A simple personal URL shortener backend.
To shorten a link, you can use something like curl
to POST the long link.
curl https://vgburl.shuttleapp.rs -d "https://example.com/a/really/very/extremely/long/link/that/is/too/long/to/reasonably/type"
If successful, you'll get a HTTP OK along with a 9-digit code in the body. You can then use the code as a route which will redirect to the long link.
