python-backend-fastapi

What problem does it solve?

This Skill targets developers building modern Python backends with FastAPI and Pydantic v2, streamlining endpoint development, validation, and migrations to reduce boilerplate and errors.

Core Features & Use Cases

• Thin endpoint handlers with a service layer to keep business logic out of controllers.
• Pydantic v2 models & OpenAPI alignment for robust request/response validation and API contracts.
• Alembic migrations & tests to manage schema changes reliably with idempotent upgrades/downgrades.
• ETL/parsers and streaming data workflows with structured logging and error handling for ingestion pipelines.
• ** pytest-based tests** to verify endpoints, services, and migrations across environments.

Quick Start

Start a FastAPI project, implement a new endpoint with a thin handler, add a service layer, and create an idempotent Alembic migration.
