Created centralized helpers:
- src/lib/i18n/pageMetadata.ts: All page metadata (titles, descriptions, alt text)
- src/lib/i18n/productText.ts: Product-specific translated text (shortDescription, benefits)
- src/lib/i18n/metadata.ts: Helper functions for locale handling
Updated all pages to use centralized metadata:
- Homepage: Uses getPageMetadata for title, description, productionAlt
- Products page: Uses getPageMetadata
- Product detail: Uses getPageMetadata + getTranslatedShortDescription/getTranslatedBenefits
- About page: Uses getPageMetadata
ProductDetail component now uses:
- getTranslatedShortDescription() instead of locale comparison
- getTranslatedBenefits() instead of locale comparison
All user-facing text now goes through translation files or centralized helpers.
Adding a new language now requires only:
1. Add to SUPPORTED_LOCALES in locales.ts
2. Add LOCALE_CONFIG entry
3. Add entries to pageMetadata.ts and productText.ts
4. Add translation keys to message files
- Added src/lib/i18n/metadata.ts with helper functions
- Updated [locale]/layout.tsx to use DEFAULT_LOCALE constant
- routing.ts already uses centralized SUPPORTED_LOCALES
Note: For full antifragility, a larger refactor would centralize
all hardcoded locale comparisons for metadata text fallbacks.
Currently adding a new language requires:
1. SUPPORTED_LOCALES in locales.ts
2. LOCALE_CONFIG entry
3. Translation keys in all message files
- Added getPathWithoutLocale() and buildLocalePath() helpers to locales.ts
- Updated Header to use centralized helpers instead of hardcoded regex
- Updated middleware to use SUPPORTED_LOCALES in matcher config
- Updated LocaleProvider to use isValidLocale() instead of hardcoded array
To add a new language now, only update:
1. SUPPORTED_LOCALES in locales.ts
2. LOCALE_CONFIG entry with label, flag, saleorLocale
3. Add translation keys to all message files
All routing now uses centralized constants - no more hardcoded locale lists.
Created src/lib/i18n/locales.ts as single source of truth for:
- SUPPORTED_LOCALES array
- LOCALE_COOKIE name
- DEFAULT_LOCALE
- LOCALE_CONFIG (labels, flags, Saleor locale mapping)
- Helper functions (isValidLocale, getSaleorLocale, getLocaleFromPath)
Updated all files to use centralized constants:
- middleware.ts
- Header.tsx
- ProductCard.tsx
- sitemap.ts
- root layout and locale layout
- routing.ts
Benefits:
- Adding new locale only requires updating ONE file (locales.ts)
- No more hardcoded locale lists scattered across codebase
- Cookie name defined in one place
- Type-safe locale validation
