URL Shortener App Development

Please develop a simple URL shortener app. This app should be designed to create a short URL for a long (original) URL. The primary function of this app is to redirect users to the original URL when they click on the short URL. The idea isn't to build a shippable product, it's just to see your process.

Requirements

• Use Ruby On Rails
• Ability to enter a URL and get back a short URL
• The URL should be validated
• When the user hits a short link, the service should redirect to the original link
• Links will expire after a standard default time span
• Shortened links should not be predictable
• A very simple UI is fine

Stretch Goals

• Short URL is automatically copied to the clipboard
• Basic analytics (number of times visited)
• API

Note:

• Anything aside from the above, you're free to make assumptions.
• We will have a follow-up session for you to run through the thought process and the solution.
