We are using an invented header to simplify this example.

## Another module with `APIRouter` { #another-module-with-apirouter }

Let's say you also have the endpoints dedicated to handling "items" from your application in the module at `app/routers/items.py`.

Основной веб-сервер для запуска приложений **FastAPI**.

Также вы можете использовать опцию командной строки `--workers`, чтобы получить асинхронный многопроцессный сервер.
