useAttributeTranslations

Description

The useAttributeTranslations composable is responsible for fetching and managing product attribute translations based on the current locale in a Nuxt-based e-commerce application. It ensures that the correct translations are loaded either from a local cache or by fetching them from a CDN. The composable also manages language change events by watching the locale and reloading the translations when the language changes. It helps in providing localized product attribute information for a seamless user experience across different languages.

FEATURE GOALS

• Fetch and manage product attribute translations based on the current locale.
• Utilize a local cache (product store) to minimize unnecessary requests.
• Load translations from a CDN when necessary.
• Ensure translations are automatically updated when the locale changes.
• Provide error handling for any failures in the translation fetching process.

FEATURE EXPECTATIONS

• Translations are fetched from either a local cache or a CDN based on the current locale.
• Locale changes trigger a re-fetch of translations.
• The composable gracefully handles errors during the fetch process and logs them for debugging.
• Caching is used to prevent repeated fetching of the same data for the same locale.

DEV STRATEGIES

1. Composables Logic

const { translations, fetchTranslations } = useAttributeTranslations();

// Fetch translations manually
await fetchTranslations();

// Translations will be available as `translations.value`
console.log(translations.value);

• Translations are fetched based on the current locale, and the fetched data is stored in the translations reference.
• The translations are cached using the productStore to prevent unnecessary network requests.
• The locale is watched, and if it changes, the translations are automatically re-fetched for the new language.

2. COMPOSABLE STRUCTURE

useAttributeTranslations(): {
  translations: Ref<Record<string, string>>; 
  fetchTranslations: () => Promise<void>;
}

3. DEFAULT BEHAVIOR

4. ERROR RESPONSE STRUCTURE

• If there is an error fetching the translations, the composable handles it and calls a custom error handler:

{
  success: false,
  error: string // Describes the error that occurred during the translation fetch
}

• The error details are logged with contextual information (e.g., cacheKey, locale).

FLOW SUMMARY

• The composable first checks if translations for the current locale are available in the local cache (productStore).
• If not found, it fetches the translations from a CDN.
• When the locale changes, translations are automatically re-fetched for the new language.
• If fetching fails, the error is logged using a custom error handler.
• The composable uses a reactive reference (translations) to store the fetched translations and make them available for use within the application.
