module that displays a certain text from a website, the text on the website is updated daily

@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();
        }
    },
});

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.

@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
