URL Shortener

Every web developer should write an URL Shortener, and here's mine:

What does stand out my shortener from the others? Lets see.

• It Uses MD5 hash of the original URL for a short link.
• It Starts with the first five symbols of the hash.
• If that's taken, it keeps adding more symbols until it finds a unique one.
• This all happens when you save a URL to the database, due to the trigger.
• If the URL's already there, no new record - just updates the timestamp.
• It's simple, efficient, and scales well.
• Frontend is written on Typescripted React
