# How To - Recipes

Here you will see different recipes or "how to" guides for **several topics**.

Most of these ideas would be more or less **independent**, and in most cases you should only need to study them if they apply directly to **your project**.

If something seems interesting and useful to your project, go ahead and check it, but otherwise, you might probably just skip them.

## Other middlewares

There are many other ASGI middlewares.

For example:

* <a href="https://docs.sentry.io/platforms/python/guides/fastapi/" class="external-link" target="_blank">Sentry</a>
* <a href="https://github.com/encode/uvicorn/blob/master/uvicorn/middleware/proxy_headers.py" class="external-link" target="_blank">Uvicorn's `ProxyHeadersMiddleware`</a>

* <a href="https://docs.porter.run/language-specific-guides/fastapi" class="external-link" target="_blank">Porter</a>

    Sie können diesen Teil wahrscheinlich überspringen.

Es gibt eine alternative Möglichkeit, diese Logik zu definieren, sodass sie beim *Hochfahren* und beim *Herunterfahren* ausgeführt wird.

You might want to try their services and follow their guides:
