feat: complete Phase 3 - Domain Modeling & Data Layer
Implements comprehensive type system, runtime validation, API client, and testing infrastructure for CS2.WTF. TypeScript Interfaces (src/lib/types/): - Match.ts: Match, MatchPlayer, MatchListItem types - Player.ts: Player, PlayerMeta, PlayerProfile types - RoundStats.ts: Round economy and performance data - Weapon.ts: Weapon statistics with hit groups (HitGroup, WeaponType enums) - Message.ts: Chat messages with filtering support - api.ts: API responses, errors, and APIException class - Complete type safety with strict null checks Zod Schemas (src/lib/schemas/): - Runtime validation for all data models - Schema parsers with safe/unsafe variants - Special handling for backend typo (looses → losses) - Share code validation regex - CS2-specific validations (rank 0-30000, MR12 rounds) API Client (src/lib/api/): - client.ts: Axios-based HTTP client with error handling - Request cancellation support (AbortController) - Automatic retry logic for transient failures - Timeout handling (10s default) - Typed APIException errors - players.ts: Player endpoints (profile, meta, track/untrack, search) - matches.ts: Match endpoints (parse, details, weapons, rounds, chat, search) - Zod validation on all API responses MSW Mock Handlers (src/mocks/): - fixtures.ts: Comprehensive mock data for testing - handlers/players.ts: Mock player API endpoints - handlers/matches.ts: Mock match API endpoints - browser.ts: Browser MSW worker for development - server.ts: Node MSW server for Vitest tests - Realistic responses with delays and pagination - Safe integer IDs to avoid precision loss Configuration: - .env.example: Complete environment variable documentation - src/vite-env.d.ts: Vite environment type definitions - All strict TypeScript checks passing (0 errors, 0 warnings) Features: - Cancellable requests for search (prevent race conditions) - Data normalization (backend typo handling) - Comprehensive error types (NetworkError, Timeout, etc.) - Share code parsing and validation - Pagination support for players and matches - Mock data for offline development and testing Build Status: ✓ Production build successful Type Check: ✓ 0 errors, 0 warnings Lint: ✓ All checks passed Phase 3 Completion: 100% 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
