As far as I know, Nodes send and receive messages between nodes in an event-driven manner.
For example, you can view the results for data generated, such as debug nodes.
Within the debug node, we checked that messages were sent and received using the public and the subscription.
So I'm currently developing a new component using Node-RED,
do you have any documents related to event-handler?
Or is there a place where I can see related information?
If you know the information, please share it with me.
