read csv-data and put it in an array

[sdetweil]

sorry, forgot one thing i saw in node helper,… need to move everything in the start function to the socketNotification section… at start time the module is not up yet, so the message goes nowhere

socketNotificationReceived(notification, payload) {		
	var self = this		
		// if config message from module
		if (notification === "CONFIG") {
			// save payload config info
			this.config = payload;
			var self = this;
			console.log("Starting module helper: " + this.name);

			// convert the csv-file into a JSON-String
			const csvFilePath = this.path + '/birthdays.csv';
			csv()
			.fromFile(csvFilePath)
			.then((jsonObj)=>{      
				birthdaysArray = JSON.stringify(jsonObj);
				
				// for debugging only
				console.log("birthdaysArray: ", JSON.stringify(birthdaysArray));
				
				// send data to [modulname].js
				self.sendSocketNotification("have data", jsonObj);
			})	
		}
		else if(notification === "????2") {
		}
	},

also, by moving it here, all you have to do is fix the code, save and then refresh the page… don’t have to restart MM

start is now empty

	start() {
	
	},

ok, nothing changed and i don’t see any messages of “HAVEDATA” (changed it in both files to big letter without space). i only see the header “Geburtstage” … :-(
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() {

	},
/*	
	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) {				

		var self = this;
		console.log("Starting module helper: " + this.name);

		// convert the csv-file into a JSON-String
		const csvFilePath = this.path + '/data/birthdays.csv';
		csv()
		.fromFile(csvFilePath)
		.then((jsonObj)=>{      
			birthdaysArray = JSON.stringify(jsonObj);
			
			// send data to [modulname].js
			self.sendSocketNotification("HAVEDATA", jsonObj);
		})		

		// 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") {
	
		}
	},
});

maye change this part, cause i never need this variable birthdaysArray:

.then((jsonObj)=>{      
			birthdaysArray = JSON.stringify(jsonObj);

perlchamp.js:

Module.register("perlchamp", {

	defaults: {
		language: "de",
		dimmEntries: true   // true: dims entries and the associated 
							//       symbol when the date has expired.
							// false: delete entries and the associated 
							//        symbol when the date has expired.
	},
	
	active_birthdays: {
		
	},


	init: function(){
		Log.log(this.name + " is in init!");
	},

	start: function(){
		Log.log("Starting module: " + this.name);

		// Set locale
		moment.locale(config.language);
	},

	loaded: function(callback) {
		Log.log(this.name + " is loaded!");
		callback();
	},

	// return list of other functional scripts to use, if any (like require in node_helper)
	getScripts: function() {
		return	["moment.js"];
	}, 

	// return list of stylesheet files to use if any
	getStyles: function() {
		return 	[this.data.path + "/css/perlchamp.css"];
	},


	// only called if the module header was configured in module config in config.js
	getHeader: function() {
		return this.data.header;
	},

	// messages received from other modules and the system (NOT from your node helper)
	// payload is a notification dependent data structure
	notificationReceived: function(notification, payload, sender) {
		// once everybody is loaded up
		if(notification==="ALL_MODULES_STARTED"){
			// send our config to our node_helper
			this.sendSocketNotification("CONFIG",this.config);
		}
		if (sender) {
			Log.log(this.name + " received a module notification: " + notification + " from sender: " + sender.name);
		} else {
			Log.log(this.name + " received a system notification: " + notification);
		}
	},
	
	// 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) {

		if(notification === "HAVEDATE"){
			Log.log(this.name + " received a socket notification: " + notification + " - Payload: " + payload);
			
			var now = moment();
			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);
				
				// 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(this.active_birthdays[birth_date] == undefined){
           
						//  create the holder for its info (array of 
						//		names) in the hash
						this.active_birthdays[birth_date] = [];
					}
					// save the persons name on the list
					this.active_birthdays[birth_date].push(birthday.name);
				}
			}
     
			// tell MM to call and get our content
			self.updateDom();
		}     			
	},

	// system notification your module is being hidden
	// typically you would stop doing UI updates (getDom/updateDom) if the module is hidden
	suspend: function(){

	},

	// system notification your module is being unhidden/shown
	// typically you would resume doing UI updates (getDom/updateDom) if the module is shown
	resume: function(){

	},

	// this is the major worker of the module, it provides the displayable content for this module
	getDom: function() {
		var wrapper = document.createElement("div");

		for(var birthday of Object.keys(this.active_birthdays)){
			for(var name of this.active_birthdays[birthday]){
				var m = document.createElement('div');
				m.innerText = birthday + ' '+ name;
				wrapper.appendChild(m);
			}
		}

		// pass the created content back to MM to add to DOM.
		return wrapper;
	}
})

please have an eye on the getDom-sektion.

no… it will do the thig every time a notifcation comes in, only want it when the module sends down a message (say it is alive)

in node_help you are sending this “HAVEDATA”
and in module you are looking for this if(notification === “HAVEDATE”){

add a var self = this to start of socketNotificationReceived() and getDom()

[sdetweil]

@Perlchamp said in read csv-data and put it in an array:

if(birth_date.startOf(‘day’)

also should be

if(birth_date_moment.startOf('day')

comparing moments, not strings! oops

[Perlchamp]

only the header i see, BUT now i see the terminal-message “HAVEDATA” but an error, too:

[sdetweil]

@Perlchamp open the developers window, ctrl-shift-i on the mirror screen,
select console tab,
put perl in the filter field

select the sources tab, navigate the left nav tree,. to modules/perlchamp/perlcmap.js

find the socketnotificationreceived

click the number in the left column, hit f5 (refresh) on keyboard

code should stop at the line you clicked

in the right pane, top there is a blue arrow (resume executing) and a top half of a globe, stop on next )instruction)

[Perlchamp]

before looking in dev: i saw the following:

var birth_date_moment = moment(birth_date + now.getYear(),"DD.MMYYYY");

change to DD.MM.YYYY (point between MM and YYYY) ?

[sdetweil]

@Perlchamp no, cause we extract dd.mm from the info provided in file…

oh, the substring should be 0,5, not 0,4

var birth_date = birthday.birth.substring(0,5);

[Perlchamp]

error => now.getYear() is not a function

[sdetweil]

@Perlchamp yeh, sorry, rememeber just off the top of my head…
date uses that …
moment its just year()

var birth_date_moment = moment(birth_date + now.year(),“DD.MMYYYY”);
