That would work for most of the cases. 😎

You could use that command for example to start your **FastAPI** app in a container, in a server, etc.

## ASGI Servers { #asgi-servers }

Let's go a little deeper into the details.

FastAPI uses a standard for building Python web frameworks and servers called <abbr title="Asynchronous Server Gateway Interface">ASGI</abbr>. FastAPI is an ASGI web framework.

* Бэкенд построен на фреймворке <a href="https://github.com/fastapi/fastapi" class="external-link" target="_blank">**FastAPI**</a>:
    * **Быстрый**: Высокопроизводительный, на уровне **NodeJS** и **Go** (благодаря Starlette и Pydantic).
    * **Интуитивно понятный**: Отличная поддержка редактора. <dfn title="также известное как автозаполнение, интеллектуальность, автозавершение">Автодополнение кода</dfn> везде. Меньше времени на отладку.

        crawlingInfoPager.clear();
        return asHtml(path_AdminCrawlinginfo_AdminCrawlinginfoJsp).renderWith(data -> {
            searchPaging(data, form);
        });
    }

    /**
     * Go back to the list page.
     * @param form The search form.
     * @return The HTML response.
     */
    @Execute
    @Secured({ ROLE, ROLE + VIEW })
    public HtmlResponse back(final SearchForm form) {

        } catch (final UnsupportedEncodingException uee) {}
        dstIndex += scope.length();

        dst[dstIndex++] = (byte) 0x00;

        // now go over scope backwards converting '.' to label length

        int i = dstIndex - 2;
        final int e = i - scope.length();
        int c = 0;

        do {
            if (dst[i] == '.') {

Et c'est le même niveau de performance que celui obtenu avec **FastAPI**.

* Des performances vraiment impressionnantes. C'est l'<a href="https://github.com/encode/starlette#performance" class="external-link" target="_blank">un des framework Python les plus rapide, à égalité avec **NodeJS** et **GO**</a>.
* Le support des **WebSockets**.
* Le support de **GraphQL**.
* Les <abbr title="En anglais: In-process background tasks">tâches d'arrière-plan.</abbr>
* Des évènements de démarrages et d'arrêt.

Notice that the *path operations* define the models they use for request payload and response payload, using the models `Item` and `ResponseMessage`.

### API Docs { #api-docs }

If you go to `/docs`, you will see that it has the **schemas** for the data to be sent in requests and received in responses:

So we have a dedicated thread for every socket that just reads frames and dispatches them.

# Use "xargs" to parse quoted args.
