# Full Stack FastAPI 템플릿 { #full-stack-fastapi-template }

템플릿은 일반적으로 특정 설정과 함께 제공되지만, 유연하고 커스터마이징이 가능하게 디자인 되었습니다. 이 특성들은 여러분이 프로젝트의 요구사항에 맞춰 수정, 적용을 할 수 있게 해주고, 템플릿이 완벽한 시작점이 되게 해줍니다. 🏁

많은 초기 설정, 보안, 데이터베이스 및 일부 API 엔드포인트가 이미 준비되어 있으므로, 여러분은 이 템플릿을 시작하는 데 사용할 수 있습니다.

This release also stabilizes many APIs in the `mockwebserver3` artifact that's new in 5.0.

 *  Breaking: `RecordedRequest.body` is now nullable. Null is used when the request does not have a
    body.

 *  Breaking: `RecordedRequest.chunkSizes` is now nullable. Null is used when the request does not
    use chunked encoding. This is different from an empty list - that indicates the request is
    chunked but has no data.
