Any way to see an output in node-red?

I'm a beginner in node-red and I have to continue a project already started.

I want to do some "checkpoint testing" to see what's in some variables; are there any ways to print the values of variables (in the javascript nodes)? And where can we see the output then?

Thank you, Etienne

  • From the Node-RED docs. http://nodered.org/docs/writing-functions#logging-events

    You can use node.log(). node.warn() or node.error() to output information from with in a function node.
