Example of using feedparser (https://github.com/danmactough/node-feedparser) with ES6 on node.js >= 4.0.0

testing_feedparser_ES6.js

'use strict'

const FeedParser = require('feedparser')
const request = require('request')

let req = request('https://github.com/danmactough.atom')
let parser = new FeedParser()

req.on('error', (err) => {
  // handle request error
  console.log(err)
})

req.on('response', (res) => {
  // check if status code is not correct
  if (res.statusCode !== 200) {
    return req.emit('error', new Error('Bad status code'))
  }
  // if the res is correct, when can pipe the response
  req.pipe(parser) // pipe response to feedparser
})

parser.on('error', (err) => {
  // handle parser error
  console.log(err)
})

parser.on('end', () => {
  // handle that we've finished reading articles
  console.log('End parsing')
})

parser.on('readable', () => {
  let item = parser.read()
  let meta = parser.meta // get the metadata of the feed
  while (item) {
    // do whatever you want with the item
    console.log(item)
    // get the next item, if none, then item will be null next time
    item = parser.read()
  }
})
