Running `fastapi dev` initiates development mode.

By default, **auto-reload** is enabled, automatically reloading the server when you make changes to your code. This is resource-intensive and could be less stable than when it's disabled. You should only use it for development. It also listens on the IP address `127.0.0.1`, which is the IP for your machine to communicate with itself alone (`localhost`).

 * <p>Examples of use:

FastAPI를 사용하지 않더라도, 높은 호환성 및 <a href="https://anyio.readthedocs.io/en/stable/" class="external-link" target="_blank">AnyIO</a>의 이점(예: *구조화된 동시성*)을 취하기 위해 <a href="https://anyio.readthedocs.io/en/stable/" class="external-link" target="_blank">AnyIO</a>를 사용해 비동기 응용프로그램을 작성할 수 있습니다.

파이썬에서 `async`와 `await`를 사용하게 된 것은 비교적 최근의 일입니다.
