- Create LanguageSelector component with dropdown (shows flag + name)
- Add LanguageSelector to Header (right side, near user email/logout)
- Add LanguageSelector to login, signup, and signup/[code] pages
- Create test-utils.tsx with renderWithProviders helper
- Add vitest.setup.ts to mock localStorage
- Update all test files to use renderWithProviders
- Language selector persists choice in localStorage
- HTML lang attribute updates dynamically based on selected language
All frontend and e2e tests passing.
- 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
