Challenge: URL Shortener Microservice

Link to the challenge:

Welcome, furko.

I am not sure if this is the problem, but you have a bit of a conflicting pattern here:

const newUrl = new Url({
          original_url: postedUrl,
          short_url: urlIndex++
        })
        newUrl.save(function (error, url) {

You are saving the short_url property based on the global variable urlIndex. This is a bad idea, because every time your app refreshes, the urlIndex will refresh, but the database will still have all the old values. Thus, you will have duplicate values.


Actually, I believe your issue is here:

dns.lookup(postedUrl.substring(8),

dns.lookup expects only the domain name as the first argument. That means, in this url https://freecodecamp.org/example/location

  • you are passing this: freecodecamp.org/example/location
  • this is the domain name: freecodecamp.org

Hope this helps
