node_helper. But need to find different approach.

const NodeHelper = require("node_helper");
const cheerio = require("cheerio");
const request = require('request');
var self;
module.exports = NodeHelper.create({

    start: function () {
        self = this;
        console.log("Starting node_helper for: " + this.name);
    },

    getData: function () {
        
		const url = 'https://wol.jw.org/hr/wol/h/r19/lp-c';
        request({
            url: url,
            method: 'GET'
        }, (error, response, body) => {
            if (error) {
                return console.error("ERROR: ",error)
            }
            if (!error && response.statusCode == 200) {
            var $ = cheerio.load(body);
            //console.log($.html());
            const data = $('div[class="tabContent"]').first();//   

            let header = $(data).find('h2').text();
            let title = $(data).find('p').first().text();
            let textData = $(data).find('div.pGroup>p').text();
            //console.log(header,title,text);
            var recivedData = {
                header,
                title,
                textData
            }
			//console.log('recivedData: ',recivedData);
            
			self.sendSocketNotification('TEXT_RESULT', recivedData);
			}
        });
    },

    socketNotificationReceived: function (notification, payload) {
     var self = this;
        if (notification === 'GET_TEXT_DATA') {
            //console.log(notification,payload);
			self.getData();
        }
    },
});

MMM-Dnevni_citat.js. getDom need some styling.

Module.register("MMM-Dnevni_citat", {
    defaults: {
        updateInterval: 10 * 60 * 1000, //  minute ,seconds ,milliseconds
        //retryDelay: 5000          // not needed for now
    },
    start: function () {
        Log.info("Starting module: " + this.name);
        requiresVersion: "2.1.0";
        this.loaded = false;
        this.scheduleUpdate();

    },
    scheduleUpdate: function () {
        setInterval(() => {
            this.getData();
        }, this.config.updateInterval);
        this.getData();
    },
    getData: function () {
        console.log(' GET_TEXT_DATA ', this.config)
        this.sendSocketNotification('GET_TEXT_DATA', this.config);
    },
    socketNotificationReceived: function (notification, payload) {
        if (notification === "TEXT_RESULT") {
            this.textDataRecived = payload;
            console.log(this.textDataRecived);
            this.loaded = true;
        }
        this.updateDom();

    },

    getDom: function () {
        var wrapper = document.createElement("div");

        if (!this.loaded) {
            wrapper.innerHTML = "LOADING";
            return wrapper;
        }
        if (this.loaded) {
            var header = document.createElement("header");
            header.innerHTML = this.textDataRecived.header;
            wrapper.appendChild(header);

            var table = document.createElement('tr');
            table.classList.add("xsmall", "normal");
            var title = document.createElement('tr');
            title.innerHTML = this.textDataRecived.title;
            table.appendChild(title);
            var textData = document.createElement('tr');
            textData.innerHTML = this.textDataRecived.textData;

            table.appendChild(textData);
            table.appendChild(title);
            wrapper.appendChild(table);

        }
        return wrapper;
    },
});

config.js

		{    module: "MMM-Dnevni_citat",
             position: "middle_center"

@Amoniak
This should fix the problem with loading text for current Date.
node_helper:

const NodeHelper = require("node_helper");
const cheerio = require("cheerio");
const request = require('request');
var self;
const ur = 'https://wol.jw.org/wol/dt/r19/lp-c';

module.exports = NodeHelper.create({

    start: function () {
        self = this;
        self.browser
        console.log("Starting node_helper for: " + this.name);
    },

    getData: function () {
        var self = this;
        var url = self.setURL();
        request({
            url: url,
            method: 'GET'
        }, (error, response, body) => {
            if (!error) { 
                var result = JSON.parse(body);
                var contentData = result.items[0].content;
                var $ = cheerio.load(contentData);
                //console.log("cheerio:  ", $.html());
                var header = $('html>body>header>h2').text();
                var title = $('p').first().text();
                var textData = $('p').first().next().text().replace(/(\r\n|\n|\r)/gm, "");
                var recivedData = {
                    header,
                    title,
                    textData
                };
                //console.log(recivedData);    
				self.sendSocketNotification('TEXT_RESULT', recivedData);
            }
            if (error) { 
                console.log(error);
            }
        });

    },

    setURL: function () {
        console.log("ur old: ", ur);
        var utc = new Date().toJSON().slice(0, 10).replace(/-/g, '/');
        var newURL = ur.concat("/").concat(utc);
        return newURL
    },


    socketNotificationReceived: function (notification, payload) {
        var self = this;
        if (notification === 'GET_TEXT_DATA') {
            self.getData();
        }
    },
});

@lolo
thank you, I’ll try right now

[Amoniak]

@lolo there it is.
many, many, many thanks. and thanks for adding explanations

[lolo]

@Amoniak you’re welcome.
Just delete the second appendChild in MMM-Dnevni_citat.js

            var table = document.createElement('tr');
            table.classList.add("xsmall", "normal");
            var title = document.createElement('tr');
            title.innerHTML = this.textDataRecived.title;
            table.appendChild(title);
            var textData = document.createElement('tr');
            textData.innerHTML = this.textDataRecived.textData;

            table.appendChild(textData);
            table.appendChild(title);        // delete this one
            wrapper.appendChild(table);

I added twice,my mistake.

[e199504]

@amoniak how did you fix the black screen? I am getting the same error

[sdetweil]

@e199504 is this after install?

did u do the npm install in the module folder?

[e199504]

@sdetweil in the reeadme file it did not say to go inside the module and use npm install but once I did it started working.
thank you

[sdetweil]

@e199504 yes. it seems many authors forget to write that step.

general rule. look for a package.json file.
if present, run the npm install
