Return related YouTube track for AutoPlay (ES8)

relatedYoutube.js

const cheerio = require('cheerio')

async function relatedTrackAuto () {
  let request = require('async-request')

  try {
    let response = await request(process.argv[2])

    var $ = await cheerio.load(response.body)

    let urlres = await $(`.video-list>.video-list-item>.content-wrapper>.content-link`).attr(`href`)

    let finalres

    if (urlres === undefined) {
      finalres = 'https://www.youtube.com/watch?v=dQw4w9WgXcQ'
      console.log(`Undefined URL. Defaulting to Rick Roll!`)
      return finalres
    } else {
      finalres = 'https://www.youtube.com' + urlres

      return finalres
    }
  } catch (error) {
    console.log(error)
    return null
  }
}

relatedTrackAuto()
  .then(function (result) {
    console.log(result)
  })

Notes

• Two options: as it is above, with https://gist.github.com/shikhir-arora/00749ad27f62c9c0db18ee1548a41244#file-relatedyoutube-js-L7 on line 7, the script will expect a valid URL (any URL) as a command argument in a terminal. The usage is node relatedYoutube.js "http://youtube.link.here" which will return the related song URL.

• Removing line 7 and changing it back to simply let response = await request('URL_HERE') -- can use whatever fits the need to pass in the URL field.
  process.argv[2] just makes it easy to do quick terminal commands with any URL before integration.

• async-request to make our lives easier. I have an updated version which can be installed manually or with
  { "async-request": "github:shikhir-arora/async-request" } as a dependency in your package file. Here is my fork: https://github.com/shikhir-arora/async-request which just ensures things are up-to-date for this use.
  (it is just a basic extension of request and saves a few lines of code).

• Code is written in StandardJS -style for Node v8+ and is all ES8. Linted and Syntax verified against my standard ES8/Node config
