This challenge is designed to get you out of your "comfort zone" and expose you to other libraries & patterns you may not be familiar with. This isn't going into production so have fun with it!
Write a web application that allows users to take a long URL & convert it to a shortened URL.
Example:
http://really-long-url.com/the/page/I/am/looking/for -> http://localhost:4000/abc1234

-
Accept a long URL
-
Generate a short local URL like
/abc1234 -
Store the short URL & the long URL together
-
Redirect visitors to the long URL when the short URL is visited
-
Track the number of times the short URL is visited
-
Provide a statistics page for the short URL, such as
/abc1234/stats- Visiting this URL should show:
- short URL
