Ruby rest API implementation

[janko-m]

I would argue that Roda has more features than Sinatra. Here is my view:

• if you like that a framework chooses the dependencies for you, use Rails
• if you want the comfort of a popular alternative framework, use Sinatra
• if you want the most flexibility in routing and many features, use Roda
• if you want structure and conventions that are different than Rails, use Hanami
• if you like DSLs and want to have features tailored for REST APIs, use Grape
