### Client-Methodennamen

Im Moment sehen die generierten Methodennamen wie `createItemItemsPost` nicht sehr sauber aus:

```TypeScript
ItemsService.createItemItemsPost({name: "Plumbus", price: 5})
```

... das liegt daran, dass der Client-Generator für jede *Pfadoperation* die OpenAPI-interne **Operation-ID** verwendet.

👉 💼 👆 ✔️:

* `ItemsService`
* `UsersService`
