I am trying to make a slight modification to a module that was discussed in this forum post:
https://forum.magicmirror.builders/topic/555/txt-file-include

This module does an excellent job of displaying the contents of a text file (and also seems to support some html formatting). However, when displaying this you see large spaces between each new line of text. I would love it if there is some way to alter this and have more “normal” spacing between each line. Can anyone help with this?

below is the current contents of the following files…

MMM-Text.js:

Module.register("MMM-Text",{
    defaults: {
    updateInterval: 30 * 60 * 1000 //reads the file every 30 mins
},

start: function(){
    this.sendSocketNotification('START', this.config);
},

socketNotificationReceived: function(notification, payload) {
    if(notification === 'DATA'){
        this.dataFile = payload;
        this.updateDom();
    }
},

getDom: function(){
    var wrapper = document.createElement('div');
    if(this.dataFile){
        wrapper.innerHTML = this.dataFile;
    } else {
        wrapper.innerHTML = 'No data';
    }
    return wrapper;
}
});

node_helper.js:

const NodeHelper = require("node_helper");
const fs= require("fs");

module.exports = NodeHelper.create({
    socketNotificationReceived: function(notification, payload) {
    if(notification === 'START'){
        this.config = payload;
        this.readData();
        setInterval(() => {
            this.readData();
        }, this.config.updateInterval);
    }
},

readData: function(){
    //to read a file to do the following
    fs.readFile('/home/pi/MagicMirror/modules/MMM-Text/mmText.txt', 'utf8', (err, data) => {
        if (err) throw err;
        this.sendSocketNotification('DATA', data);
    });
}
});

example of mmText.txt (the file that will be displayed):

< font size="3" >
Attic: 85°<br />
Crawlspace: 77°<br />
Den: 77°<br />
Rack: 71°<br />
< /font >
