    ```Javascript
    {!> ../../../docs_src/generate_clients/tutorial004.js!}
    ```

With that, the operation IDs would be renamed from things like `items-get_items` to just `get_items`, that way the client generator can generate simpler method names.

### Generate a TypeScript Client with the Preprocessed OpenAPI

    ```

=== "Node.js"

    ```Javascript
    {!> ../../../docs_src/generate_clients/tutorial004.js!}
    ```

Damit würden die Operation-IDs von Dingen wie `items-get_items` in `get_items` umbenannt, sodass der Client-Generator einfachere Methodennamen generieren kann.
