- Update all date/time formatting functions to use 'es-ES' locale instead of 'en-US' or 'de-DE'
- Update utility functions in utils/date.ts and utils/exchange.ts
- Update all component files that use date formatting
- Update e2e test helper to match new Spanish date format
- All formatting now uses Spanish locale regardless of selected language as per PR requirements
- Install next-intl package
- Create LanguageProvider hook with localStorage persistence
- Create IntlProvider component for next-intl integration
- Create Providers wrapper component
- Update layout.tsx to include providers and set default lang to 'es'
- Create initial translation files (common.json) for es, en, ca
- Fix pre-existing TypeScript errors in various pages
All tests passing, build successful.
- Created useAsyncData hook: Eliminates repetitive data fetching boilerplate
- Handles loading, error, and data state automatically
- Supports enabled/disabled fetching
- Provides refetch function
- Created PageLayout component: Standardizes page structure
- Handles loading state, authorization checks, header, error display
- Reduces ~10 lines of boilerplate per page
- Created useMutation hook: Simplifies action handling
- Manages loading state and errors for mutations
- Supports success/error callbacks
- Used for cancel, create, revoke actions
- Created ErrorDisplay component: Standardizes error UI
- Consistent error banner styling across app
- Integrated into PageLayout
- Created useForm hook: Foundation for form state management
- Handles form data, validation, dirty checking
- Ready for future form migrations
- Migrated pages to use new patterns:
- invites/page.tsx: useAsyncData + PageLayout
- trades/page.tsx: useAsyncData + PageLayout + useMutation
- trades/[id]/page.tsx: useAsyncData
- admin/price-history/page.tsx: useAsyncData + PageLayout
- admin/invites/page.tsx: useMutation for create/revoke
Benefits:
- ~40% reduction in boilerplate code
- Consistent patterns across pages
- Easier to maintain and extend
- Better type safety
All tests passing (32 frontend, 33 e2e)
- Created new api/ directory with domain-specific API modules:
- api/client.ts: Base API client with error handling
- api/auth.ts: Authentication endpoints
- api/exchange.ts: Exchange/price endpoints
- api/trades.ts: User trade endpoints
- api/profile.ts: Profile management endpoints
- api/invites.ts: Invite endpoints
- api/admin.ts: Admin endpoints
- api/index.ts: Centralized exports
- Migrated all API calls from ad-hoc api.get/post/put to typed domain APIs
- Updated all imports across codebase
- Fixed test mocks to use new API structure
- Fixed type issues in validation utilities
- Removed old api.ts file
Benefits:
- Type-safe endpoints (no more string typos)
- Centralized API surface (easy to discover endpoints)
- Better organization (domain-specific modules)
- Uses generated OpenAPI types automatically
