Url shortening app using Vanilla JS

What are you most proud of, and what would you do differently next time?

Knowing that I can still comfortably write vanilla js, at least to be able to build a webpage with it.

I also added a tweak; a delete button to remove a link from user's local storage.

What challenges did you encounter, and how did you overcome them?

I had a lot of challenges with cors errors using the suggested API, but I was able to find an alternative, maybe temporary for now, as it doesn't accept every kind of links.

What specific areas of your project would you like help with?

I'd like help with getting rid of the cors errors for the cleanURI API, thank you.
