    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?

                @easty in the script that starts mm do

                export ELECTRON_ENABLE_LOGGING=1

                or do that before u manually type npm start

                or use the MMM-Logging module (not mine)

                  Getting error EADDRINUSE and MM is blank, though I was trying to debug a module that stopped working yesterday 1st October.

                  At this point, I will delete and reinstall MM and wait for the module developer to update or move to an alternative. I traced the error back to http data request made by node helper js but haven’t been able to find a way to see the console.log or log.info for it. The http link produces json data correctly.

                  Edit

                  Okay this error was to do with the module, I was curious so I deleted the folder for the module and its working again. I can see info logging in terminal.

                  How can I see info logging for node helper js?

                    @easty u are using pm2 to launch mm.

                    so open a terminal window and do

                    pm2 status
                    pm2 stop x

                    where x is the name (MagicMirror if you used my install script})
                    or the number in the row of output

                    u don’t have to reinstall

                    pm2 info x

                    will tell you how the process is started mm.sh
                    which is what u would modify

                    using pm2, u can also see the logs by using the command,
                    pm2 logs --lines=???
                    where ??? is a number, 15 by default

                      @sdetweil

                      I haven’t installed pm2, I’m updating files through the file manager and using visual code editor. I couldn’t see console logging of node helper through the browser based developer tools but could see it through MM output in its terminal window. So thank you for showing me how to enable logging, that made a big difference.

                      I’ve got the module working again - seems like since yesterday, its decided not to like using https but works find with unsecure http. Through a browser that http link works fine through http or https so was difficult to figure out. Not sure if something changed with the website or with MM http. Most likely the website.

                      Anyway, appreciate the help!
