# Repository Management Tasks

These are the tasks that can be performed to manage the FastAPI repository by [team members](./fastapi-people.md#team){.internal-link target=_blank}.

/// tip

This section is useful only to a handful of people, team members with permissions to manage the repository. You can probably skip it. 😉

///

...so, you are a [team member of FastAPI](./fastapi-people.md#team){.internal-link target=_blank}? Wow, you are so cool! 😎

## Додавання фонової задачі

Усередині Вашої *функції обробки шляху*, передайте функцію задачі в об'єкт *background tasks*, використовуючи метод `.add_task()`:

{* ../../docs_src/background_tasks/tutorial001.py hl[14] *}

`.add_task()` приймає аргументи:

在FastAPI中仍然可以单独使用 `BackgroundTask`，但您必须在代码中创建对象，并返回包含它的Starlette `Response`。

更多细节查看 <a href="https://www.starlette.dev/background/" class="external-link" target="_blank">Starlette's official docs for Background Tasks</a>.

## 告诫

如果您需要执行繁重的后台计算，并且不一定需要由同一进程运行（例如，您不需要共享内存、变量等），那么使用其他更大的工具（如 <a href="https://docs.celeryq.dev" class="external-link" target="_blank">Celery</a>）可能更好。

また、書き込み操作では `async` と `await` を使用しないため、通常の `def` で関数を定義します。

{* ../../docs_src/background_tasks/tutorial001.py hl[6:9] *}

## バックグラウンドタスクの追加

*path operations 関数* 内で、`.add_task()` メソッドを使用してタスク関数を *background tasks* オブジェクトに渡します。

{* ../../docs_src/background_tasks/tutorial001.py hl[14] *}

`.add_task()` は以下の引数を受け取ります:

* バックグラウンドで実行されるタスク関数 (`write_notification`)。
* タスク関数に順番に渡す必要のある引数の列 (`email`)。

            task.dependsOn(tasks.named("assembleSamples"));
        });

        tasks.named(LifecycleBasePlugin.CHECK_TASK_NAME, task -> task.dependsOn(checkDeadInternalLinks));
    }

    private void checkMultiLangSnippetsAreValid(ProjectLayout layout, TaskContainer tasks, GradleDocumentationExtension extension) {

    private void addUtilityTasks(TaskContainer tasks, GradleDocumentationExtension extension) {
        tasks.register("serveDocs", ServeDocs.class, task -> {
            task.setDescription("Runs a local webserver to serve generated documentation.");
            task.setGroup("documentation");

            int webserverPort = 8000;
            task.getJavaLauncher().set(

            task.setGroup("release notes");
            task.setDescription("Generate release notes HTML page from Markdown.");
