console.Log() shows nothing?

[strawberry 3.141]

@mortenbirkelund the module doesnt log in the terminal only the node_helper does. The module logs into electron or your browser start the mirror wih npm start dev

@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?

[mortenbirkelund]

Found the error. I needed to add

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

as css and now it is working.

[Snille]

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.

@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!
