Phase 01 Plan 01: FastAPI Backend Foundation Summary

FastAPI backend initialized with uv package manager, pydantic-settings configuration, and health endpoints at /health and /api/v1/health

Performance

• Duration: 3 min
• Started: 2026-01-25T20:06:07Z
• Completed: 2026-01-25T20:09:42Z
• Tasks: 2
• Files modified: 13

Accomplishments

• Initialized Python project with uv package manager and all required dependencies
• Created FastAPI application with production-ready configuration management
• Implemented health check endpoints with readiness probe placeholder
• Configured ruff linter passing on all code

Task Commits

Each task was committed atomically:

1. Task 1: Initialize Python project with uv and dependencies - 300b3dd (feat)
2. Task 2: Create FastAPI application structure with health endpoint - 519333e (feat)

Files Created/Modified

• pyproject.toml - Project configuration with dependencies, ruff, and mypy settings
• .env.example - Documented environment variables template
• README.md - Basic development setup instructions
• backend/app/main.py - FastAPI application entry point with root health check
• backend/app/core/config.py - pydantic-settings configuration with environment parsing
• backend/app/api/v1/router.py - API v1 router including health endpoints
• backend/app/api/v1/endpoints/health.py - Health and readiness check endpoints

Decisions Made

• Used hatchling as build backend (standard for modern Python projects)
• Created root /health endpoint outside versioned API for simpler health checks
• Used pydantic-settings model_config approach (Pydantic v2 style) for configuration
• Configured comprehensive ruff rule sets: E (errors), F (pyflakes), I (isort), N (naming), W (warnings), UP (upgrades)

Deviations from Plan

None - plan executed exactly as written.

Issues Encountered

• uv was not installed initially - installed via curl script (expected for fresh environment)
• hatchling required README.md to exist - created minimal README.md file
• hatchling needed explicit package path - added [tool.hatch.build.targets.wheel] configuration

User Setup Required

None - no external service configuration required.

Next Phase Readiness

• FastAPI application structure is complete and verified
• Ready for Plan 01-02: PostgreSQL database setup and connection pooling
• Configuration management is in place for database URL and other settings
