추가로 Starlette의 모든 보안 기능(**세션 쿠키** 포함)도 제공합니다.

모두 재사용 가능한 도구와 컴포넌트로 만들어져 있어, 여러분의 시스템, 데이터 저장소, 관계형 및 NoSQL 데이터베이스 등과 쉽게 통합할 수 있습니다.

html/template will escape URLs in the `url=` portion of the content attribute of
HTML meta tags. The default `htmlmetacontentescape=1` will cause URLs to be
escaped. Setting `htmlmetacontentescape=0` disables this behavior. To avoid
content injection attacks, this setting and default was backported to Go 1.25.8
and Go 1.26.1.

Go 1.27 changes the default for `tracebacklabels` (added in [Go 1.26](#go-126))

- **Multi-Threading**: Configurable thread pools for high-performance crawling
- **Fault Tolerance**: Built-in retry mechanisms and error handling
- **Flexible Configuration**: XML-based dependency injection with LastaFlute DI
- **Extensible Architecture**: Plugin system for custom extractors, transformers, and clients
- **Rate Limiting**: Politeness policies and interval controllers

### 依存性の注入 { #dependency-injection }

FastAPI には、非常に使いやすく、かつ非常に強力な <dfn title='別名: コンポーネント、リソース、サービス、プロバイダー'><strong>依存性の注入</strong></dfn> システムがあります。

* 依存関係は依存関係を持つこともでき、階層または **依存関係の「グラフ」** を作成できます。
* すべてフレームワークによって**自動的に処理**されます。
