprefixer: {},
    cssnano: {
      preset: [
        "advanced",
        {
          discardComments: { removeAll: true },
          reduceIdents: true,
          mergeRules: true,
          minifySelectors: true,
          normalizeWhitespace: true,
        },
      ],
    },
  },
};

7.4 Dynamic Import Optimization​

Prefetch critical routes:

// viewer.jsx
useEffect(() => {
  // Prefetch likely-next dashboards on idle
  if ("requestIdleCallback" in window) {
    requestIdleCallback(() => {
      import("./dashboards/system/32-tech-architecture-analyzer.jsx");
      import("./dashboards/planning/60-project-command-center.jsx");
    });
  }
}, []);

8. Build Output Structure​

9.2 Manifest Generation Integration​

// package.json
{
  "scripts": {
    "prebuild": "node scripts/preprocess-markdown.js",
    "build": "npm run prebuild && vite build",
    "postbuild": "node scripts/verify-size-budget.js"
  }
}

10. Search Index Pre-Generation​

10.1 Build-Time Indexing​

// scripts/generate-search-index.js
import MiniSearch from "minisearch";
import { readFileSync, writeFileSync } from "fs";

/**
 * A.4.2: Pre-generate MiniSearch index at build time.
 * Eliminates 300-500ms client-side indexing delay.
 */

async function generateSearchIndex() {
  const manifest = JSON.parse(readFileSync("public/publish.json", "utf-8"));

  const miniSearch = new MiniSearch({
    fields: ["title", "content", "category"],
    storeFields: ["id", "title", "path", "category", "type"],
    searchOptions: {
      boost: { title: 3, content: 1 },
      fuzzy: 0.2,
      prefix: true,
    },
  });

  const documents = manifest.documents.map((doc) => ({
    id: doc.id,
    title: doc.title,
    category: doc.category,
    type: doc.type,
    path: doc.path,
    content: stripHtml(doc.html), // Plain text for indexing
  }));

  miniSearch.addAll(documents);

  // Serialize to JSON
  const indexData = JSON.stringify(miniSearch.toJSON());
  writeFileSync("public/search-index.json", indexData);

  console.log(`✅ Generated search index: ${documents.length} documents, ${(indexData.length / 1024).toFixed(1)} KB`);
}

function stripHtml(html) {
  return html
    .replace(/<[^>]+>/g, " ")
    .replace(/\s+/g, " ")
    .trim();
}

generateSearchIndex().catch(console.error);

10.2 Client-Side Index Loading​

// components/SearchPanel.jsx (OPTIMIZED)
import MiniSearch from "minisearch";
import { useState, useEffect } from "react";

let searchIndex = null;

export async function initSearch() {
  if (searchIndex) return searchIndex;

  // Load pre-built index
  const resp = await fetch("/search-index.json");
  const indexData = await resp.json();

  searchIndex = MiniSearch.loadJSON(indexData, {
    fields: ["title", "content", "category"],
    storeFields: ["id", "title", "path", "category", "type"],
  });

  return searchIndex;
}

export default function SearchPanel({ onNavigate }) {
  const [results, setResults] = useState([]);
  const [isReady, setIsReady] = useState(false);

  useEffect(() => {
    initSearch().then(() => setIsReady(true));
  }, []);

  const handleSearch = (query) => {
    if (!searchIndex || !query.trim()) {
      setResults([]);
      return;
    }

    const hits = searchIndex.search(query, { limit: 20 });
    setResults(hits);
  };

  return (
    <div>
      <input
        type="search"
        placeholder={isReady ? "Search documents..." : "Loading index..."}
        onChange={(e) => handleSearch(e.target.value)}
        disabled={!isReady}
      />
      {/* ... results rendering ... */}
    </div>
  );
}

Performance Impact:

  • Runtime indexing: 300-500ms on page load
  • Pre-built index: 420 KB download, 50ms deserialization
  • Net savings: ~400ms faster Time to Interactive

11. Build Performance Targets​

11.1 Target Metrics​

MetricTargetMeasurement
Full Build (Cold)< 60stime npm run build
Incremental Build< 10stime npm run build (after code change)
Markdown Pre-Processing< 15sScript execution time (99 files)
Search Index Generation< 5sScript execution time
Bundle Analysis< 8sRollup plugin execution
Compression (Gzip + Brotli)< 12sPlugin execution time
Total CI Build Time< 90sGitHub Actions pipeline

11.2 Optimization Techniques​

// scripts/parallel-markdown-processing.js
import { Worker } from "worker_threads";
import os from "os";

const WORKERS = os.cpus().length;

async function processMarkdownInParallel(files) {
  const chunks = chunkArray(files, Math.ceil(files.length / WORKERS));

  const workers = chunks.map((chunk) => {
    return new Promise((resolve, reject) => {
      const worker = new Worker("./worker-markdown.js", {
        workerData: { files: chunk },
      });
      worker.on("message", resolve);
      worker.on("error", reject);
    });
  });

  const results = await Promise.all(workers);
  return results.flat();
}

function chunkArray(arr, size) {
  return Array.from({ length: Math.ceil(arr.length / size) }, (_, i) =>
    arr.slice(i * size, (i + 1) * size)
  );
}

11.3 Caching Strategy​

// vite.config.js
export default defineConfig({
  cacheDir: "node_modules/.vite",
  build: {
    cache: {
      type: "filesystem",
      cacheDirectory: ".vite-cache",
    },
  },
});

12. CI Integration​

12.2 Build Artifact Verification​

// scripts/verify-build-integrity.js
import { createHash } from "crypto";
import { readFileSync, writeFileSync, readdirSync } from "fs";
import { join } from "path";

/**
 * A.4.2: Verify build integrity with SHA-256 checksums.

