      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);
          
        },
      })

        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

          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]

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

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

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

                      "name": "MMMTestpython",
                      "description": "samples",

                    }
                    
                    

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