We have embedded the Node-Red into existing Node JS with an express framework app & we wanted to make a sync call to the flow programmatically (without HTTP call) from the same app. Is this something possible?
If Not, then what is the right approach to make a sync call to Node-Red flow?
EDIT
You could use the above approach to pass to the host application a method provided by a function node (to be called by your Host app), but it could get messy really quickly.
