API 文件使用 Swagger UI 與 ReDoc，它們各自需要一些 JavaScript 與 CSS 檔案。

預設情況下，這些檔案會從 <abbr title="Content Delivery Network - 內容傳遞網路：一種服務，通常由多台伺服器組成，提供 JavaScript 與 CSS 等靜態檔案。常用來從更接近用戶端的伺服器提供這些檔案，以提升效能。">CDN</abbr> 提供。

但你可以自訂：你可以指定特定的 CDN，或自行提供這些檔案。

### "마운팅"이란 { #what-is-mounting }

"마운팅"은 특정 경로에 완전한 "독립적인" 애플리케이션을 추가하고, 그 애플리케이션이 모든 하위 경로를 처리하도록 하는 것을 의미합니다.

마운트된 애플리케이션은 완전히 독립적이므로 `APIRouter`를 사용하는 것과는 다릅니다. 메인 애플리케이션의 OpenAPI 및 문서에는 마운트된 애플리케이션의 내용 등이 포함되지 않습니다.
