Overview

Parses and validates a sinatra params hash based on the endpoint definitions. Note that you use this like a sinatra middleware (using a ‘use` directive in the body of the sinatra class), but it hooks into sinatra differently so that it has access to the params. It’s more like a mix-in, honestly, but we piggyback on ‘use` so that it can take a config block.

#validate_and_parse_params(app) ⇒ Object

Sinatra dups the app before each request, so we need to receive the app instance as an argument here.
