Yakports

A demonstration of how to use Yaks to build a hypermedia API. It also contains some helpful snippets that might make it into Yaks proper, such as how to set up integration with Grape, or how to handle pagination in a CollectionMapper.

You can browse the API using the HAL browser

or try it on the command line with curl.

Some example URLs

http://yaks-airports.herokuapp.com/countries/DE
http://yaks-airports.herokuapp.com/airports/TXL
http://yaks-airports.herokuapp.com/countries/DE/airports
http://yaks-airports.herokuapp.com/countries/DE/airlines

Use the Accept header to request different formats.
