<p>The Debug node can be connected to the output of any node. It will display the timestamp, <b>msg.topic</b> and <b>msg.payload</b> fields of any messages it receives in the debug tab of the sidebar.
|
|
<br/>The sidebar can be accessed under the options drop-down in the top right corner.</p>
|
|
<p>The button to the right of the node will toggle it's output on and off so you can de-clutter the debug window.</p>
|
|
<p>If the payload is an object it will be stringified first for display and indicate that by saying "(Object) ".</p>
|
|
<p>If the payload is a buffer it will be stringified first for display and indicate that by saying "(Buffer) ".</p>
|
|
<p>Selecting any particular message will highlight (in red) the debug node that reported it. This is useful if you wire up multiple debug nodes.</p>
|
|
<p>Optionally can show the complete msg object - but the screen can get messy.</p>
|
|
<p>In addition any calls to node.warn or node.error will appear here.</p>
