      @Perlchamp ok, went to numbers, SO much easier!!

      var today_day_month = moment().format("DD.MM")
      // today would be "30.04"
      // tomorrow will be "01.05"
      // loop thru the array of birthday info from file, one 'row' per birthday
      
      for(var birthday of birthday_info) {
           if( (birthday.birth.startsWith(today_day_month)) {
               // this birthday is for today
                  console.log(" birthday on "+ today_day_month+" is for "+birthday.name);
           } 
      }

            thanks, but now i’m a little bit confused, because my master problem will be, to reorg the array, to combine people with the same date of birth in as list in one row with the day of birth. but let me try …

                … and I’m very grateful to you for that. I learn from your messages every time. I think it’s great that there are people like you. that also costs time (apart from health, the most important thing in life). Thanks again for that!

                  hi sam,
                  i have a major problem, that i don’t understand. this is my code in node_helper.js:

                  var NodeHelper = require("node_helper");
                  var moment = require("moment");
                  
                  // add require of other javascripot components here
                  // var xxx = require('yyy'); here
                  const csv = require("csvtojson");
                  var birthdaysArray = [];
                  
                  
                  module.exports = NodeHelper.create({
                  
                  	init(){
                  		console.log("init module helper perlchamp");
                  	},
                  
                  	start() {
                  		console.log("Starting module helper: " + this.name);
                  		//	console.log("Pfad zur csv-Datei: " + this.path + "/data/birthdays.csv");
                  		
                  		const csvFilePath = this.path + '/data/birthdays.csv';
                  		csv()
                  		.fromFile(csvFilePath)
                  		.then((jsonObj)=>{      
                  			birthdaysArray = JSON.stringify(jsonObj);
                  			console.log("birthdaysArray: " + birthdaysArray);
                  
                  			var today_day_month = moment().format("DD.MM");
                  			var today_month = moment().format("MM");
                  		})
                  		
                  		console.log("birthdaysArray #2: " + birthdaysArray);
                  		
                  		// moment.js
                  		moment.locale(config.language);  // set locale
                  		console.log("aktuelle Zeit: " + moment().format('Do MMMM YYYY, hh:mm:ss'));
                  		console.log("aktueller Monat(Zahl): " + moment().format('MM'));
                  		console.log("aktueller Monat(Text): " + moment().format('MMM'));
                  		console.log("aktueller Tag(Zahl mit führender Null): " + moment().format('DD'));
                  		console.log("aktueller Tag(Text): " + moment().format('dddd'));
                  		console.log("aktueller Tag(Abkürzung): " + moment().format('dd'));
                  		console.log("aktuelles Jahr(Zahl): " + moment().format('YYYY'));
                  	},
                  
                  	stop(){
                  		console.log("Stopping module helper: " + this.name);
                  	},
                  
                  	// 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);
                  		console.log(this.name + " received a socket notification: " + birthdays);
                  		// if config message from module
                  		if (notification === "CONFIG") {
                  			// save payload config info
                  			this.config=payload
                  			// wait 15 seconds, send a message back to module
                  			setTimeout(()=> { this.sendSocketNotification("message_from_helper"," this is a test_message")}, 15000)
                  		}
                  		else if(notification === "????2") {
                  		}
                  
                  	},
                  });
                  
                  

                  why returns

                  console.log("birthdaysArray #2: " + birthdaysArray);
                  

                  nothing.

                  many thanks in advance

                    should be

                    console.log(this.name + " received a socket notification: " + birthdaysArray);
                    

                    of course. couldn’t edit it, because of spam-message from board …

                      welcome to programming with a asyncronous libraries

                      csv().fromFile(csvFilePath) starts a ‘long’ operation,
                      going out to disk, reading in the data, and converting it to json from spreadsheet… (long is milliseconds)

                      the processor should not wait, so it does not, and the next instruction AFTER the start of the fromFile()
                      is console.log("birthdaysArray #2: " + birthdaysArray);

                      	// moment.js
                      	moment.locale(config.language);  // set locale
                      	console.log("aktuelle Zeit: " + moment().format('Do MMMM YYYY, hh:mm:ss'));
                      	console.log("aktueller Monat(Zahl): " + moment().format('MM'));
                      	console.log("aktueller Monat(Text): " + moment().format('MMM'));
                      	console.log("aktueller Tag(Zahl mit führender Null): " + moment().format('DD'));
                      	console.log("aktueller Tag(Text): " + moment().format('dddd'));
                      	console.log("aktueller Tag(Abkürzung): " + moment().format('dd'));
                      	console.log("aktuelles Jahr(Zahl): " + moment().format('YYYY'));
                      

                      and the start function runs out of things to do and returns back to MM…

                      sometime later , the fromFile() will complete, and call the .then() routine with the data

                      (jsonObj)=>{      
                      			birthdaysArray = JSON.stringify(jsonObj);
                      			console.log("birthdaysArray: " + birthdaysArray);
                      
                      			var today_day_month = moment().format("DD.MM");
                      			var today_month = moment().format("MM");
                      		}
                      

                      so, if you need to wait for the data(to prints is content) , then the operations would be inside the .then() handler.

                        ok, thanks. to move the code is not heavy ;-) … i’ve found a snippte to sort my birthdaysArray, but that doesn’t match :

                        		const csvFilePath = this.path + '/data/birthdays.csv';
                        		csv()
                        		.fromFile(csvFilePath)
                        		.then((jsonObj)=>{      
                        			birthdaysArray = JSON.stringify(jsonObj);
                        			console.log("birthdaysArray: " + birthdaysArray);
                        			
                        		var result = Object.entries(birthdaysArray.reduce((a, {birth, name}) => {
                        			const day = +birth.split('.')[0];
                        			a[day] = [...(a[day] || []), name];
                        			return a
                        		}, {})).map(([day, name]) => ({day, name})).sort((a, b) => +a.day - b.day)
                        		console.log("sorted birthdays : " + result);
                        
                        		var today_day_month = moment().format("DD.MM");
                        		var today_month = moment().format("MM");
                        		})
                        
                        

                        now i’m looking for another one. is the birthdaysArray a json-Array or a javascript-array or … someone told me, it’s an object-Array and that this has nothing to do witch json … but: csvtojson, so …
