http = require 'http'
url = require 'url'

entry_url = 'http://letsrevolutionizetesting.com/challenge.json'

recurse = (url_string) ->
  console.log '\nfollowing...', url_string

  url_obj = url.parse url_string

  return http.get
    host: url_obj.host
    port: 80
    path: url_obj.path
    headers:
      'Accept': 'application/json'
  , (response) ->
    response.setEncoding 'utf8'

    response.on 'data', (body) ->
      body = JSON.parse body

      if body.follow?
        recurse body.follow
      else
        console.log "We've reached the bottom of the rabbit hole!", body

recurse entry_url