 */

function generateChecksums(dir) {
  const checksums = {};

  function walk(currentDir) {

const checksums = generateChecksums("dist");
writeFileSync("dist/checksums.json", JSON.stringify(checksums, null, 2));

console.log(`✅ Generated checksums for ${Object.keys(checksums).length} files`);

13. Size Budget Enforcement​

13.1 Automated Size Check​

// scripts/verify-size-budget.js
import { statSync, readdirSync } from "fs";
import { join } from "path";

const SIZE_BUDGET_MB = 5.0;
const SIZE_BUDGET_BYTES = SIZE_BUDGET_MB * 1024 * 1024;

/**

 * Fails build if exceeded.
 */

function calculateDirectorySize(dir, extensions = [".gz"]) {
  let total = 0;

  function walk(currentDir) {
    for (const entry of readdirSync(currentDir, { withFileTypes: true })) {
      const fullPath = join(currentDir, entry.name);

      if (entry.isDirectory()) {
        walk(fullPath);
      } else if (entry.isFile() && extensions.some((ext) => entry.name.endsWith(ext))) {
        total += statSync(fullPath).size;
      }
    }
  }

  walk(dir);
  return total;
}

const gzippedSize = calculateDirectorySize("dist", [".gz"]);
const sizeInMB = gzippedSize / 1024 / 1024;
const utilization = (gzippedSize / SIZE_BUDGET_BYTES) * 100;

console.log(`\n📊 Size Budget Report:`);
console.log(`   Total (gzipped): ${sizeInMB.toFixed(2)} MB`);
console.log(`   Budget: ${SIZE_BUDGET_MB} MB`);
console.log(`   Utilization: ${utilization.toFixed(1)}%`);

if (gzippedSize > SIZE_BUDGET_BYTES) {
  console.error(`\n❌ Size budget exceeded by ${(sizeInMB - SIZE_BUDGET_MB).toFixed(2)} MB`);
  process.exit(1);
}

console.log(`\n✅ Size budget passed with ${(SIZE_BUDGET_MB - sizeInMB).toFixed(2)} MB remaining\n`);

13.2 Per-Chunk Budget​

// scripts/verify-chunk-sizes.js
import { statSync, readdirSync } from "fs";
import { join } from "path";

const CHUNK_BUDGETS = {
  vendor: 50 * 1024,        // 50 KB gzipped

        if (regex.test(asset) && size > budget) {
          failures.push({ asset, size, budget });
        }
      } else if (asset.startsWith(pattern) && size > budget) {
        failures.push({ asset, size, budget });
      }
    }
  }

  if (failures.length > 0) {
    console.error("\n❌ Chunk size budget exceeded:");
    failures.forEach(({ asset, size, budget }) => {
      console.error(`   ${asset}: ${(size / 1024).toFixed(1)} KB (budget: ${(budget / 1024).toFixed(1)} KB)`);
    });
    process.exit(1);
  }

  console.log("✅ All chunks within budget");

18. Deployment Integration​

18.1 CDN Deployment (Google Cloud Storage)​

// scripts/deploy-to-cdn.js
import { Storage } from "@google-cloud/storage";
import { readdirSync, readFileSync, statSync } from "fs";
import { join } from "path";
import { lookup } from "mime-types";

/**
 * A.4.2: Deploy dist/ to GCS with optimal caching headers.
 */

20.2 Service Worker Implementation (Planned)​

// public/service-worker.js (future implementation)
const CACHE_VERSION = "v1.0.0";
const STATIC_CACHE = `bio-qms-static-${CACHE_VERSION}`;
const DYNAMIC_CACHE = `bio-qms-dynamic-${CACHE_VERSION}`;

const STATIC_ASSETS = [
  "/",
  "/index.html",
  "/assets/vendor.js",
  "/assets/viewer.js",
  "/assets/styles.css",
  "/coditect-logo.png",
];

self.addEventListener("install", (event) => {
  event.waitUntil(
    caches.open(STATIC_CACHE).then((cache) => cache.addAll(STATIC_ASSETS))
  );
});

self.addEventListener("fetch", (event) => {
  event.respondWith(
    caches.match(event.request).then((response) => {
      return response || fetch(event.request).then((fetchResponse) => {
        return caches.open(DYNAMIC_CACHE).then((cache) => {
          cache.put(event.request, fetchResponse.clone());
          return fetchResponse;
        });
      });
    })
  );
});
