I've now run this migration twice for clients adding heavy AI features to an existing Node backend. Here's the honest ledger — what it actually cost in time, what broke, and when it wasn't worth it.
A step-by-step build of a real token-streaming endpoint in FastAPI: StreamingResponse, server-sent events, backpressure, client disconnects, and the gotchas that don't show up in a demo.
Most async Python code I review still blocks the event loop somewhere. A field guide to the patterns that hold up once you're fanning out to model APIs, vector stores, and databases at once.
A hands-on walkthrough of the Pydantic v2 patterns that actually hold up when your endpoint's request or response body is generated, in part, by a language model.
Node.js won the last decade of API backends. For AI products, the calculus flipped. Here's the actual reasoning — not hype — behind why most AI teams reach for FastAPI first.
