40.4 Internationalization schemas (multi-locale outputs)

Multi-Locale Schema

const LocalizedContent = z.object({
  localized: z.record(
    z.enum(['en', 'es', 'fr', 'de', 'ja']),
    z.object({
      title: z.string(),
      description: z.string(),
      keywords: z.array(z.string())
    })
  ),
  defaultLocale: z.enum(['en', 'es', 'fr', 'de', 'ja'])
});

// Example output
{
  "localized": {
    "en": { "title": "Welcome", "description": "...", "keywords": ["..."] },
    "es": { "title": "Bienvenido", "description": "...", "keywords": ["..."] }
  },
  "defaultLocale": "en"
}

Prompting

const I18N_PROMPT = `
Generate content for these locales: ${locales.join(', ')}

Rules:
- Translate, don't transliterate
- Adapt cultural references appropriately
- Keep technical terms consistent across locales
- Maintain same meaning and tone

Output localized content for each requested locale.
