Frontend Development Progress - Agent 2

Session Date: May 16, 2026
Agent: Frontend Specialist (Agent 2)
Status: Phase 1 - Foundation Complete

Completed Work (Week 1)

Infrastructure & Setup ✅

• Created comprehensive TypeScript type definitions (src/types/game.ts)
• Set up 4 context providers:
  • AuthContext - User authentication, JWT token management
  • GameContext - Game state with reducer pattern, card management
  • ThemeContext - Theme switching (Light/Dark/Neon), localStorage
  • WebSocketContext - Socket.io wrapper for real-time sync

API & Utilities ✅

• src/lib/api.ts - Fetch wrapper with timeout, auth headers, all REST endpoints
• src/lib/socket.ts - Socket.io initialization, reconnection, event handling
• src/lib/chess.ts - chess.js wrapper (move validation, legal moves, check/checkmate)
• src/lib/constants.ts - Card definitions, theme colors, API URLs

Pages Implemented ✅

• Homepage (/) - 3 game mode buttons, auth buttons
• Login (/auth/login) - Email/password form with validation
• Register (/auth/register) - Registration with password requirements
• Lobby (/lobby) - Create/join online rooms
• Game Pages (/game/[gameId], /game/local, /game/computer)

Architecture Decisions

• Context API (simpler than Redux for this scale)
• FEN notation for board state
• Optimistic updates pattern
• httpOnly cookies for JWT (secure, backend-managed)

Storybook Setup ✅ (Phase 1B - Design Testing)

• Configured Storybook 10.4.0 for Next.js
• Created reusable component library:
  • Button - 4 variants (primary, secondary, danger, success), 3 sizes
  • Card - Simple container with optional title
  • Input - Form field with label and error state
  • PowerCard - All 8 card types with unique colors and click handlers
  • ChessBoard - 8x8 interactive board with FEN support, legal move highlighting
• Created 25+ stories covering all component variants and states
• Added dark/light mode support with Tailwind CSS
• Documentation: STORYBOOK.md
