Dear Sir
May i ask how to listen deploy button. how to hold on and move on deploy the flow. as before deploy i need to verify if this flow is created or edited by insider.
Best regard!
Henry

While Node-RED does issue an event when deploy happens - I think there may be a pre-deploy event as well, can't quite remember but if there is, that would let you prevent a deploy from occurring - it isn't really what Node-RED is set up for I don't believe. Anyone with rights to change the flows via the Editor interface is assumed to be trusted to change the flow. There isn't even an audit that would record a specific Node-RED user (as opposed to the OS user that runs Node-RED) has made a change, something that would be a bare minimum for a secure system where multiple users are allowed to make changes.
I think that you would probably need to embed Node-RED in your own service (which is easy enough) in order to achieve anything more.
