當我們有含模型的 FastAPI 應用後，就能用 Hey API 來產生 TypeScript 用戶端。最快的方法是透過 npx：

```sh
npx @hey-api/openapi-ts -i http://localhost:8000/openapi.json -o src/client
```

這會在 `./src/client` 產生一個 TypeScript SDK。

你可以在他們的網站了解如何[安裝 `@hey-api/openapi-ts`](https://heyapi.dev/openapi-ts/get-started)，以及閱讀[產生的輸出內容](https://heyapi.dev/openapi-ts/output)。

### 使用 SDK { #using-the-sdk }

現在你可以匯入並使用用戶端程式碼。大致看起來會像這樣，你會發現方法有自動完成：

					TotalSize:   uint64(task.objInfo.Size),
					NumVersions: 1,
				}
				if task.objInfo.IsLatest {

				}
				t.addLastDayStats(task.event.StorageClass, ts)
			}
			t.activeTasks.Add(-1)
		}
	}
}

	t.lastDayMu.Lock()

    sort(castBuffer, 0, bufferSize, comparator);
    if (bufferSize > k) {
      Arrays.fill(buffer, k, buffer.length, null);
      bufferSize = k;
      threshold = buffer[k - 1];
    }
    // Up to bufferSize, all elements of buffer are real Ts (not null unless T includes null)

				return

			if err != nil {
