Url Shortener landing page using react and express js

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

Id start by testing how it would behave before making all the css. Other than that, Im proud because I never used a backend solution to process an api

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

The API needing to be processed through my own backend was a real difficulty. I inspired myself watching videos and making me understand why and how I needed to use it.

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

Id just like to see the best practices to make a better code
