Python Backend Pack

Python Backend Pack

A curated bundle of essential skills for building Python backend services — from project structure through API, database, caching, and CLI.

What's Included

• fastapi-patterns — Production FastAPI applications with async patterns, dependency injection, and Pydantic models
• python-packaging-patterns — Project structure, pyproject.toml, dependency management, and distribution
• database-migration-patterns — Safe schema evolution with Alembic, zero-downtime strategies, and rollback
• cli-tool-design — Command-line interfaces with Typer/Click, subcommands, and shell completion
• redis-patterns — Caching, pub/sub messaging, rate limiting, and distributed locks

Getting Started

Install this bundle when starting a Python backend project. The recommended sequence:

1. Structure: Use python-packaging-patterns to set up pyproject.toml and project layout
2. API: Use fastapi-patterns for async API endpoints with Pydantic validation
3. Database: Use database-migration-patterns for schema management with Alembic
4. Caching: Use redis-patterns for caching and rate limiting layers
5. CLI: Use cli-tool-design for management commands and operational tooling

This pack covers the core Python backend stack used across ORGAN-III (commerce), ORGAN-IV (orchestration), and META-ORGANVM.
