## `fastapi dev`

`fastapi dev` 명령을 실행하면 개발 모드가 시작됩니다.

기본적으로 **자동 재시작(auto-reload)** 기능이 활성화되어, 코드에 변경이 생기면 서버를 자동으로 다시 시작합니다. 하지만 이 기능은 리소스를 많이 사용하며, 비활성화했을 때보다 안정성이 떨어질 수 있습니다. 따라서 개발 환경에서만 사용하는 것이 좋습니다. 또한, 서버는 컴퓨터가 자체적으로 통신할 수 있는 IP 주소(`localhost`)인 `127.0.0.1`에서 연결을 대기합니다.

## `fastapi run`

`fastapi run` 명령을 실행하면 기본적으로 프로덕션 모드로 FastAPI가 시작됩니다.
