In node-red how can I send a message to the debug tab with out using debug node? Is there method I could call

Question

I dont want use debug node. rather I want to just pass the debug message to the debug tab directly from my customized node. So I was wondering if may be there is a method that I could use to achieve this.

Why do you not want to use a debug node? – hardillb Mar 03 '16 at 09:21 — hardillb, Mar 03 '16 at 09:21

The node object is exposed in the context of a function node and had 2 functions that will add something to the debug tab

node.warn() and node.error() both print to the debug tab (and also to the console) but with suitable colours and header messages e.g.

node.warn(msg.payload);
return msg;

Be aware that node.error will also raise a message that can be caught by the Catch node so if you just want to report status from with in a function then the node.warn is probably best

Once a `node.error()` is invoked, should it be followed with a `return null` statement to halt the flow? Or, will that happen on its own? – cogitoergosum Jul 03 '18 at 02:25
That entirely depends on the context of where it was called – hardillb Jul 03 '18 at 06:09
An example, please? – cogitoergosum Jul 03 '18 at 08:10
It's bad that there is no node.debug – Xdg Nov 18 '21 at 10:28

@Xdg There is a `node.debug()` but it is not for sending items to the sidebar. https://nodered.org/docs/user-guide/writing-functions#logging-events – hardillb Nov 18 '21 at 11:33
