How to fix the streaming logic?

Question

Node.js

I use here this module for work with RSS. I took an example from there, everything works. But my 'readable' event fires many times when sending one request to the site. How can I make it so that the request is sent only once?
Tried to use stream.end(), but didn't work

const req = request('https://tjournal.ru/rss'),
      feedParser = new FeedParser();
req.on('response', function(res) {
  this.pipe(feedParser);
});

feedParser.on('readable', function() {
  var stream = this, item;
  if (item = stream.read()) {
    console.log(item.title, item.link);
  }
});

The event must fire many times, this is how streams work.
If you want to collect everything, and then do some action at the end, then here is an approximate solution:

var FeedParser = require('feedparser')
  , request = require('request');

var req = request('https://tjournal.ru/rss'),
      feedParser = new FeedParser();
req.on('response', function(res) {
  this.pipe(feedParser);
});

var titles = [], emitted = false

feedParser.on('readable', function() {
  var stream = this, item

  if (item = stream.read()) {
    titles.push(item.title)
  }

  !emitted && (emitted = true) && stream.on("end", function () {
    console.log(titles)
  })
})
