i can’t find … so everything’s right ?

Perlchamp

yes, i understood. here’s my perlchamp.js (only socketNitificationReceived)

	// messages received from from your node helper (NOT other modules or the system)
	// payload is a notification dependent data structure, up to you to design between module and node_helper
	socketNotificationReceived: function(notification, payload) {
		Log.log(this.name + " received a socket notification: " + notification + " - Payload: " + payload);
		if(notification === "message_from_helper"){
			this.config.message = payload;
			// tell mirror runtime that our data has changed,
			// we will be called back at GetDom() to provide the updated content
			this.updateDom(1000)
		}

		if(notification === "have data"){

			Log.log(this.name + " received a socket notification: " + notification + " - Payload: " + payload);
			
			var now = moment()
			var active_birthdays={}

			for( var birthday of payload) {
				// get 1st 5 chars of birthdate, thru month
				// we will use this as the key in the hash
				var birth_date = birthday.birth.subString(0,4)
				
				// for debugging only
				Log.log("Tag.Monat :", birth_date)
				
				// get the birthday as a moment in this year, for comparing
				var birth_date_moment = moment(birth_date + now.getYear(),"DD.MMYYYY")

				// u can add days to a moment object and then compare 
				//     if the birthdate is before that date (and after now)
				//     so within the next xx days

				// if the date is the same or later, don't use time of day
				if(birth_date.startOf('day').isSame(now.startOf('day')){

					// birthday is in this month
					// check the hash if we've seen anything for today yet
					// if we haven't see this date yet
					if(active_birthdays[birth_date] == undefined){
           
						//  create the holder for its info (array of 
						//		names) in the hash
						active_birthdays[birth_date] = []
					}
					// save the persons name on the list
					active_birthdays[birth_date].push(birthday.name)
				}
			}
     
			// tell MM to call and get our content
			self.updateDom();
		}     			
},

Perlchamp

// send data to [modulname].js
self.sendsocketNotification("have data", birthdaysArray)

i have found a typing error. Socket instead socket. if i than change self. to this. no errror messages will displayed. but still black screen.
maybe i did not understand how to handle the getDom-section … i will still try …
but:
i see no notification in the terminal. ‘have data’ should actually appear there, shouldn’t it ?

Perlchamp

this is the actual 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");

		moment.locale(config.language);  // set locale
		
		// convert the csv-file into a JSON-String
		const csvFilePath = this.path + '/data/birthdays.csv';
		csv()
		.fromFile(csvFilePath)
		.then((jsonObj)=>{      
			birthdaysArray = JSON.stringify(jsonObj);
			
			// for debugging only
			//console.log("birthdaysArray: ", birthdaysArray);
			
			// send data to [modulname].js
			self.sendsocketNotification("have data", birthdaysArray)

			// loop thru the array of birthday_info from file (jsonObj),
			// one 'row' per birthday
		
		})		
	},
	

	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) {				
		// 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") {
		}
	},
});

i got an error-message :

[2020-05-01 23:21:12.072] [WARN]   Unhandled rejection ReferenceError: self is not defined
    at /home/dirk/MagicMirror/modules/perlchamp/node_helper.js:34:4

i think this could be the problem:

// send data to [modulname].js
self.sendsocketNotification("have data", birthdaysArray)

i tried “this.” and without “self.” and “this.” but nothing changed. now i’m searching in the web, maybe i will found some answers ;-)

Perlchamp

ok, thank you sam.
Now I have to process the whole thing first, otherwise my head will burst ;-) …

Perlchamp

if i run :

		for(var birthday of birthdaysArray) {
			if(birthday.birth.startsWith(today_day_month)) {
				// this birthday is for today
				console.log(" birthday on "+ today_day_month+" is for "+birthday.name);
			} 
		}

than i get the following error-messages:

I was probably happy too early ;-( … shit happens.

Perlchamp

so i’m bloody happy :

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 result = Object.entries(jsonObj.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");
		})
		
	},

	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: " + birthdaysArray);
		// 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") {
		}

	},
});

so now I just have to manage to filter out the people from the complete csv-file who have their birthday in the current month …

Perlchamp

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 …

Perlchamp

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

should be

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

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

Perlchamp

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
