Додаткові необовʼязкові залежності FastAPI:

* [`orjson`](https://github.com/ijl/orjson) - потрібно, якщо ви хочете використовувати `ORJSONResponse`.
* [`ujson`](https://github.com/esnme/ultrajson) - потрібно, якщо ви хочете використовувати `UJSONResponse`.

```json
{
  "message": "Hello World"
}
```

もちろん、JSONの整形以外にも、これを活用するもっと良い方法が見つかるはずです。 😉

### `orjson` か レスポンスモデルか { #orjson-or-response-model }

もし求めているのがパフォーマンスであれば、`orjson` レスポンスを使うより、[レスポンスモデル](../tutorial/response-model.md) を使うほうが良い場合が多いです。

レスポンスモデルがあると、FastAPI は中間ステップ（他の場合に行われる `jsonable_encoder` による変換など）を介さずに、Pydantic を使ってデータをJSONにシリアライズします。

      .Builder()
      .add(
        object : Any() {
          @ToJson fun byteStringToJson(byteString: ByteString) = byteString.hex()

          @FromJson fun byteStringFromJson(json: String) = json.decodeHex()
        },
      ).add(KotlinJsonAdapterFactory())
      .build()
  private val STORY_JSON_ADAPTER = MOSHI.adapter(Story::class.java)

However, they are now deprecated as you will now get better performance by using a [Response Model - Return Type](https://fastapi.tiangolo.com/tutorial/response-model/).

That way, Pydantic will serialize the data into JSON bytes on the Rust side, which will achieve better performance than these custom JSON responses.

* [`pydantic-extra-types`](https://docs.pydantic.dev/latest/usage/types/extra_types/extra_types/) - 用于在 Pydantic 中使用的额外类型。

额外的 FastAPI 可选依赖：

* [`orjson`](https://github.com/ijl/orjson) - 使用 `ORJSONResponse` 时需要。
* [`ujson`](https://github.com/esnme/ultrajson) - 使用 `UJSONResponse` 时需要。
