publish

Publishes a message on the topic tree of the current page.

Example:

{% button text="Hello" action={publish topic="some/topic" js_msg="Hello World!"} %}

When clicked, the message set to the message "Hello World!" is published.

Another example, now publishing a more complex message:

{% button text="hello" action={publish topic="some/topic" foo="bar" spam="eggs"} %}

When clicked, the message set to the message {foo: "bar", spam: "eggs"} is published.

Prefix the topic with bridge/origin/ to relay it to the topic tree on the server.
