URL shortening API landing page

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

This is the first time I use Tailwind CSS to do projects, it cost more time, it's different but similar with writing vanilla css, and just writing utility class names is new, atomic and technical. Also, we need to fetch data of API from server side using POST request, which is also new to me. The output is great and I am satisfied with it.

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

Fetch data from API using Post request is usually backend job, it's not easy to do without a backend framework, and I address it by using classic XMLHttpRequest and corsproxy prefix, it worked well.
