Recently I wanted to create a URL shortening service for SharePoint 2013. Yes, SharePoint 2016 ships with “Durable Links” but many places run older version. Yes, there are commercial software packages available for sale but management and budget approval can be challenging.
Why not create a simple redirect ASPX with a Custom List of URLs?
Check out the brief video below to see it running live. The Install PS1 script will create the needed List and upload front end files (ASPX + JS).
