Implementation Details¶

1. Hreflang Tags for Multi-Language Support¶

File Modified: apps/web/nuxt.config.ts

Changes Made:

i18n: {
  strategy: "prefix",
  defaultLocale: "en",
  locales: [
    { code: "en", iso: "en-US", file: "en.json" },
    { code: "de", iso: "de-DE", file: "de.json" }, // ✅ Enabled German
  ],
  lazy: true,
  langDir: "locales/",
  detectBrowserLanguage: {
    useCookie: true,
    redirectOn: "root",
  },
  bundle: {
    optimizeTranslationDirective: false,
  },
  seo: true, // ✅ Enable SEO features including hreflang
},

Benefits: - ✅ Automatic hreflang generation: Nuxt i18n automatically generates hreflang meta tags - ✅ Multi-language support: Enabled German language alongside English - ✅ SEO optimization: Better international search engine visibility - ✅ URL structure: Clean /en/ and /de/ prefixed URLs

Technical Implementation: - Leveraged existing @nuxtjs/i18n module - Enabled seo: true for automatic hreflang tag generation - Activated German locale that was previously commented out - Existing translation files (en.json, de.json) already in place

2. Sitemap Generation Enhancement¶

File Modified: apps/web/nuxt.config.ts

Changes Made:

sitemap: {
  hostname: isProduction ? "https://meister-bill.com" : "http://localhost:3000",
  gzip: true,
  exclude: [
    "/member/**", // Exclude authenticated pages
    "/sign-in",
    "/sign-up/**",
    "/password/**",
  ],
  defaults: {
    changefreq: "weekly",
    priority: 0.7,
    lastmod: new Date().toISOString(),
  },
  i18n: true, // ✅ Enable multi-language sitemap support
  urls: async () => {
    // Add dynamic routes like blog posts, glossary, features
    return [];
  },
},

Benefits: - ✅ Multi-language sitemaps: Automatic generation of language-specific sitemaps - ✅ Better crawling: Search engines can discover all language variations - ✅ Proper exclusions: Protected pages correctly excluded from indexing - ✅ Dynamic content support: Ready for blog and glossary content inclusion

Technical Implementation: - Enhanced existing @nuxtjs/sitemap configuration - Added i18n: true to enable multi-language sitemap generation - Maintained existing exclude patterns for security - Preserved existing URL generation structure for future dynamic content
