# JSON Lines 스트리밍 { #stream-json-lines }

연속된 데이터를 "**스트림**"으로 보내고 싶다면 **JSON Lines**를 사용할 수 있습니다.

/// info

FastAPI 0.134.0에 추가되었습니다.

///

## 스트림이란 { #what-is-a-stream }

데이터를 "**스트리밍**"한다는 것은 애플리케이션이 전체 항목 시퀀스가 모두 준비될 때까지 기다리지 않고 클라이언트로 데이터 항목을 보내기 시작한다는 뜻입니다.

즉, 첫 번째 항목을 보내면 클라이언트는 그것을 받아 처리하기 시작하고, 그동안 애플리케이션은 다음 항목을 계속 생성할 수 있습니다.
