PowerNap - A short but strict REST service framework


    use PowerNap;


PowerNap is simple way to write strict and concise restful web APIs.

The core of PowerNap is the PowerNap::Controller. This role provides a number of default methods and a verb dispatcher. Given a `PowerNap::Verb` `Enum` and a `Map` the dispatcher routes to the relevant method and attempts to call the method with the given `Map`. If there is a type mismatch or missing required pairs a 501 response will be returned, 500 if any other exception is thrown and the method controlls any other responses.

All returned values are classes which implement the `PowerNap::Result` role. These result objects can be introspected as to their error code, if they are an error and impliment an `.ok(Str --> Map)` method to allow localised error messages in chained method calls. All result objects implemt the `Serialise::Map` ([see](, as such calling `.to-map(--> Map).&to-json` will provide a serialised response.

When selecting response codes for your controller methods you should consider recent [HTTP RFCs]( or similar.
