Но в реальных проектах, при внедрении системы безопасности, вы получите больше пользы используя интегрированные [средства защиты (следующая глава)](../security/index.md){.internal-link target=_blank}.

## Исключения в dependencies и возвращаемые значения

Вы можете использовать те же *функции* зависимостей, что и обычно.

### Требования к зависимостям

For example, let's add <a href="https://github.com/Rebilly/ReDoc/blob/master/docs/redoc-vendor-extensions.md#x-logo" class="external-link" target="_blank">ReDoc's OpenAPI extension to include a custom logo</a>.

### Normal **FastAPI**

First, write all your **FastAPI** application as normally:

{* ../../docs_src/extending_openapi/tutorial001.py hl[1,4,7:9] *}

                return
            }
            const li = document.createElement('li')
            li.innerHTML = `<a href="${v.html_url}" target="_blank">★ ${v.stargazers_count} - ${v.full_name}</a> by <a href="${v.owner.html_url}" target="_blank">@${v.owner.login}</a>`
            ul.append(li)
        })
    }

    setupTermynal();
    showRandomAnnouncement('announce-left', 5000)
