Miny - A simple URL shortener

Miny is a simple URL shortener built on Sinatra and Redis, using Grape for a RESTful API implementation.

The Sinatra web frontend uses the API anonymously when shortening a URL. While the API can provide information about a short URL ID (sid), the Sinatra frontend is responsible for 301 redirects for those URLs.

Configuration

Miny obeys the RACK_ENV environment variable, mostly to determine which Redis DB to use. These are configurable within config/environments/{development,production,test}.rb.

The site name, URL, and description can be set in config.rb. These are solely used on the Sinatra frontend for page titles, headings, and URLs.

API specification

The API is self-documenting, and can be inspected at /v1/spec.

Unregistered API requests are throttled to 10 requests per minute, up to 100 per hour. API requests that pass a valid key are throttled to 50 requests per minute, up to 500 per hour. Currently, all throttling is IP-based.
