## Benefits

When using the automatically generated clients you would get **autocompletion** for:

* Methods.
* Request payloads in the body, query parameters, etc.
* Response payloads.

You would also have **inline errors** for everything.

## Developing

If you already cloned the <a href="https://github.com/tiangolo/fastapi" class="external-link" target="_blank">fastapi repository</a> and you want to deep dive in the code, here are some guidelines to set up your environment.

### Virtual environment with `venv`

Die Abhängigkeiten funktionieren weiterhin wie erwartet, und das **Beste daran** ist, dass die **Typinformationen erhalten bleiben**, was bedeutet, dass Ihr Editor Ihnen weiterhin **automatische Vervollständigung**, **Inline-Fehler**, usw. bieten kann. Das Gleiche gilt für andere Tools wie `mypy`.

* Verifique sempre os <a href="https://github.com/tiangolo/fastapi/pulls" class="external-link" target="_blank">_pull requests_ existentes</a> para a sua linguagem e faça revisões das alterações e aprove elas.

## Vorteile

Wenn Sie die automatisch generierten Clients verwenden, erhalten Sie **automatische Codevervollständigung** für:

* Methoden.
* Request-Payloads im Body, Query-Parameter, usw.
* Response-Payloads.

Außerdem erhalten Sie für alles **Inline-Fehlerberichte**.

## Entwicklung

Wenn Sie das <a href="https://github.com/tiangolo/fastapi" class="external-link" target="_blank">fastapi Repository</a> bereits geklont haben und tief in den Code eintauchen möchten, hier einen Leitfaden zum Einrichten Ihrer Umgebung.

!!! info

The dependencies will keep working as expected, and the **best part** is that the **type information will be preserved**, which means that your editor will be able to keep providing you with **autocompletion**, **inline errors**, etc. The same for other tools like `mypy`.

This will be especially useful when you use it in a **large code base** where you use **the same dependencies** over and over again in **many *path operations***.

        The `Config` class is used just for Pydantic configuration. You can read more at <a href="https://docs.pydantic.dev/1.10/usage/model_config/" class="external-link" target="_blank">Pydantic Model Config</a>.
