* Then it returns the **response**.

/// note | "Technical Details"

If you have dependencies with `yield`, the exit code will run *after* the middleware.

If there were any background tasks (documented later), they will run *after* all the middleware.

## Erstellung einer Middleware

* Ele pode fazer algo com essa **resposta** ou executar qualquer código necessário.
* Então ele retorna a **resposta**.

/// note | "Detalhes técnicos"

Se você tiver dependências com `yield`, o código de saída será executado *depois* do middleware.

Se houver alguma tarefa em segundo plano (documentada posteriormente), ela será executada *depois* de todo o middleware.

## Criar um middleware

* می تواند کاری با **پاسخ** انجام دهید یا هر کد مورد نیازتان را اجرا کند.
* سپس **پاسخ** را برمی گرداند.

/// توجه | "جزئیات فنی"

در صورت وجود وابستگی هایی با `yield`، کد خروجی **پس از** اجرای میان‌‌افزار اجرا خواهد شد.

در صورت وجود هر گونه وظایف پس زمینه (که در ادامه توضیح داده می‌شوند)، تمام میان‌افزارها *پس از آن* اجرا خواهند شد.
