      in node_helper.js

      var NodeHelper = require("node_helper");
      const fs = require('fs')
      const path = require('path')
      // add require of other javascripot components here
      // var xxx = require('yyy') here
      
      module.exports = NodeHelper.create({
      
      
      	// handle messages from our module// each notification indicates a different messages
      	// payload is a data structure that is different per message.. up to you to design this
      	socketNotificationReceived(notification, payload) {
      		console.log(this.name + " received a socket notification: " + notification + " - Payload: " + payload);
      		// if config message from module
      		if (notification === "CONFIG") {
      			// save payload config info
      			this.config=payload
      			let p = path.resolve('.','modules',this.name,this.config.filename)
      			console.log("file="+p)
      			fs.readFile(p, (error,filedata)=> {
      			console.log("filedata="+filedata)
      			let data =JSON.parse(filedata)
      			this.sendSocketNotification('filedata', data)

        What do you meen by " need some trigger function"? is that in the node_helper.js or where should it be?

        modulename.js sends node_helper a socket notification w the module config info
        node_helper sends the data back as object

        Should I write some code in the modulename.js that call file read or do you mean that this is the place to make the compare?

          @bravooscar compare back in modulename.js, it needs to decide.

          trigger
          just say nothing happens in node helper without some event

          this should get the file contents and send to modulename.

          modulename.js sends socketNotification to helper w config info to start the process

            full node_helper.js above, tested, working
            need to get path to file in module folder (not current folder)

            sends object to module to make decisions on what to display

              It now works, I can get data into my new object.

              My new json file look like this:

              {
                "RecyclingDates": [
              { "Type": "House", "Date": "02.01.2021"},
              { "Type": "House", "Date": "08.01.2021"},
              { "Type": "House", "Date": "15.01.2021"},
              { "Type": "Glass", "Date": "22.01.2021"},
              { "Type": "Glass", "Date": "29.01.2021"},
              { "Type": "Glass", "Date": "05.02.2021"},
              { "Type": "Garden", "Date": "12.02.2021"},
              { "Type": "Garden", "Date": "19.02.2021"},
              { "Type": "Garden", "Date": "26.02.2021"},
              { "Type": "Garden", "Date": "05.03.2021"},
              { "Type": "Big", "Date": "12.03.2021"},
              { "Type": "Big", "Date": "19.03.2021"},
              { "Type": "Big", "Date": "26.03.2021"}
              ]
              }
              

              I get this object output:

              Object
              RecyclingDates: Array(13)
              0:
              Type: "House"
              Date: "02.01.2021"
              __proto__: Object
              1:
              Type: "House"
              Date: "08.01.2021"
              __proto__: Object
              2: {Type: "House", Date: "15.01.2021"}
              3: {Type: "Glass", Date: "22.01.2021"}
              4: {Type: "Glass", Date: "29.01.2021"}
              5: {Type: "Glass", Date: "05.02.2021"}
              6: {Type: "Garden", Date: "12.02.2021"}
              7: {Type: "Garden", Date: "19.02.2021"}
              8: {Type: "Garden", Date: "26.02.2021"}
              9: {Type: "Garden", Date: "05.03.2021"}
              10: {Type: "Big", Date: "12.03.2021"}
              11: {Type: "Big", Date: "19.03.2021"}
              12: {Type: "Big", Date: "26.03.2021"}
              length: 13
              

              I opend “0” and “1” in the object, so you can see how its stored in the object.

              How do I access these values in my module.js file. I hope to make a loop/compare of the array.
              My plan is to show different pictures according to the Type and if the Date is equale to current date.

                for( let entry of object.RecylingDates){
                  if (entry.Type ==='House'){
                      if(entry.Date==='........'){
                      }
                   }
                }
                

                you can use moment().format(???)
                where ??? is the layout of yiur date strings to get something for today, tomorrow…

                  I have this now, and this is working.

                  for(let type of Object.keys(obj)){
                  var date = obj[type];
                  console.log(type, date);
                  }
                  

                  This will show the correct type and date.
                  But I have something in mind, that look like this:

                  if date === currentdate {
                  picture=type+"Div"}
                  
                  ex:  
                  20.02.2021 === 20.02.2021 then var piture= "bigDiv"
                  

                  picture is then displayed.

                  but this have to be a loop, because there can be same dates but with different types(pictures)

                  Does this gives any meaning? its hard to descripe, but I’m realy glad for all the help I get.

                    @bravooscar as i said u can use the js library moment().format(‘dd.mm.yyyy’) to get today in string to compare

                    see the online doc for exact syntax

                      That I know. I allready have the actual date and the date from the array,
                      Im unsure of how to get all the dates and all the types from the array, so if there are more of the same dates, then there are more types taht has to be displayed.

                        @bravooscar u are usuing object.keys() to.loop.over the array this only gives u unique entries, house, …

                        i would use my loop, which covers every entry.
                        i dont understand your file data
