Module ignoring node_helper.js?

[mjtice]

I’m sure I’m missing something really obvious here… but I can’t see what it is. The contents of MMM-HiWorld print out just fine but the console logging in node_helper.js never happens. As I understand it (from reading some other forum posts) I need to initialize node_helper.js via a call in start: function()?

MMM-HiWorld.js:

$ cat MMM-HiWorld.js
Module.register("MMM-HiWorld",{
    // Default module config.
	// Default module config.
	defaults: {
		text: "Hi World!",
		animationSpeed: 1000,
	},

start: function() {
    this.sendSocketNotification('Starting');
    var self = this;
    setInterval(function() {
        self.updateDom(); // no speed defined, so it updates instantly.
    }, 1000); //perform every 1000 milliseconds.
},

	// Override dom generator.
getDom: function() {
    var wrapper = document.createElement("div");
    wrapper.innerHTML = this.config.text;
    return wrapper;
},

});

node_helper.js:

$ cat node_helper.js
var NodeHelper = require('node_helper');

module.exports = NodeHelper.create({
    start: function() {
        console.log('Starting node_helper');
    },

    socketNotificationReceived: function(notification, payload) {
      console.log('Okay, I got a notification.');
    },
});

This is Raspbian Jessie (Raspberry Pi 2) and node v6.9.2.

Thanks!

node_helper.js doesn’t output console.log() to the same place the MMM-HiWorld.js does. You’ll see the log pop up in the npm output. You can see the data when you run npm start on the raspberry pi. If you are using pm2 to autostart Magic Mirror, you can ssh into your pi and run
tail -f ~/.pm2/logs/mm-out-0.log to see the console messages. You can also run tail -f ~/.pm2/logs/mm-error-0.log to see all of your node_helper.js errors.

Wow, thanks @mochman! Now that you mention it that makes perfect sense because node_helper.js isn’t executed on the client-end (right?).
