# Dependencias con yield

FastAPI admite dependencias que realizan algunos <abbr title='sometimes also called "exit code", "cleanup code", "teardown code", "closing code", "context manager exit code", etc.'>pasos adicionales después de finalizar</abbr>.

Para hacer esto, usa `yield` en lugar de `return` y escribe los pasos adicionales (código) después.

/// tip | Consejo

Asegúrate de usar `yield` una sola vez por dependencia.
