There are so many web applications available for shortening URLs to share online. TinyURL is one of the originals and has been around longer than I can even remember. Their service is always online and it works perfectly for translating into tweets or posts on Facebook.
In this tutorial I want to build a mini-app which will generate tiny URLs right from your web browser. You could install this script on any domain and you’ll be able to generate dynamic links using Ajax without even refreshing the page! Their service doesn’t have a detailed API but it’s enough that we can pass a full URL and get the tiny version back as a result. And that’s just enough functionality for this app to hold some value when hosted on a 3rd party website.
