## Create a TypeScript SDK { #create-a-typescript-sdk }

Let's start with a simple FastAPI application:

{* ../../docs_src/generate_clients/tutorial001_py39.py hl[7:9,12:13,16:17,21] *}

Notice that the *path operations* define the models they use for request payload and response payload, using the models `Item` and `ResponseMessage`.

    @Resource
    protected UrlFilterService urlFilterService;

    public static byte[] calculateMacArcfourHMACMD5(int keyusage, Key key, byte[] data) throws GeneralSecurityException {
        int ms_usage = mapArcfourMD5KeyUsage(keyusage);

この設定では、自動APIドキュメントは以下の様になります:

## タグのためのメタデータ

さらに、パラメータ `openapi_tags` を使うと、path operations をグループ分けするための複数のタグに関するメタデータを追加できます。

それぞれのタグ毎にひとつの辞書を含むリストをとります。

それぞれの辞書は以下をもつことができます:

* `name` (**必須**): *path operations* および `APIRouter` の `tags` パラメーターで使用するのと同じタグ名である `str`。
* `description`: タグの簡単な説明文である `str`。 Markdownで記述でき、ドキュメントUIに表示されます。
