from unicorn import UnicornMiddleware

app = FastAPI()

app.add_middleware(UnicornMiddleware, some_config="rainbow")
```

`app.add_middleware()` receives a middleware class as the first argument and any additional arguments to be passed to the middleware.

## Integrated middlewares

**FastAPI** includes several middlewares for common use cases, we'll see next how to use them.

/// note | "Technical Details"

from unicorn import UnicornMiddleware

app = FastAPI()

app.add_middleware(UnicornMiddleware, some_config="rainbow")
```

`app.add_middleware()` empfängt eine Middleware-Klasse als erstes Argument und dann alle weiteren Argumente, die an die Middleware übergeben werden sollen.

## Integrierte Middleware

**FastAPI** enthält mehrere Middlewares für gängige Anwendungsfälle. Wir werden als Nächstes sehen, wie man sie verwendet.
