Simple Node application for parsing webpage articles according configuration. Notify about new articles by email.

My son goes to kindergarten. The kindergarten is very active on their website and regularly informs parents. So in order not to lose any news, I created this script.
The idea was to make it as simple as possible without so many features. I didn't want to use a database, so the data about the discovered articles is stored in a file.
In the News and Articles I am interested about TITLE, Initial TEXT and HREF to detailed article

<div id='content'>
  <div class='row justify-content-center dlazdice'>
    <div class='nadpis'>AKTUALITY</div>
    <div class='col-md-3 text-box-obsah'>
      <h2>Article title 01</h2>
      <p>Article text 01</p>
      <p>
        <a class='btn btn-secondary tlacitko' href='index.php?p=some-page-01' role='button'>Show more...</a>
      </p>
    </div>
    <div class='col-md-3 text-box-obsah'>
      <h2>Article title 02</h2>
      <p>Article text 02</p>
      <p>
        <a class='btn btn-secondary tlacitko' href='index.php?p=some-page-02' role='button'>Show more...</a>
      </p>
    </div>
  </div>
</div>

Requires config.json file in the ROOT

  "parseUrl": [
    {
      "name": "my-url-name-1",
      "link": "https://example-domain.com"
    },

      "name": "my-url-name-2",
      "link": "https://example-domain.com/articles/"
    }
  ],
  "parseUrlSelectors": {
    "main": "div#content div.text-box-obsah",
    "articleTitle": "h2",
    "articleText": "p",
    "articleDetailHref": "href"
