|
<p>A function block where you can write code to do more interesting things.</p>
|
|
<p>The message is passed in as a JavaScript object called <code>msg</code>.</p>
|
|
<p>By convention it will have a <code>msg.payload</code> property containing
|
|
the body of the message.</p>
|
|
<p>If your node need to log anything use the <code>node</code> object:
|
|
<ul>
|
|
<li>Info: <code>node.log(msg);</code></li>
|
|
<li>Warning: <code>node.warn(msg);</code></li>
|
|
<li>Error: <code>node.error(msg);</code></li>
|
|
</ul>
|
|
</p>
|
|
<p>The function should return the messages it wants to pass on to the next nodes
|
|
in the flow. It can return:</p>
|
|
<ul>
|
|
<li>a single message object - passed to nodes connected to the first output</li>
|
|
<li>an array of message objects - passed to nodes connected to the corresponding outputs</li>
|
|
</ul>
|
|
<p>If any element of the array is itself an array of messages, multiple
|
|
messages are sent to the corresponding output.</p>
|
|
<p>If null is returned, either by itself or as an element of the array, no
|
|
message is passed on.</p>
