This extension enables you to create WebSocket endpoints to that act as either a WebSocket server, or as a client to connect an existing WebSocket .

It is built on top of the Eclipse Vert.x HTTP server provided by the `quarkus-vertx-http` extension.

</dependency>

Check the xref:user-guide/index.adoc[User guide] for more information about writing Camel Quarkus applications.

== Usage

=== Vert.x WebSocket consumers

When you create a Vert.x WebSocket consumer (E.g with `from("vertx-websocket")`), the host and port configuration in the URI are redundant since the WebSocket will always be hosted on 
the Quarkus HTTP server.

The configuration of the consumer can be simplified to only include the resource path of the WebSocket. For example.

[source,java]
----
from("vertx-websocket://my-websocket-path")
    .setBody().constant("Hello World");
----



== Additional Camel Quarkus configuration

=== Vert.x WebSocket server configuration

Configuration of the Vert.x WebSocket server is managed by Quarkus. Refer to the https://quarkus.io/guides/all-config#quarkus-vertx-http_quarkus-vertx-http-eclipse-vert.x-http[Quarkus HTTP configuration guide]
for the full list of configuration options.

To configure SSL for the Vert.x WebSocket server, follow the https://quarkus.io/guides/http-reference#ssl[secure connections with SSL guide].
Note that configuring the server for SSL with `SSLContextParameters` is not currently supported.

=== Character encodings

Check the xref:user-guide/native-mode.adoc#charsets[Character encodings section] of the Native mode guide if you expect
your application to send or receive requests using non-default encodings.
