### Run it

Run the server with:

<div class="termy">

```console
$ uvicorn main:app --reload

INFO:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
INFO:     Started reloader process [28720]
INFO:     Started server process [28722]
INFO:     Waiting for application startup.
INFO:     Application startup complete.
```

This is in contrast to the **development** stages, where you are constantly changing the code, breaking it and fixing it, stopping and restarting the development server, etc.

## Deployment Strategies

</div>

... das beinhaltet auch `uvicorn`, welchen Sie als Server verwenden können, der ihren Code ausführt.

!!! note "Hinweis"
    Sie können die einzelnen Teile auch separat installieren.

    Das folgende würden Sie wahrscheinlich tun, wenn Sie Ihre Anwendung in der Produktion einsetzen:

    ```
    pip install fastapi
    ```

    Installieren Sie auch `uvicorn` als Server:

    ```
    pip install "uvicorn[standard]"

```

</div>

...that also includes `uvicorn`, that you can use as the server that runs your code.

!!! note
    You can also install it part by part.

    This is what you would probably do once you want to deploy your application to production:

    ```
    pip install fastapi
    ```

    Also install `uvicorn` to work as the server:

    ```
    pip install "uvicorn[standard]"
    ```

<div class="termy">

```console
$ pip install fastapi

---> 100%
```
