Щоб транслювати SSE з FastAPI, використовуйте `yield` у вашій *функції операції шляху* і встановіть `response_class=EventSourceResponse`.

Імпортуйте `EventSourceResponse` з `fastapi.sse`:

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

Кожен елемент, повернений через `yield`, кодується як JSON і надсилається в полі `data:` події SSE.

		} else {
