Can I implement real-time streaming with this skill?

Yes, it includes standardized implementations for both WebSockets (bidirectional) and Server-Sent Events (one-way streaming) for real-time updates.

Does this skill support SQLAlchemy and other ORMs?

Yes, it provides patterns for SQLAlchemy's async engine, Tortoise ORM, and Motor for MongoDB, ensuring efficient database connectivity.

How do background tasks work in these patterns?

It utilizes FastAPI's BackgroundTasks class to handle fire-and-forget logic, allowing the server to return a response immediately while processing tasks in the background.

When should I use async instead of sync in FastAPI?

Use async for I/O-bound operations like database queries or external API calls. Use sync (standard def) for CPU-bound operations to prevent blocking the event loop.

API Development

Implements high-performance asynchronous patterns for FastAPI applications to optimize concurrency and resource usage.

This skill provides expert guidance and implementation patterns for leveraging FastAPI's asynchronous capabilities to build scalable, non-blocking APIs. It covers a wide range of essential patterns including async vs. sync route selection, asynchronous database integration with SQLAlchemy and Motor, real-time communication via WebSockets and Server-Sent Events (SSE), and efficient background task management. By following these patterns, developers can ensure their Claude-generated code avoids common pitfalls like blocking the event loop, resulting in production-grade services capable of handling high-concurrency workloads.
