It is because there is an error (at least I think so - I am new too) and no instructions on where to put the function.

1. change the Module.register(“MMM-Timetable”) to Module.register(“MMM-Test”)

2. The article does not tell you where to put the getDom function when it is first introduced. Replace the getDom: function() {}. with the code shown. In other words, don’t just add it to the file. This article would have benefited from a final section that gave the entire code.

I think the original author at least expected us to be very familiar with Node.js (fair enough), but alas, I am not so it took a bit of work to figure it out. :-)

Here it is, for the first part:

Module.register(“MMM-Test”, {
defaults: {},
start: function () {},

getDom: function() {
var element = document.createElement(“div”)
element.className = “myContent”
element.innerHTML = “Hello, World!”
return element
},
notificationReceived: function() {},
socketNotificationReceived: function() {},
})
