MMM-Testpython

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
    }
  },
  
})

node_helper.js

var NodeHelper = require("node_helper");
var {PythonShell} = require('python-shell');

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

The notification I_DID in node_helper.js was well communicated and executed. However, the console in node_helper.js is not output…
What is the problem?

var NodeHelper = require("node_helper");
var {PythonShell} = require('python-shell');

module.exports = NodeHelper.create({
  start: function() {},
  
  socketNotificationReceived: function(notification, payload) {
    Log.log(this.name + " received a socket notification: " + notification + " - Payload: " + payload);
    
  },
})  

Even a simple node_help.js example does not run.

@emrhssla said in Even a simple node_help.js example does not run.:

Log.log(this.name + " received a socket notification: " + notification + " - Payload: " + payload);

as I posted in the other topic, the node_helper content would be displayed in the terminal window
where u started MM…

also

Log.log will not work in node helper. that is only available in the module.js

@emrhssla said in Even a simple node_help.js example does not run.:

also, you need to install the python-shell component…

need a package.json file

{
  "name": "MMM-Testpython",
  "description": "sample",
  "version": "0.0.1",
  "dependencies": {
    "python-shell": "latest"
  }
}

and then run

npm install

in the module folder

the updated node_helper.js is

var NodeHelper = require("node_helper");
var {PythonShell} = require('python-shell');

module.exports = NodeHelper.create({
  start: function() {},
  
  socketNotificationReceived: function(notification, payload) {
    console.log(this.name + " received a socket notification: " + notification + " - Payload: " + payload);
    
  },
})

and produces this message in the terminal window, when the UI component is clicked

MMM-Testpython received a socket notification: TEST - Payload: [object Object]

@sdetweil

Is it normal for these errors to occur?
/modules/MMM-Testpython/package.json

var NodeHelper = require("node_helper");
//var {PythonShell} = require('python-shell');

module.exports = NodeHelper.create({
  start: function() {},
  
  socketNotificationReceived: function(notification, payload) {
    console.log(this.name + " received a socket notification: " + notification + " - Payload: " + payload);
  },
})   

omg…

[sdetweil]

@emrhssla sorry, I had a name of “sample” when I did it. I guess the - is not allowed

[sdetweil]

@emrhssla that log is only from the module file. Not node_helper

@sdetweil

{
  "name": "MMMTestpython",
  "description": "samples",
  "version": "0.0.1",
  "dependencies": {
    "python-shell": "latest"
  }
}

Do I have to change it like this and install it again? npm install

[sdetweil]

@emrhssla I don’t understand… mine worked perfectly

package.json

{
  "name": "MMM-Testpython",
  "description": "sample",
  "keywords": [
    "   none"
  ],
  "version": "0.0.1",
  "dependencies": {
    "python-shell": "latest"
  }
}

Looks like your system doesn’t have python installed.
