These types that have internal types are called "**generic**" types. And it's possible to declare them, even with their internal types.

To declare those types and the internal types, you can use the standard Python module `typing`. It exists specifically to support these type hints.

Em seguida, você pode retornar qualquer objeto que precise, como normalmente faria (um `dict`, um modelo de banco de dados, etc).

E se você declarou um `response_model`, ele ainda será usado para filtrar e converter o objeto que você retornou.

* Integração com modelo NER **spaCy**.

You can see those schemas because they were declared with the models in the app.

That information is available in the app's **OpenAPI schema**, and then shown in the API docs (by Swagger UI).

And that same information from the models that is included in OpenAPI is what can be used to **generate the client code**.

### Generate a TypeScript Client

Now that we have the app with the models, we can generate the client code for the frontend.
