Hi

Out of interest are global variable values retained when you hit the deploy button in nodered for a full deployment?

Are the values only forgotten if the instance of nodered is restarted (e.g computer reboot?)

Can you define what you mean by a global variable? Do you mean global context?

Yes when you initiate a variable with global.set(“varname”, value)

Does that define what happens when you do a Full Deploy using the default context store?

@Sirhc I suggest you try it and report the answer back here.
