**FastAPI** provides the same `WebSocket` directly just as a convenience for you, the developer. But it comes directly from Starlette.

///

## Await for messages and send messages

In your WebSocket route you can `await` for messages and send messages.

```Python hl_lines="48-52"
{!../../docs_src/websockets/tutorial001.py!}
```

You can receive and send binary, text, and JSON data.

## Try it

    public HtmlResponse reindexOnly(final ActionForm form) {
        validate(form, messages -> {}, this::asIndexHtml);
        verifyToken(this::asIndexHtml);
        if (startReindex(isCheckboxEnabled(form.replaceAliases), isCheckboxEnabled(form.resetDictionaries), form.numberOfShardsForDoc,
                form.autoExpandReplicasForDoc)) {
            saveInfo(messages -> messages.addSuccessStartedDataUpdate(GLOBAL));
        }

        }
        if (doc == null) {
            saveError(messages -> messages.addErrorsDocidNotFound(GLOBAL, form.docId));
            return redirect(ErrorAction.class);
        }

        final String content = viewHelper.createCacheContent(doc, form.hq);
        if (content == null) {
            saveError(messages -> messages.addErrorsDocidNotFound(GLOBAL, form.docId));
            return redirect(ErrorAction.class);

delivery_mode  (number)    set to '1' for non-persistent or '2' for persistent queue
queue_dir      (path)      staging dir for undelivered messages e.g. '/home/events'
queue_limit    (number)    maximum limit for undelivered messages, defaults to '100000'
comment        (sentence)  optionally add a comment to this setting
```
