#Fyber Offers API Web Client

Simple web client to consume Fyber API and render result offers in a HTML page.

Based on Sinatra, uses HTTParty as HTTP client.

###Story

Following the commit history, you can see this app was developed in a test-drived way, "outside-in" approach.

FyberClient is the "low-level" implementation of the Fyber API HTTP client with only one public method #call, returning a raw response. It is a default client in the OffersRepository which takes care of validating the response and extracting offers from it into an array of offer objects (OpenStruct is used for simplicity) which are then rendered into HTML.

Current version tries to keep balance between compactness and amount of abstractions. If the app would be to develop further, it would make sense to extract such responsibilities as raw response validation and offers extraction from OffersRepository and into specific classes which would be composed in OffersRepository leaving it only to communicate with injected clients and return offers objects for HTML render.
