## Streaming de SSE con FastAPI { #stream-sse-with-fastapi }

Para hacer streaming de SSE con FastAPI, usa `yield` en tu path operation function y establece `response_class=EventSourceResponse`.

import `EventSourceResponse` de `fastapi.sse`:

{* ../../docs_src/server_sent_events/tutorial001_py310.py ln[1:25] hl[4,22] *}

Cada ítem producido con `yield` se codifica como JSON y se envía en el campo `data:` de un evento SSE.
