$ sh ./scripts/start.sh

Usage

$ curl -sX POST -H 'Content-Type: application/json' 'https://s.watfaq.com/shorten' -d '{"url":"http://a.very.long.url"}'
{"short": "https://s.watfaq.com/1"}

{"original": "http://a.very.long.url"}

TODO

• auto redirect for original url
• replace in-memory storage with Redis or other persistent stroage
• implement querystring support

Pitfalls

• slice in Golang will auto grow length
• atomic inc should be used carefully
• must wrap a new ResponseWriter to get the status code
