# GraphQL { #graphql }

**FastAPI** は **ASGI** 標準に基づいているため、ASGI に対応した任意の **GraphQL** ライブラリを簡単に統合できます。

同じアプリケーション内で通常の FastAPI の *path operation* と GraphQL を組み合わせて使えます。

/// tip | 豆知識

**GraphQL** は非常に特定のユースケースを解決します。

一般的な **Web API** と比べると、**長所** と **短所** があります。

ご自身のユースケースで得られる **利点** が **欠点** を補うかどうかを評価してください。 🤓

## GraphQL ライブラリ { #graphql-libraries }

/// tip

We'll discuss the `@lru_cache` in a bit.

For now you can assume `get_settings()` is a normal function.

///

And then we can require it from the *path operation function* as a dependency and use it anywhere we need it.
