Is there a way to stop reading the feed?

[snaka]

Sorry for the silly question. (I'm not familiar with stream)

I wonder whether it is possible to stop reading before end of feed reached.

I had tried code below.

var myProductName = "feedParserDemo"; myVersion = "0.4.3";

const request = require ("request");
const FeedParser = require ("feedparser");

//const urlTestFeed = "http://www.guardian.co.uk/world/usa/rss";
const urlTestFeed = "http://feeds.backspace.fm/backspacefm";   // <-- ### CHANGE FEED URL ###

function getFeed (urlfeed, callback) {
        var req = request (urlfeed);
        var feedparser = new FeedParser ();
        var feedItems = new Array ();
        req.on ("response", function (response) {
                var stream = this;
                if (response.statusCode == 200) {
                        stream.pipe (feedparser);
                        }
                });
        req.on ("error", function (err) {
                console.log ("getFeed: err.message == " + err.message);
                });
        feedparser.on ("readable", function () {
                try {
                        var item = this.read (), flnew;
                        if (item !== null) { //2/9/17 by DW
                                feedItems.push (item);
                                }
                        feedparser.end();    // <--- ### ADD THIS LINE ###
                        }
                catch (err) {
                        console.log ("getFeed: err.message == " + err.message);
                        }
                });
        feedparser.on ("end", function () {
                callback (undefined, feedItems);
                });
        feedparser.on ("error", function (err) {
                console.log ("getFeed: err.message == " + err.message);
                callback (err);
                });
        }

console.log ("\n" + myProductName + " v" + myVersion + ".\n");
getFeed (urlTestFeed, function (err, feedItems) {
        if (!err) {
                function pad (num) {
                        var s = num.toString (), ctplaces = 3;
                        while (s.length < ctplaces) {
                                s = "0" + s;
                                }
                        return (s);
                        }
                console.log ("There are " + feedItems.length + " items in the feed.\n");
                for (var i = 0; i < feedItems.length; i++) {
                        console.log ("Item #" + pad (i) + ": " + feedItems [i].title + ".\n");
                        }
                }
        });

Then result was like below.

feedParserDemo v0.4.3.

There are 1 items in the feed.

Item #000: #254: <item title .... >

This output is expected.
But , It is kept waiting long until the program ends.

Is there a proper way to stop reading the feed?
