SOLVED node_helper.js does not work.

[emrhssla]

I transferred what I had done with Mac to the Raspberry pie. I only tried the basic reservation code because the result I wanted was not available. But it didn’t work, either.
It’s good at Mac. Why not at Raspberry Pi?
MMM-TestPython.js

var Testpythons;
Module.register("MMM-Testpython", {

    defaults: {},
    start: function (){
        Testpythons = this;
    },
  
  getDom: function() {
    var element = document.createElement("div")
    element.className = "myContent"
    element.id="divid"
    element.innerHTML = "Hello, World!!! " + this.config.foo
    var subElement = document.createElement("p")
    subElement.innerHTML = "Click" 
    subElement.id = "clickid"
    element.appendChild(subElement)
    return element
  },
  
  notificationReceived: function(notification, payload, sender) {
    switch(notification) {
      case "DOM_OBJECTS_CREATED":
      var elem = document.getElementById("clickid")
      elem.addEventListener("click", () => {
        Testpythons.sendSocketNotification("TEST")
        console.log("hello~hello~hello~hello~hello~hello~hello~hello~hello~hello~")
        elem.innerHTML = "click success"       
      }) 
        break
    }
  },
  socketNotificationReceived: function(notification, payload) {
    switch(notification) {
      case "I_DID":
        console.log("Socket recevied : "+payload)
        var elemk = document.getElementById("divid")
        elemk.innerHTML = payload
        break
    }
  }

})

node_helper.js

var NodeHelper = require("node_helper");
var socketTestpython;
module.exports = NodeHelper.create({
  start: function() {
    socketTestpython=this;
  },
  
  socketNotificationReceived: function(notification, payload) {
    switch(notification) {
      case "TEST":
        console.log("notification : " + notification)
	socketTestpython.sendSocketNotification("I_DID",'hello');        
        break
    }
  },
}) 

npm start dev &

in terminal=>

pi@raspberrypi:~/Desktop/MagicMirror $ npm start dev &

@emrhssla which MM are u working in?

/home/pi/Desktop/Beauty (see its config/config.js
or
/home/pi/Desktop/Beauty/MagicMirror one? (see ITS config/config.js

they are different (u have MagicMirror installed INSIDE a MagicMirror folder)
to fix this, in /home/pi/Desktop/Beauty do

mv MagicMirror ..

now you will have

/home/pi/Desktop/Beauty
and
/home/pi/Desktop/MagicMirror

[sdetweil]

@emrhssla what is the error?

open a terminal window or ssh window

do

npm start dev &

node_helper output will show up in the terminal window

then on the mirror UI, developers window
select the console tab

note that the filenames are CASE sensitive
so you code should be in

mm/modules/MMM-TestPython

[emrhssla]

@sdetweil
in terminal, output is

pi@raspberrypi:~/Desktop/MagicMirror $ npm start dev &
[1] 1452
pi@raspberrypi:~/Desktop/MagicMirror $

magicmirror@2.7.1 start /home/pi/Desktop/MagicMirror
sh run-start.sh “dev”

after click,That’s all.
There are no errors, and console.log() is not visible from the terminal window.

@emrhssla i cut/pasted your code to create your module, added it to config.js
and it performs as expected…

i get in developers console

hello~hello~hello~hello~hello~hello~hello~hello~hello~hello~    MMM-Testpython.js:62
 Socket recevied : hello                                        MMM-Testpython.js:71

and in terminal window

notification : TEST

config entry

{
  module: "MMM-Testpython",
  disabled: false,
  position: "middle",
  config:{
    
  }
},

[sdetweil]

after the npm start &

press enter… you should get the prompt back, and can do any command

add this to your node module start function

  start: function() {
    socketTestpython=this;
    console.log(this.name + " node_helper started")    // < ---- add this

should see this in terminal window

MMM-Testpython node_helper started

i do

[emrhssla]

@sdetweil

[sdetweil]

@emrhssla that console output doesn’t make sense… cause u should have seen this line at least

Module helper loaded: MMM-Testpython

before the

Launching application 

show me your config.js

@emrhssla that doesn’t match with the terminal window output…

in terminal window only

Starting MagicMirror: v2.7.1
Loading config …

Initializing new module helper …
Module helper loaded: updatenotification   < ----

there are only two modules referenced…

never mind, two of mine don’t have position and work fine
delete ---------also, all modules require a position

[sdetweil]

this what I see on my startup in the terminal window, before the node_modules start outputing their text
