• Displays history of links created with removal functionality
• Successfully deployed and hosted on AWS using custom domain name with SSL Certification

• One initial challenge we faced was if users input a URL with just the domain name, if that was retrieved from the database and used as a href attribute within links, it would see it as relative URL and not external. We therefore built a simple URL parser to add http:// prefixes to URLs. As a bonus side effect, this also helped reduce possible duplicates within the database too.
• Another fun challenge was creating a recent history of links created using local storage. On first look we realised "oh, you can only store strings, but we need to save the long and shortened url together!". With further reading we discovered we could stringify the data into JSON strings and just parse it back to JavaScript when we needed to display the data.

• Analytics (e.g. clicks on shortened links) - DB table modifications
• Richer styling including animations with Framer
