Link Shortener Take Home

So let's make a link shortener. Let's make it with rails. Let's use Postgres.

Let's give it test coverage!!!

Please clone this repo and push to a new repo:

1. git clone git@github.com:Fullscreen/link-shortener.git
2. git remote set-url origin git@github.com:USERNAME/link-shortener.git
3. git push origin master
4. Send us the URL to your repo when you are finished.

DO NOT: fork or PR your updates.

Features

1. Root should render a form in which you can drop a URL. When you do, you'll get redirected to a page with its shortened URL and an admin URL.
2. When you go to a shortened URL, you should be redirected to the original URL that was submitted, as long as the URL is active. Also count the usage.
3. When you go to the Admin URL, you should be given the ability to expire the shortened link and see how many times your link has been used. When a link has been expired, render an empty 404.

Other thoughts

1. Your solution should be scalable but not insanely so. If we handed this to our marketing people and they made 1k urls a day each getting hit 20k times a day, would it fall over? Will we talk about scaling to higher numbers in person?
2. It doesn't have to be pretty. Render HTML on the backend or the frontend, whatever is easier for you. This should be a 2-3 hour project.
3. If you have a question, ask! (But yes there's some deliberate vagueness here.)
4. Don't just use a link shortener gem. ಠ_ಠ
5. What is a link shortener? You should be able to shorten a long URL like https://www.example.com/really/long/path?with=query_params to something much shorter. Shortened URL would be something like http://localhost/s/xYz123. Think goo.gl or TinyUrl.
6. The URL for the link admin page should be obfuscated. Think craigslist.
