    @mortenbirkelund these console.log() statements are not crated in the node application, but in the browser. Open the mirror in a main stream browser (IE or chrome or something) and hit F12 which will bring up the dev tools look in the console there for your message.

      @strawberry-3.141
      Just to add, because I found this irritating at first:
      If your browser does not open the console in dev mode then press F12 (works in every common browser) and look at the error/warning/log output there

      Ah, @izanbard was faster :-)

        @strawberry-3.141 said in console.Log() shows nothing?:

        npm start dev

        Thank you very much, both of you. Now I can see the logs.

          @mortenbirkelund just a note if you put a console.log() in the node_helper, then it apears on the command line output (or PM2 out.log if you are using PM2)

            Thank you once again for your help. Now that I understand where to see the logs, i can see that my button is not working. Anybody who knows why nothing happens when I click the button

            Module.register("MMM-Slider",{
            
            	// Default module config.
            	defaults: {
            		//text: "Hello World!"
            
            	},
            
            	// Override dom generator.
            	getDom: function() {
            		var wrapper = document.createElement("div");
            		
            		wrapper.appendChild(this.createButton());
            		return wrapper;
            	},
            	
            	createButton: function() {
            		var button = document.createElement("span");
            		button.innerHTML ="Click me";
            		button.id = this.identifier + "_button";
            		
            		button.addEventListener("click", function () {
            			console.log("The button was clicked");
            		});
            
            		return button;
            	}
            	
            });

              @Snille I have looked at your button module for inspiration. Do you know why nothing happens when I click the button?

                Found the error. I needed to add

                .region.fullscreen {
                z-index: -1;
                }

                as css and now it is working.

                  Hmm… I don’t have any custom css om my develop-version of MM, but the problem is of course that you will not see the pointer when moving over to the “mirror” if you are using a mouse.
                  You can add a custom.css with only:

                  body {
                    cursor: pointer;
                   }
                  

                  then you will see where you “are” when moving the mouse. :)
                  But you should not need anything else.

                  If you cant find it, make it and share it!

                    @mortenbirkelund I know this is really 4 years old, but it was my first match on Google. I couldn’t figure out why logs weren’t printing to terminal.

                    Anyhow, to make Electron print to terminal, add this to the environment variables:

                    ELECTRON_ENABLE_LOGGING=1

                    Hope it helps others!

                      @hasbean For a complete beginner, how do you do add that statement to environment variables?
