<script type="text/html" data-help-name="websocket in">
|
|
<p>WebSocket input node.</p>
|
|
<p>By default, the data received from the WebSocket will be in <code>msg.payload</code>.
|
|
The socket can be configured to expect a properly formed JSON string, in which
|
|
case it will parse the JSON and send on the resulting object as the entire message.</p>

<script type="text/html" data-help-name="websocket out">
|
|
<p>WebSocket out node.</p>
|
|
<p>By default, <code>msg.payload</code> will be sent over the WebSocket. The socket
|
|
can be configured to encode the entire <code>msg</code> object as a JSON string and send that
|
|
over the WebSocket.</p>
|
|
|
|
<p>If the message arriving at this node started at a WebSocket In node, the message
|
|
will be sent back to the client that triggered the flow. Otherwise, the message
|
|
will be broadcast to all connected clients.</p>
|
|
<p>If you want to broadcast a message that started at a WebSocket In node, you
|
|
should delete the <code>msg._session</code> property within the flow.</p>
