From fc7f53adf3e2ca87405cd8f822010d95ee7f3b69 Mon Sep 17 00:00:00 2001 From: Cal Corum Date: Tue, 21 Oct 2025 19:46:16 -0500 Subject: [PATCH] CLAUDE: Complete Phase 1 backend infrastructure setup MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implemented full FastAPI backend with WebSocket support, database models, and comprehensive documentation for the Paper Dynasty game engine. Backend Implementation: - FastAPI application with Socket.io WebSocket server - SQLAlchemy async database models (Game, Play, Lineup, GameSession) - PostgreSQL connection to dev server (10.10.0.42:5432) - Connection manager for WebSocket lifecycle - JWT authentication utilities - Health check and stub API endpoints - Rotating file logger with Pendulum datetime handling - Redis via Docker Compose for caching Technical Details: - Python 3.13 with updated package versions - Pendulum 3.0 for all datetime operations - Greenlet for SQLAlchemy async support - Fixed SQLAlchemy reserved column names (metadata -> *_metadata) - Pydantic Settings with JSON array format for lists - Docker Compose V2 commands Documentation: - Updated backend/CLAUDE.md with environment-specific details - Created .claude/ENVIRONMENT.md for gotchas and quirks - Created QUICKSTART.md for developer onboarding - Documented all critical learnings and troubleshooting steps Database: - Tables created: games, plays, lineups, game_sessions - All indexes and foreign keys configured - Successfully tested connection and health checks Verified: - Server starts at http://localhost:8000 - Health endpoints responding - Database connection working - WebSocket infrastructure functional - Hot-reload working 🎯 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- .claude/ENVIRONMENT.md | 235 ++++++++++++++++++++ QUICKSTART.md | 207 +++++++++++++++++ backend/.env.example | 25 +++ backend/CLAUDE.md | 138 +++++++++++- backend/app/__init__.py | 0 backend/app/api/__init__.py | 0 backend/app/api/routes/__init__.py | 0 backend/app/api/routes/auth.py | 56 +++++ backend/app/api/routes/games.py | 50 +++++ backend/app/api/routes/health.py | 46 ++++ backend/app/config.py | 48 ++++ backend/app/database/__init__.py | 0 backend/app/database/session.py | 54 +++++ backend/app/main.py | 82 +++++++ backend/app/models/__init__.py | 0 backend/app/models/db_models.py | 81 +++++++ backend/app/utils/__init__.py | 0 backend/app/utils/auth.py | 49 ++++ backend/app/utils/logging.py | 47 ++++ backend/app/websocket/__init__.py | 0 backend/app/websocket/connection_manager.py | 80 +++++++ backend/app/websocket/handlers.py | 91 ++++++++ backend/docker-compose.yml | 13 ++ backend/requirements-dev.txt | 7 + backend/requirements.txt | 18 ++ 25 files changed, 1322 insertions(+), 5 deletions(-) create mode 100644 .claude/ENVIRONMENT.md create mode 100644 QUICKSTART.md create mode 100644 backend/.env.example create mode 100644 backend/app/__init__.py create mode 100644 backend/app/api/__init__.py create mode 100644 backend/app/api/routes/__init__.py create mode 100644 backend/app/api/routes/auth.py create mode 100644 backend/app/api/routes/games.py create mode 100644 backend/app/api/routes/health.py create mode 100644 backend/app/config.py create mode 100644 backend/app/database/__init__.py create mode 100644 backend/app/database/session.py create mode 100644 backend/app/main.py create mode 100644 backend/app/models/__init__.py create mode 100644 backend/app/models/db_models.py create mode 100644 backend/app/utils/__init__.py create mode 100644 backend/app/utils/auth.py create mode 100644 backend/app/utils/logging.py create mode 100644 backend/app/websocket/__init__.py create mode 100644 backend/app/websocket/connection_manager.py create mode 100644 backend/app/websocket/handlers.py create mode 100644 backend/docker-compose.yml create mode 100644 backend/requirements-dev.txt create mode 100644 backend/requirements.txt diff --git a/.claude/ENVIRONMENT.md b/.claude/ENVIRONMENT.md new file mode 100644 index 0000000..6864814 --- /dev/null +++ b/.claude/ENVIRONMENT.md @@ -0,0 +1,235 @@ +# Environment-Specific Details & Gotchas + +**Last Updated**: 2025-10-21 + +This document contains critical environment-specific configurations and common pitfalls to avoid. + +## System Information + +- **OS**: Linux (Nobara Fedora 42) +- **Python**: 3.13.3 +- **Docker**: Compose V2 (use `docker compose` not `docker-compose`) +- **Database Server**: 10.10.0.42:5432 (PostgreSQL) + +## Critical Gotchas + +### 1.
