Our config contains several URLs and they are all strings (frontendUrl, databaseUrl, serverUrl, apiUrl, etc.). Whenever we want to do something with them, we call new URL and go from there.

Why not create URL objects as soon as possible and just save those inside the config? Like this

  // ...
  databaseUrl: URL;
  frontendUrl: URL;
  serverUrl: URL;

Benefits:

• We'd have a much easier time parsing the URL once and then working with URL objects than we do calling new URL in a bunch of places.
• It solves all problems described in Have a proper type for URLs we validated #3359.
• It would probably benefit our users too.

The task:

• Decide whether this makes sense (think about how it affects users).
• Consider the other possibility: Have a proper type for URLs we validated #3359
• If the change is viable, implement it.
