# Dependências com yield

O FastAPI possui suporte para dependências que realizam <abbr title='também chamados de "código de saída", "código de cleanup", "código de teardown", "código de finalização", "código de saída para gerenciador de contextos", etc.'>alguns passos extras ao finalizar</abbr>.

Para fazer isso, utilize `yield` em vez de `return`, e escreva os passos extras (código) depois.

/// tip | Dica

Garanta que `yield` é utilizado apenas uma vez.

### Things to know

- Fields such as `version` and `pools` are mandatory, however all other fields are optional.
- Each pool expects a minimum of 2 nodes per pool, and unique non-repeating hosts for each argument.
