Short URL

A simple implementation of URL shortener built with Sinatra with a Redis backend.

Installation

To run this URL shortener, you need to first set up a Redis server. After that, you can start it as you would any other Rack app:

git clone https://github.com/isundaylee/short_url.git
rackup -p 3000  # start it on port 3000

Usage - HTML (browser)

A demo of this app can be found at http://jiahao.link

To create short URLs, simply go to http://yoursite.com. You can both create short URLs with custom names or ones with automatically generated names.

To access a short URL, simply visit http://yoursite.com/name (which is also returned to you in JSON after you created the short URL), and you will be redirected to the actual URL.

Usage - JSON REST

To create a short URL (you can also omit the name parameter to get a randomly generated name that could be as short as 2 characters):

POST /

Params: {'name': 'google', 'url': 'http://google.com'}
Response: {'url': 'http://example.com/google'}

To retrieve the actual URL:

GET /google

Response: {'actual_url': 'http://google.com'}
