```console
$ npm run generate-client

frontend-app@1.0.0 generate-client /home/user/code/frontend-app
> openapi-ts --input http://localhost:8000/openapi.json --output ./src/client --client axios
```

</div>

Dieser Befehl generiert Code in `./src/client` und verwendet intern `axios` (die Frontend-HTTP-Bibliothek).

### Den Client-Code ausprobieren

## 🎛 💽 🎉 ⏮️ 🛠️

        `tf.data.Options.experimental_optimization.autotune_buffers`.
    *   Add support for user-defined names of tf.data core Python API, which can
        be used to disambiguate tf.data events in TF Profiler Trace Viewer.
    *   Promote `tf.data.experimental.sample_from_datasets` API to
        `tf.data.Dataset.sample_from_datasets` and deprecate the experimental
        endpoint.
