# Dependencies with yield { #dependencies-with-yield }

FastAPI supports dependencies that do some <dfn title='sometimes also called "exit code", "cleanup code", "teardown code", "closing code", "context manager exit code", etc.'>extra steps after finishing</dfn>.

To do this, use `yield` instead of `return`, and write the extra steps (code) after.

/// tip

Make sure to use `yield` one single time per dependency.

# `yield`를 사용하는 의존성 { #dependencies-with-yield }

FastAPI는 <dfn title='때로는 "exit code", "cleanup code", "teardown code", "closing code", "context manager exit code" 등으로도 불립니다'>작업 완료 후 추가 단계</dfn>를 수행하는 의존성을 지원합니다.

이를 구현하려면 `return` 대신 `yield`를 사용하고, 추가로 실행할 단계 (코드)를 그 뒤에 작성하세요.

/// tip

각 의존성마다 `yield`는 한 번만 사용해야 합니다.
