## Клиент WebSockets { #websockets-client }

### В продакшн { #in-production }

В продакшн у вас, вероятно, есть фронтенд, созданный с помощью современного фреймворка вроде React, Vue.js или Angular.

И для взаимодействия с бекендом по WebSocket вы, скорее всего, будете использовать инструменты вашего фронтенда.

Indem Sie nur `BackgroundTasks` (und nicht `BackgroundTask`) verwenden, ist es dann möglich, es als *Pfadoperation-Funktion*-Parameter zu verwenden und **FastAPI** den Rest für Sie erledigen zu lassen, genau wie bei der direkten Verwendung des `Request`-Objekts.

## Reprendre avec `Last-Event-ID` { #resuming-with-last-event-id }

Quand un navigateur se reconnecte après une coupure, il envoie le dernier `id` reçu dans l’en-tête `Last-Event-ID`.

Vous pouvez le lire comme paramètre d’en-tête et l’utiliser pour reprendre le flux là où le client s’était arrêté :

Adding an `\f` (an escaped "form feed" character) causes **FastAPI** to truncate the output used for OpenAPI at this point.

It won't show up in the documentation, but other tools (such as Sphinx) will be able to use the rest.
