Shipped this project!
I made a URL Shortener service that takes links and makes them short and easy to share.
The tough part was figuring out what to do when things did not go as planned like when two links wanted to use the short code and making sure everything was safe and secure especially when links had passwords and needed special permission. After trying a lot of things and making mistakes I finally got it working well by trying again when things failed using special codes to keep things safe and checking everything carefully.
My URL shortener also lets people make their special codes count how many times a link is clicked and it has a simple interface that looks like a computer terminal and even a special page for administrators to manage people and links.
I am pretty happy, with how my URL shortener turned out.
